Xserve RAId MTBF

Hello,
Acn anyone tell me the MTBF (Mean Time before Failure) of the Apple Drive Modules for the Xserve RAID.
Thanks!

IBM don't seem to publish MTBF figures for their drives. However, other similar drives run in the 1 million+ hours MTBF and I'd be surprised if Apple went with a drive that was way out of line of other manufacturers.
MTBF has proven to be a poor gauge of disk failure rates which may explain why they no longer publish them.

Xserve RAID - Multiple drive failure.

Morning all,
An Xserve RAID I have been called to take a look at is behaving rather erratically! Here's the chain of events over the last 3 days:
(4 x 180GB - RAID 5)
- 2 folders (the largest in size) suddenly appear empty. The capacity and available space do not change.
- Some remaining files and folders appear corrupted / incomplete e.g. Quickbooks company file.
- Data Rescue appear to recover all data, missing files are recoverd as "orphaned" files.
- DRIVE 1 FAILS showing red light and disappearing from RAID admin.
- RAID set shows "degraded" but still accessible due to RAID 5 config.
- Replace drive 1 with 750GB Apple supplied drive.
- RAID 5 set rebuilds automatically showing green and "online"
- missing files in the 2 large folders still appears missing.
- DRIVE 2 FAILS
I believe the chances of 2 drives failing in such short succession are extremely small and I now thing that drive 1 is probably ok and that something else is at fault here.
Xserve RAID is on the latest FW 1.5.1 and no other errors are present.
Can anyone shed any light on this, could it possibly be the controller ?

The act of the rebuild could have been enough to push the second drive over the edge.
I would say... if the Xserve RAID has been running 24x7 since you purchased it, you may want to consider replacing it. The 180 GB drives were discontinued almost 5 years ago from what I recall... 5 years of constant use is really a long, long time for had drives. It's more typical in data center usage to replace drives after about 3 years of use (even if their MTBF is 500,000+ hours, those numbers are rather meaningless). Hard drives fail on a "bathtub curve," where once you get to the far end of it the odds of failure are great, and lots will fail around the same time. You can't rely on the Xserve RAID to run 24x7 for 10 years, or you'll definitely have problems. There is no RAID on the planet you can expect to run for 10 years without issues with the drives... even if you're using $1500 apiece fiber or SAS drives.

Xserve RAID Admin Tool 1.5.1 not quite working

I have an Xserve RAID that's currently at firmware 1.3.2/1.26a according to Xserve RAID Admin Tool 1.5.1. However, when I try to upgrade the firmware to 1.5.1 via the RAID Admin Tool 1.5.1, it just doesn't do anything--it accepts the .xfb file and then...nothing. Quitting out of the the Admin Tool and restarting still shows the firmware at 1.3.2/1.26a. Same thing if I shut down and restart the Xserve RAID from the RAID Admin tool. Any tips? There's nothing stored on the RAID system yet (the array hasn't even been created--it's a blank system) and nothing is attached to it either (I've just plugged in the ethernet links to format it first before I start attaching an Xserve G5 to it). Also, even though the lower controller is showing green and I have an ethernet cable plugged into it, I can't get any info out of it nor can I configure it with an IP address. Only the top controller seems to allow some configuration such as IP address.

Okay, I've solved the problem.
Basically, the issue was that the lower controller wasn't seated right despite it showing a green light in RAID Admin. When I went to visually inspect it, I noticed that despite what RAID Admin 1.5.1 claimed, its light wasn't even on, let alone green. And since the lower controller handles slots 8-14 of an Xserve RAID and my slots 8-14 are totally unpopulated (empty) at the moment, it was never noticed. Now that I've reseated the lower controller, everything is visually showing green across the board and the firmware upgrade is proceeding as expected and it has upgraded the firmware from 1.3.2/1.26a to 1.5.1/1.5.1c complete with autorestart of both upper and lower controller modules.
Basic lesson learned: RAID Admin lies. If possible, visually inspect the box itself!
Thanks to all who responded.

Switching to Xserver/Xserve RAID

Hi boys and girls...
I was looking for a little assistance in switching over to Xserve. Let me give you some background info first.
Were a small studio in London, with only 11 people in-house and the majority working externally whether free-lance, from home or from another country etc. Were mostly Mac based, though 4 machines are those little beige pc things all running XP 2002. At the minute its 1 G5 and a collection of G4 tower's and G4 power book's, G4 cube's and so on. Were all connected to a G4 server running Mac OS X Server 10.2.8 with a very small dual 120GB HD raid thing running Retrospect.
Our problem is, this system was set up some time ago and were starting to outgrow it.
What were looking for is a way to backup all of our current work and archive all of our old work. Most users like to work directly off the server as theres so much file sharing between the macs and pc's, directly updating files so there isnt any duplication etc.
First question, is it possible (and a good/bad idea ?) to have 10-15 users working directly from a Mac server, that stores the archived work for users to reference and also current work which is backed up to tape and duplicated (as we currently have) to another HD?
Secondly, Is the ideal way to be running things? Is there a more efficent way?
Finally, what kind of spec should we be looking at? There's such a huge difference between servers, while were willing to invest, we dont want to go crazy (maybe a little) on costs.
I look forward to your responses and thank you in advance
Marcus

There are certainly some drawbacks with your current setup that mean you should make some changes.
In general, there's nothing wrong with working with files directly off the server, however, 10.2.8 has some issues with multiple users accessing the same files at the same time, so you should look to move to 10.4 ASAP to address that issue, regardless of any other changes you make.
I am assuming that the remote users don't work this way - uploading/download files as appropriate - it would be painful to work off the server remotely.
The only real disadvantage with working with files directly off the server is that if a file is changed erroneously and saved, there's no easy backup.
If the file was copied to the local drive and saved, it's easy to roll back to the previous version by re-copying it from the server, but if that change is saved directly to the server the only rollback involves pulling out Retrospect.
The other change that would make a difference is installing a gigabit switch and connecting the server to it. Even if all the host systems don't have gigabit ethernet, the extra bandwidth to the server will definitely help.
As for a new server, 10-15 file sharing users are not likely to stress the server, do you don't need a top-of-the-line configuration.
You should first decide how much disk space you need. With 500GB drives, the XServe can handle up to 1.5TB on its own, without any additional XServe RAID. However, you might want to consider RAID (using RAID you're limited to 1TB of RAID 5 storage, or 500GB of mirrored storage in the box).
In addition to your current data usage, consider using an online disk backup where multiple copies of the data is stored on the server itself before (or in addition to) backing up to tape.
While tapes offer several long-term archive advantages, they really don't work so well for quick restores of a file or two. Having a snapshot of the last couple of days data online makes it trivial to step back a day or so without having to resort to tapes. This may mean, though, that your 100GB of data requires 200 or 300GB of disk space.
If you do decide than an XServe RAID is the right solution, consider getting it right-sized from the get-go rather than buying it small (e.g. 4 drives) and adding later. While it can be done, adding drives to an existing array is a PITA.
If you do opt for an XServe RAID, and you don't currently have any rack-mounted equipment, consider using a PowerMac G5 as your server rather than an XServe. While similar in terms of performance, the PowerMac can work out cheaper depending on configuration.

Can I move Array from one Xserve RAID to another and keep the data

I'd like to move a set of disk with an existing Array from one Xserve RAID to another. Can I simply shutdown both Xserve RAIDs and move the disk over, assuming I put the disk back in the same order?

Yes, you should be able to do this.
BE SURE YOU HAVE A BACKUP FIRST.

Clarification on how to use Xserve Raid and Fibre Channel without xsan.

First let me apologize for not responding earlier to your response, I tend to get busy and then forget to check back here.
Tod, the answer to your question is No, only one computer is accessing the xserve raid files at any one time and that is via Fibre Channel. However I do have the xserve raids set up as share points via ethernet.
Maybe I should turn that off and only access the files with the one computer that can connect via fibre channel.
I never thought of that. I will try that while I await for your answer, thanks again.
Todd Buhmiller
I have the following setup:
Xserve: 2x2Ghz Dual Core Intel Xeon, 5Gb of Ram, Running 10.5.8 Leopard Server
Xserve Raid with firmware version 1.5.1/1.51c on both controllers, and
Qlogic Sanbox 5600
Apple Fibre Channel Cards in Xserve, and Mac Pro Tower; Apple 2 Port 4Gbs Fibre Channel Card
Mac Pro Tower-Quad Core Intel Xeon 2.8Ghz, 16Gb of Ram, Running Snow Leopard 10.6.4
Here is the problem.
The directory for the xserve raids keep getting corrup, and I use disc warrior to rebuild them. Is there a way to keep the directories from getting corrupt? I am a few pieces of equipment before I can build an Xsan as that is the ultimate goal, but until then, I just need to be able to have the raids funciton as storage without having to rebuild the directories all of the time.
Anybody have any suggestions?
Thanks

Re: Xserve Raid Mounts, Corrupt Directory tired of rebuilding directory
Posted: Jun 27, 2010 1:25 PM in response to: Todd Buhmiller
Are multiple computers accessing the same data on the RAID at the same time?
If so then NO. This is the source of your data corruption and I'm surprised if you were able to get all your data back every time if this is how you've been running your system. Each fibre channel assumes it has full and sole control of every volume it has mounted, no data arbitration is practiced and data corruption will occur if this assumption is wrong.
The only way this set-up will work is to use partitions or LUN masks so the volumes are accessed by one computer at any time. As long as one computer relinquishes control before another mounts it you will dodge arbitration issues but this is a dangerous game. If you screw up and mount an already mounted volume - and there is no easy way to tell if a volume is mounted - corruption will then occur. Sharing data simultaneous at fibre speeds is what XSAN does and to do this you need it.

Intel Xserve, G5 XServes, XRAID, Promise

+The xserve raids will mount automatically to any computer that I connect the qlogic fc switch to+
This is source of the corruption to your data. Any computer that attaches to a drive/partition via fibre channel assumes that it alone is in control of the drive and data corruption is inevitable.
+Is that the issue, should I disconnect the xserve from the fc switch and leave it connected via ethernet?+
Short answer: YES. The ethernet connections are fine because the server is controlling the file arbitration through the sharing protocol. Fibre channel connections assumes complete control over the partition and no arbitration of the file access is performed. It's like two people independently driving trying to drive the same car to different locations.
Depending on your set-up it is possible for the two machines to see and use different parts of the Xserve RAID storage but they cannot access the same areas without SAN doing the arbitration.
Hope that's clear,

Can't copy files to Xserve Raid

Hello,
I'm having serious issues copying files to my work's Xserve Raid. When I try to copy files to it, it stalls for several minutes trying to copy, but making no progress, before giving an error saying:
"The Finder cannot complete the operation because some data in "filename" could not be read or written. (error code -36)"
When I click ok, I get disconnected from the Raid.
Any thoughts as to what could be happening?

What do your logs say? I'd check your afp (or whatever sharing mechanism you're using) and I'd keep an eye out for any fibre channel or LUN messages that might indicate connection/communication problems with RAID itself. (These might show up as LIP messages.)
Sounds to me like an underlying communications issue rather than a file sharing issue but without more information it's hard to say.
Good luck,

Expanding xServe RAID Array - updated info sought.

I don't want to have to reformat the RAID and I don't want to lose data because...
1) The organization will suffer extended downtime.
2) I don't have ready access to 3TB of empty storage to back up the entire contents of the RAID.
These and Apple's documentation are a few of the many different sources of info on this topic I've sought.
With apologies in advance to William Lloyd, who has answered many of these questions.

My (familiar) situation.
I inherited administration responsibilities for an xServe RAID using the latest firmware (1.5.1).
The xServe is an intel xeon dual 2 GHz, running Mac OS X Server 10.6.8
The RAID had six (sigh) drives in the left controller. None in the right.
When I became admin, one of these six was dead. So I went on eBay and got three refurb ADM's.
--one to replace the dead drive.
--another to expand the RAID 5 to a full seven drives. (from 2.5T to 2.73T)
--a third to put on the shelf as a spare.
Now then.
The replacement drive rebuilt beautifully. Happy 6 drive RAID.
I put in the 7th drive and expanded. It took several days.
I'm at the point of "merging" slices that gives everyone pause about losing data.
Much discussion here about whether this can result in added capacity without destroying data relates to earlier versions of Mac OS X Server and G5 not Intel xServes. So that's a point that I think I could use some clarity on. Can Intel Macs can expand the file system with this slice-merging function without data loss whereas Power PC Macs cannot?
Next, my RAID as I inherited it was one slice. That is to say, one volume. One partition. In RAID Admin under "Arrays and Drives" all the little drives display a [1]. They did when the RAID was degraded to 5 drives. They did when I added the 6th drive replacement. They do now, having used the Expansion function under "Advanced" to add the 7th drive.
So, next question. WAS IT EVER SLICED?
That seems to be a deal-breaker for merging slices without data loss.
For this, I looked in RAID Admin to my Events tab which dates all the way back to 2008.
I see exactly zero mentions of slicing anywhere. Come with me on a journey, won't you?
You'll see my expansion and verification up top.
The drive failure in October 2013.
Other exciting things. But no slicing.

Xserve RAID lost RAID 5 array on right/bottom controller

I cleanly shut down an Xserve G5 with an Xserve RAID attached and then powered off the Xserve RAID this morning. I replaced a failing memory module in the Xserve and moved the rack 6". I then powered on the Xserve RAID, waited for a couple minutes until it was fully booted, and then booted the Xserve. When it came up, my RAID 50 volume failed to mount. Upon further investigation, it appears that the RAID 5 array on the right hand disks is "gone". In RAID Admin (Disks and Drives tab), the left side array is visible, but all disks on the right side list status as "OK" and Type: as "Spare".
Configuration: Xserve RAID with 14 250 GB disks. Each side was configured with 6 disks in a RAID 5 array and one spare. These were striped using Software RAID on the Xserve into RAID 50 and mounted as a single volume. The RAID firmware is currently 1.5 and the Xserve is running OS X Server 10.4.3.
To summarize today's activities: under Apple's guidance (as this entire system is covered under a Premium Support contract), I swapped the (bottom) controller for the right side, updated firmware (from v1.3/1.20a to 1.5/1.50), multiple resets of both controllers, repeated forced firmware updates, etc.
Also, I swapped the left set of disks for the right set, and the array from the left set now shows up on the right side, and the missing array from the right is still missing with the disks on the left side. I replaced the disks to their original positions with the same results.
RAID Admin's Utility "Recognize Array" will not perform any operations on the rigth side disks and Apple tells me that there's nothing further that I can do with it.
None of this has solved the problem or substantially changed the issue, and the disks on the right side are still missing their associated array. Apple is unable/unwilling to offer any further help except to refer me to 3rd party data recovery services.
Does anyone have any suggestion at all that might possibly recover the missing array? Is anyone aware of any tools that I might use to recreate the RAID 5 array on the right controller? I was hoping that there might exist some low-level tools with which the disks could be recreated into an array by hand? Are there any commercial products that would work on this? Any other ideas?
Many thanks for any suggestions.

Not sure why you swapped the controllers back and forth
William, I don't think I was clear on this. I swapped the controller with a new controller that I had in a spare parts kit. This was at Apple's request.
really, RAID is not a backup...
I'm well aware, but despite my incessant warnings, users will become lulled in to a false sense of security when something "just works" for a very long time. This array wasn't intended to store valuable data that couldn't be lost, but...
It may be possible for Apple to re-create the RAID set, did you ask AppleCare about the possibility?
Apple has told me more than once that there's nothing else that they can do for me...and yet I keep calling back.
I was surprised that this array was lost when there were absolutely no prior signs of a problem and the system was merely shutdown and restarted cleanly. I'm more surprised and quite disappointed to learn that Apple will do nothing else for me (under a Premium Support contract) to attempt to repair a damaged array. When I asked questions about where the RAID information is stored, I received the answers: "I can't tell you that" and "Apple doesn't release that information". I did not get the feeling that they were working with me, but rather holding my hand while they walked me through published documentation.
I expected that there would be utilities (analagous to filesystem repair utilities) such as RAID Admin's "Recognize Array" that could help repair and recover damaged array data. I think that the lesson that I've leanred today is that I was naive to have expected such a thing without actually having investigated it ahead of time.
Anyway, thanks for your input, William.

Configure Xserve RAID as a single RAID 5 array?

We just picked up a used Xserve RAID with 14x750GB drives, and we want to configure the entire unit as a single RAID5 array. RAID Utility will let us configure each side as a separate array, but not both sides in a single array. Is this not possible or are we just missing something simple?

No, each side of the RAID is logically separate so while you can create a RAID 5 on either side there is no way to create a single RAID5 of the unit. You can create a RAID 50 and make the 2 RAID5s into a single volume software RAID 0 by using Disk Utility to join the two 5s into a single volume but that's as close as it comes.

Repair Utility for xServe RAID?

We have an xServe with an attached RAID consisting of four 350 GB drives. The drives are set up as a RAID. Due to storms/hot weather (air conditioning failed) the server restarted and the RAID powered down. The xServe is fine but the RAID is not functioning. From RAID Admin the drives all show up and are OK but the array is not showing up. Is there any disk repair utility that would be useful on a RAID?
xServe RAID Mac OS X (10.4.6)
xServe RAID Mac OS X (10.4.6)

The fact that it's showing up as spares is a significant problem. The host won't recognize it until the RAID recognizes the array. There is no separate utility to help you with this, other than RAID Admin.
What firmware version is on the array? If it's 1.5, there's a "recognize array" option that you should try. If it's an older version, I'd tell you it would be nice if you could have gone back in time and upgraded the firmware. Since that's not possible, you should call AppleCare (assuming you have got APS&S for Xserve RAID, or the machine is < 1 year old) and inquire about your options.

AFP and Xserve RAID very SLOOOOW

Recently we have been having problems with AFP pegging the Xserve RAID activity lights. Xserve RAID Disk access is very slow.
Machine Specs:
Dual 2.3 GHZ G5 Xserve
1GB RAM (recently downgraded because of memory problems after a power outage)
1x80GB Xserve drive module
3TB Xserve RAID 5
Xserve RAID has been upgraded to 1.5 FW and has both ethernet connections connected.
The whole story is we had a power outage last week. The servers all came back up fine. Throughout the day we noticed that the file server was acting strange. We checked server monitor and it said that RAM slot 3&4 had problems. We opened up System Profiler and it reported that modules 2&3 were only 256MB! (These are 512MB modules). We brought the machine down and pulled the modules. The machine is now at 1GB of memory with more coming. The next day the machine was incredibly slow and the RAIDs access lights were pegged. Also something was pulling all free memory into inactive memory. After trial and error I've found that if I turn off AFP the RAID is no longer pegged and the memory goes back to normal. I thought AFP was the problem and did a complete rebuild of the server last night. This morning the same thing is happening. Also the logs show nothing is wrong.
All of our Macintosh users are Mobile accounts over AFP. We have around 60 Macintosh users. All of our PC users connect using SMB. We have around 20 PC users. All of our network users work off of the file shares.
Thanks for any and all help,

Check so that the Xserve RAID diskcache settings are not reset/off.
I have had to take apart the RAID controllers and putting them back togheter again to alleviate slowness/"malfunction" making a couple of RAIDs operating like normal again.
I use Helios Lantest http://www.helios.de/ and XRG to measure/stress disks locally and over the network to see if they are working correctly.

Added a 2nd Array on my Xserve RAID, Though it's not appearing in disk utilityt

I have an Xserve RAID unit. Up until now I have just been running 1 side of it with 7 drives on RAID 5 = about 4TB. I recently picked up another identical RAID unit with 7 drives to fill out the right hand bay of the unit doubling our capacity. I have installed these and initialised the array which took about 48 hours, it's now showing as online and green lights all the way.
Now I've gone to make use of the extra space but it is not showing as available in the mounted RAID icon on the desktop, nor will the new array appear in disk utility. When I access server admin however, on the overview screen it shows I have 8TB on offer. Contrary to this in the system profiler the 'Fibre Channel Domain 2' is not reporting any SCSI devices unlike 'Fibre Channel Domain 0' - Not sure this is related.
If anyone can help me gain access to the new found 4TB I would be greatly appreciative.

it is not showing as available in the mounted RAID icon on the desktop
It won't.
The XServe RAID is really built as two independent RAID controllers and drive sets in one enclosure.
The 7 left-most drives are connected to the top controller, and the 7 right-most drives are connected to the bottom controller. They are independent. There's no way to build a single 14-drive array - the best you can do is build two 7-drive arrays.
What you should find is that if you connect the bottom controller to your server, the second array should appear on the desktop, separate and distinct from your existing volume.
If you really need to expand your volume to cover all 14 drives then you'll need to use software RAID 0 (striping) on the server to meld both of the 7-drive arrays into a single logical volume.

Looking for some ideas for setting up and xServe RAID

Everyone,
Here is what I would to do. I have a new xServe and 7TB RAID. I would like to set all of my end users up with Portable Home Directories. They all have laptops and I would like to use their PHD as my backup source. I would set them to sync in the background a couple of times per day and then write to tape at night.I have about 60 end users. I would also like to use the same xServe and RAID as my Kerio mail server and mail store. What I am looking for is some ideas of how to go about setting up the RAID. I was orginially thinking of setting up as one big RAID 5 using all 14 drives. What I would like to know is what is the number of drives that would need to fail that would render the RAID unrebuildable? I am now thinking about splitting the RAID into two 7 drives in RAID set up as RAID 1+0.
I am not sure if I phrased a lot of this currently, but here is quick recap of what I would like to know. What would be the best way to set up a 7TB RAID to store PHD and my Kerio mail store that provides me the most redudant and fastest acccess.
Thanks in advance.
Sincerely,
Daniel Krajc

Daniel,
I'd suggest a 6 disk RAID 5 plus a hot spare for each side. It will give you about 2.4 TB capacity per side (4.8 total), and it can tolerate 2 drive failures per side without losing data, provided there is sufficient time between failures for the RAID set to automatically rebuild on the hot spare. This window is 8-12 hours.
Note with Xserve RAID the two sides are totally independent in the data path -- it will look like 2 separate LUNs. If you want to combine these at the host level, as RAID 0 or RAID 1 to look like a single volume, you can. But the Xserve RAID will not combine them itself... the RAID controllers are independent... it might as well be two separate RAID volumes in the same chassis.
I assume you'll plug this into an Xserve that is serving as an Open Directory server and a file server?

Problems with Xserve RAID

I have been having problems with Xserve RAID, which happened in a close time span, but may not be related. The Xserve RAID is set up with 7 disks with RAID 5, totaling to 1.3TB in storage capacity.
First, the first disk failed and the RAID system was degraded. Since I got a very similar 250GB harddisk (but without "Apple Firmware") I tried putting it as a replacement. It was recognized but it became a hot spare disk, even though I did not set the system to use hot spare.
Later Mac OS X reported that the Xserve RAID's 1.3TB volume was unmounted. I check with Disk Utility, and it reported a lot of errors. I ended up with about 70GB of files in lost+found, and I confirmed that many files were missing. Disk Utility could not really fixed it.
I put back the failed disk, and Xserve RAID successfully rebuilt the array. I did "Background Array Conditioning" to perform surface scan and mapping of bad blocks. It completed without error. I then did "Verify Parity Data", and it completed but with error, as follows:
Event:
Disk 5 Reported An Error. COMMAND:0x37 ERROR:0x64 STATUS:0x81 LBA:0x119E6880
Description:
The drive reported ATA error. This is a failure in the communication from the RAID Controller to the drive.
Any idea what is happening with this Xserve RAID? Bad disk? Bad controller? Or what? Any help is appreciated.
Thanks,
Xserve RAID Dual G5 2.0GHz Mac OS X (10.3.9)

After reading here and there on the net (including this forum), yes I realized that the "Apple Firmware" thing may be significant after all. But since I set the Xserve RAID to use RAID 5, a failure of one disk should not affect data integrity. And surface scan was successful, implyingthat all disks are now free from defects. So why did it lost 70GB worth of data? I experienced disk hardware failure often with Windows system but never experienced losing data while the hardware seems to be fine. Without knowing why this happened, I feel scared to put data on Xserve RAID, and this is ironic since this 1.7TB Xserve RAID is meant for storing data safely...
