Apple RAID Utility Raid 0 one disk roaming making raid set not viable

Hello!
I have a problem with RAID 0. In the picture below you can see that one drive was set to missing and RAID set RS1 has been set to non viable. However all four drives(Bay1-4) are set to be verified with status good. However as can be seen from the picture Bay 3 is set to status: Roaming
I don't know what I can do here. There was some talk on other discussions but nothing that helped me
Thanks to anyone that read this and try to help me. If you need more detail I will be more than happy to give them to you.

An error with drive in bay 3 threw it out of the RAID, breaking the Striped RAID. You data will be very difficult to recover, since the data are striped on two different drives, and one of them is no longer part of that RAID set.
You now need to re-initialize the RAID set (which destroy what is left of the data) using the same or different drives, and restore the data from your backups if desired.
I recommend writing zeroes to every block on the troublesome drive before even thinking of returning it to service.

Apple RAID Card after System Disk Failure: Volume visible but not mountable

Hi,
Im running a Mac Pro with 10.5.8. Server has a workgroup server. The Mac Pro is equipped with a Apple RAID Card running three 1TB SATA Drives and a SAS drive for the System. The three 1TB drives are used by a RAID5 to store the data the SAS drive was used for the system. After a power failure the SAS drive was dead and I installed a new drive and reinstalled the system with the DVDs that were in the box. After that the RAID5 is not mounted by the system anymore although I can sea it in the RAID Utility but not with its volume name but with the name R2V1.
What can I do to save the data on that RAID?
Thanks
Phil

It's tough to find info on your specific model but the Raid card listed in the Apple Store (http://store.apple.com/us/product/MB845Z/A?mco=MTY3ODQ5OTY) states you must use all SAS drives or all SATA drives with the card. Are you sure that the drive that died was a SAS drive?

Disk Utility: For one Disk it isn't possible to change anything

Good Morning everybody
First I think my Spec's are important:
MacBook Pro (13-inch, Mid 2012)
2.9 GHz Intel Core i7
16 GB 1600 MHz DDR3
Two Disks: Samsung SSD 840 EVO 250 GB (normal Startup Disk)
Toshiba HDD 750 GB
Intel Hd Graphics 4000 1024 MB
OS X Yosemite Version 10.10.1
And now to the thing I did that the Problem appeared:
After a very long discussion with the Apple Support Help Hotline I decided that, after a Backup, I wil do this: OS X Mountain Lion: Erase and reinstall OS X to try something out, and then will restore my backup.
It all went perfect till the thing with restoring my backup. In the Menu I get when I press (CMD + R) I tried to restore the backup. But then, in the middle of the process, the system cancelled the process automatically and shut down. So I started the Mac again, it automatically came into this CMD + R menu. So I went into the Disk Utility to watch what happened. Since then my two Disks are shown the same way (picture): It is not possible to change anything, except running the First Aid thing. Luckily it was possible to install the OS X and my Backup on the HDD, but for me this is only a temporarily version because the SSD is at the moment completely blocked.
Goal:
It would be great when I can add/remove/change partitions on both Hard Disks and when, at the end, it would be possible to install my Backup to the SSD and use the HDD as a "external Storage" again.
Thanks for all your responses & you can ask me everything if you need more information.

This solved my problem.

RAID Utility software not available in OS X Mavericks?

Up till yesterday I have been using a RAID card in my Mac Pro (Mid 2010, 4 x 1 TB SATA, initially as RAID-5, now in a RAID-10 setup) under OS X 10.8.5 without any issues, and the RAID utility allowed me to check the status od me disks, event log, and the battery status / refresh cycles for the RAID card. Last night now I upgraded to OS X Mavericks. The upgrade went well, things appear to work OK, obviously at least half of my RAID-10 array is in use — however, I can't find the RAID utility, check the status of the RAID-10 system and the battery status of the RAID card. The disk utility shows the RAID set - but none of the underlying features (individual disks and their status, logs, battery) — am I thrown back to a soft RAID, and my investment into a RAID card has evaporated?

Thanks a lot, Seliqui! the reason why I did not find it is that a) after the upgrade to Mavericks, the icon that I previously had parked in the dock no longer worked, and b) the new location for the utility can't be found anywhere on the Launchpad. I suspect both effects are an indication that they missed to add the new directory to the command path. I can hardly imagine that this was deliberate because if you have a RAID card you definitely want to have access to that utility — not just in case of a disk failure (I have had a couple of these!), but also in order to stop the user from doing things one is not supposed to do while the battery is reconditioning.

What happened to Raid utility in mavericks?

I have an early 2008 mac pro with apple's hardware raid card. After doing Apples "free" upgrade, I no longer have raidutility under utilties... What happened?
I'm also stuck in and endless loop of appstore trying to update itunes and hp printer driver...
Sigh.
Jason

Hi Jason,
I would claim that the RAID Utility is really a System Administrator app, and not a user app. And with the end of the silver Mac Pro models and Xserve already out of production, the Apple Raid cards appear to be a thing of the past.
As I manage 14 Mac Pros, from Early 2008 through Mid 2012 models, I'll have to figure out other ways to perform the mirrored disk function. I think it will be some kind of cron job that runs rsync to keep pairs of disks synced...
I've just installed Mavericks on a test Early 2008 Mac Pro, with RAID card, upgrading from OS X 10.6.8. So far, everything seems to be going pretty well. Next week's project is to compile Macports, and install our standard set of Unix utilities. This will likely be a challenge, for such a new OS.
anyway, glad to help,
Roy

B-Series Disk details RAID rebuild issues after disk removal

Hi,
after removing and reinserting one disk from a RAID-1 on our B-Series blades for testing, the disk details for the reinserted disk will not be fully shown.
Only the disk itself gets detected and "Presence" shows "equipped" (see attached screenshot).
It also doen not look like the RAID would be rebuilt.
So does anyone know how to:
* Get all disk details again.
* (Automatically) reinitialize the RAID rebuild.
* Monitor the RAID status.
* Be notified of a RAID failure.
Ralph

Hi,
not very happy with the fact that UCSM doesn't display a disk or RAID status.
Any chance that we might see that in an upcoming release?
We are using ESX 4.0 U2, RHEL 6 and W2K8 R2.
Hope that MegaRAID tools would work and can be queried by SNMP (or so).
I found out how to get the disk data again and get rid of the following warning that obviously comes with not getting the disk details:
Description:
* Server sys/chassis-1/blade-6 does not fullfill Service profile vmw66 due to incompatible-number-of-local-disks
* ID: 828447
* Cause: server-failed
* Code: F0337
Solution -> re-aknowledge the server...
Any chance that this might be a bug (in 1.4.1i)?
edit: Seems that has been around for a while:

Setting Up Dual Sonnet Fusion/WD RE2 RAID 0 Arrays in Disk Utility

I've just received my 2nd Sonnet Fusion 500P enclosure, 5 500GB WD RE2s, and the Sonnet Tempo E4P card. See this earlier thread for more info:
[http://discussions.apple.com/thread.jspa?messageID=6034612&#6034612]
I assembled everything with no trouble; drives into trays, trays into the enclosure, card into the Mac Pro, etc.; all went well.
Next, in Disk Utility I initialized the 5 drives, and set up a striped RAID O array. I used the largest RAID block size of 256K. And again, everything worked perfectly; I now have a 2.3 TB RAID setup mounted on my desktop.
Next, I created 2 folders on the RAID, one for all of my Final Cut Pro media files, and another for all my DVD Studio Pro media files. These files are currently stored on the individual (not RAIDed) drives in my first Sonnet Fusion enclosure. I'm now in the process of copying over all of the files to the new RAID.
When that's finished, my plan is this: I will shut down, and power down the original Sonnet enclosure. When I start up again, one by one, I will open up my FCP and DVDSP projects (the project files themselves are stored on my internal boot drive, and backed up to another internal drive) and when the media can't be found, I'll reconnect the project to the media on the RAID.
If this all goes well, I will then erase the individual drives in the first enclosure, and build a 2nd RAID 0; I'll copy/clone everything from the first RAID enclosure to the 2nd.
If you're still reading, does this sound like a safe way to do things? I want to reconnect everything while I still have 2 copies of all of the media files; once I have the 2nd RAID built, and everything is copied back to it, I'll have a backup of everything again. If there is a better, more secure way to do it, I'm open to suggestions.
And being somewhat new to RAID, one more question I have is, are drives in a RAID system more prone to failure than if they are running as stand-alone drives? I've used the WD RE2s a lot, and I like them; they seem very reliable. (I now have 14 of them, in total). But does the RAID system itself put the drives more at risk?
Thanks to those with the patience to read through this, and hopefully offer some advice.

Always have two backups or sets of data. If you are going to erase one set... then for a stretch of time you only have the one good copy I take it? I guess the originals would be one good set, so you are safe.
You realize you can unmount drives connected on Sonnet controllers, right? No need to shutdown your computer, just the enclosure(s). Couldn't tell if that is what you said anyway.
I don't use internal drives for backups, just external SATA and at least one on FireWire. One backup is always off line at any time. And enough juice on the UPS to carry me through what I am doing or can safely get past.
I just read one of AMUG/michael's post on a controller that supports hardware RAID and ability to map out bad sectors "on the fly" which is about the only time I worry about a failure. That, and UPS, and beware of OS patches and updates (one security update affected SeriTek on some G4/5s).
I'd say you've done a lot for being new to RAID - and using the same make/model/revision for all your drives helps a lot. Buying together, and having at least one 'spare' if one fails, is also good insurance.
Some poeple use 4 drives in a 5-drive enclosure. For heat and ventilation and because sometimes it might be ideal for performance. Never used or seen the 500P up close but I suspect it is well built.
You could build a 2nd 500P and either increase performance or capacity or use 2nd as backup. If you don't need to copy 1GB per minute, then a concatenated RAID fills drive A before putting data on B and is more secure than a stripped RAID but still shows up as one large volume.

Quicktime disables one of the disks in my RAID 5 array.

Hi,
I have just installed ver 7.2 of Quicktime and after I began playing a Quicktime movie file one of the disks on my RAID array came up as failed. I have managed to recover this problem, but is there anything I can do to stop this happening again???... (apart from going back to XP )
Cheers,
Mark.

I just had the same problem. This is the second time I'm having this issue, the first time was when I installed Quicktime the first time a couple months ago, I don't remember which version it was (cannot remember if it was during the installation of the first file I played). I lost one of my drive in my RAID 0 or 1 (mirroring), fortunately I was able to rebuilt the image.
The second was few minutes ago when I was trying to play the HD trailer of Rush Hour 3. But this time my computer could reboot, my 2 drives was marked as failed!!! I was really scared to lose my data. Fortunately when I went in the RAID controller setup, it was able to find one of my drive and now the second one is rebuilding. The first thing I did when I rebooted was to uninstall that crap of quicktime and will never install it again.
My config: Vista Ultimate 64, motherboard Asus P5B Deluxe with Intel Matrix Storage. Quicktime 7.2 updated few days ago.

Raid Utility not an option on Lion Recovery Disk

I am trying to delete a single RAID set that includes the startup volume. I booted up with the Lion Recovery disk but only the disk utility is available as an option to erase information and no RAID utility is there. I erased the startup volume and am re-installing. If this doesn't fix the system so that I can try recreating the RAID set, does anyone have suggestions how to get back to the original four 2TB drives?
Thanks, Alison

To refine what the Hatter is saying...
1) take an external drive. (USB is really slow, but can be used in a pinch. Firewire interface is much faster, and worth the price difference. It should be a 3.5" drive, and have its own power supply.)
2) Install Mac OS X on the External drive.
3) Boot from the External drive. Now you have the full capabilities of Mac OS X to act on everything else in your Mac.
The Hatter often proposes that:
... rather than using a Utilities/Installer DVD or Recovery_HD to Install Mac OS X on an External drive from scratch, you can do just as good a job (and get a "free" bootable backup in the process) by:
2alt) Cloning from an existing Mac OS X drive to that same External drive.
[I am not sure you have that option at the moment, but it may be available when your system is stable again.]

How do you break a RAID 1 created in Disk Utility and retain data?

Good Morning all !!
Quick subject question.
Background: I have 2-3 TB of important data that i use only rarely. I purchased two 4TB external drives. I could not use a 2 drive raid enclosure because of the fan noise in the studio. I selected 800 firewire fanless enclosures. The technican talked me into using the Disk Utility Raid 1 in Mountain Lion OS.
Problem: I only plug them in when needed probably once a week. The raid rebuilds every time I use the raid. That takes about a day. This arrangement is less than ideal.
Question: Can I break the raid and still have the data intact on 2 separate drives? Of coarse I would do it when they a rebuilt.
Thanks.
Mike

HOW TO MOVE DATAFILES FROM ONE DISK RAID TO ANOTHER:PLZ HELP ME :=)

Hi all,
For Tunning reasons : perform The I/O from the Instance to datafiles (database). I decide to move some Index datafiles from One DISK RAID to another.
I'm on Linux Redhat Server and Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
My database 's On PRODUCTION and there 're many web applications updating some databases tables and for sure using Index tablespace. I preapared yet my procedure to move datafiles but I'm posting this to be sure that I will not have BAD EFFECTS on my Oracle database.
So I plan without SHUTDOWN MY DATABASE to these steps :
/*Step1 : */
ALTER TABLESPACE INDX OFFLINE ;
/*Step 2 : move datafiles to new disk raid*/
mv /u01/oraindx/DB01/indx01_05.dbf /u01/oraindx2/DB01/indx01_05.dbf
mv /u01/oraindx/DB01/indx01_06.dbf /u01/oraindx2/DB01/indx01_06.dbf
mv /u01/oraindx/DB01/indx01_07.dbf /u01/oraindx2/DB01/indx01_07.dbf
/*Step 3 : */
ALTER TABLESPACE INDX RENAME DATAFILE '/u01/oraindx/DB01/indx01_05.dbf' TO '/u01/oraindx2/DB01/indx01_05.dbf';
ALTER TABLESPACE INDX RENAME DATAFILE '/u01/oraindx/DB01/indx01_06.dbf' TO '/u01/oraindx2/DB01/indx01_06.dbf';
ALTER TABLESPACE INDX RENAME DATAFILE '/u01/oraindx/DB01/indx01_07.dbf' TO '/u01/oraindx2/DB01/indx01_07.dbf';
/*Step 4 : */
ALTER TABLESPACE INDX ONLINE ;
Please verify my procedure and tell me the precautions that I should take care :=)

About: making RAID sets - partition independant?

(the querry made simple: look last 2 lines)
When making a RAID set, whatever the type it is, will it rely on the partitions or on the disk itself?
In the Disk Utility help it keeps mentioning "disk", and when I was about to create a set, it also asked me about "disk".
I have set up 2 partitions for the purpose of testing RAID for me, being about the same size on a big backup drive.
The drive itself also has a bit of free space filled with original files.
So I wanted to mirror, say, RAID test 1 and RAID test 2, both of them being on the same disk.
Will it work?
Or will it wipe my disk?

A RAID may be constructed using individual partitions on separate drives although using the whole drive would be preferred for speed. You could actually RAID multiple partitions on the same drive, but of course what would be the point.
I've actually used two drives each with three separate partitions and created three separate RAIDs of two partitions each. Not particularly efficient but it does work.
There is really no point to creating a RAID of two partitions on the same drive. And, certainly no point creating a mirrored RAID this way.
Any RAID you create with Disk Utility will erase the drives used (or partitions.)
RAID Basics
For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?

Why no RAID options for new disks?

Hi support group,
"My name is Shaun, and I am a mac-aholic"
I inserted 4 new 3TB disks into the bays of my Mac Pro (2012), and there is no RAID option for them.
How I got here:
Inserted the WD Red drives, and they were not initiated.
I "erased" the drives, gave them names, and they appear in Disk Utility in grey drives.
Went to set up the RAID, and move the drives into the RAID, but got an error that they could not be used.
It appears to me that disk utility is not allowing me to fully use those drives. I Have created RAID drives before with no issue in RAID1 with 3TB drives before on this machine. Am perplexed, I thought this to be the easy and simple part of my upgrade odyssey! Did I screw up the initialization? On all FOUR drives?
Now, if I click on the drives, the RAID option does not present itself.
FWIW, I am using OS X 10.9.5, on Mac Pro 5,1. I boot from PCIe card. My end goal is to create a 4-disk RAID 10 using the four SATA connections on the MP.

It was really pretty simple based on your feedback, I powered down, removed the drives from the SATA backplane, moved each drive separately to the USB enclosure, then re-"erased" in OSX-Etended. I ejected each drive when finished, and moved to the next one until all four were re-"erased". Then I restarted the Mac with all four in the SATA connections, and all four were visible and had the RAID option tab. I created the three RAID schemes (two stripe and one mirror), and dragged the drives into the RAID option. Then I hit "create" or some other command to finish the RAID.
Note that I did get an error on the RAID creation. From memory, this was "cannot create RAID without an unmounted disk" or something like that. I cleared the error, and then opened back up Disk Utility. All the RAIDs were listed, and were operational with the green "On" signal. I could read/write/transfer from the RAID. Once I transfer the data to this RAID, I will work on a way to test it, but if any risk to the data, I might just leave well enough alone.
For now, it seems I have a fully functional RAID 1+0 using the four HDD on the SATA connections in my Mac Pro 5,1.

Multiple RAID setups in one Xserve?

Hi hope you can help me, we are a small architecture practice in the market for a new server and we are considering an Xserve and Xserve RAID system. I would quite like to set up the Xserve unit to use two of the drives in RAID 1 to mirror the operating system. My question is it possible and/or wise to have multiple RAID sets in the Xserve RAID unit? For example using four of the bays for 4x500Gb in RAID 1 (1Tb storage) for projects, and then using another 2 bays for 2x250Gb in RAID 1 as well for say Mail, maybe even another 2 bays for holding user home accounts. I understand that with share points this isn't strictly necessary but it seems to make sense to keep functions separate across hard drives for quick replacements. Or is this a lot to ask of a single RAID controller?
Also how easy is to add storage to an existing RAID set-up without destroying the data?; say we wanted to increase the 1Tb project storage to 2Tb easily.
Thanks for your help in advance.
Mac OS X (10.4.8)

Andrew,
I think you are over complicating you setup.
If you do multiple RAID sets the you are really anti-optimiziung. If you asked "How can I get the least performance and lowest capacity out of a RAID?" then I would suggest three mirrored disks w/ spare per controller.
You would have far better performance and capacity if you were to put two drives in the Xserve to mirror, then set up your RAID as RAID 5 across 6 disks with 1 spare (default config).
With Disk Utility you can build multiple file systems on the RAID, so you could slice it up, but again that could be wasting space.
When you get the RAID setup as one file system do not share the root. Set up sub dirs to share:
/Volumes/Raid1 --your RAID root, aka mount point.
/Volumes/Raid1/Mail -- mail
/Volumes/Raid1/Users -- Home dirs
/Volumes/Raid1/Projects -- your production storage
/Volumes/Raid1/Backup -- Save disk images of your server and workstations here.
And yes, changing the size of a file system means wiping it out and restoring from backup.
Also consider the 750GB drives, it's a lot more storage for not that much more money.

RAID Utility - Resize Volume?

Hi,
I've got a Mac Pro with a hardware RAID0+1, 4 x 500GB disks giving me a maximum of 1TB (ish) of storage.
Thing is, the last 500GB disk was an addition and now I want to resize the original 500GB volume to use the full 1TB of storage offered by the array. I can't see an easy way to do it in RAID utility. Is it me or is this something that can't be done?
Cheers,
Stu

Usually the drives have to be formatted separately as well as partitioned separately.
However, I don't quite understand what you are doing. You currently have four 500 GB drives configured as a RAID 0+1 which I would understand to mean two 500 GB drives striped, a second pair striped. That is two 1 TB striped arrays that are then combined into a mirrored array which would be 1TB. Now as I understand you want to resize one 500 GB drive that is already in the array. This I don't get.
