Degraded raid 1 which drive to buy?

Dear All
I have 6 Xserv (2009) with raid 1 on each.
Today one of my Raid 1 is degraded. I can't found the same harddrive on sell to repair the raid 1.
Does someone can give me a compatible harddrive? Does a list exist?
My harddrive is WDC WD1002FBYS-43P1B0 Media
Perhaps every harddrive SATA could work...
OS : 10.5.8

Hi Fred,
You should still be able to buy the Apple 1TB drive module from Apple or from a reseller. Although some non Apple drives work in the xserve it's a bit hit and miss so if the machines are in a production environment then best to get the real thing.
Thanks
Beatle

To transfer your current hard drive I like the free application SuperDuper. It makes a bootable copy of everything on your hard drive http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html You'll need a cheap SATA external hard drive case. Put the new drive in the case then format and partition the new drive and clone your old drive to the new one. Check that it's set up right by booting up from the external drive. Then replace your old hard drive with the new one and put your old one in the external case.

i don't have any experience with DLNA TV's but i recently moved my iTunes library to a NAS. streaming content to airport express remote speakers and TV2 works great. however, i have all my gear hardwired to my time capsule (except the airport express) so i'm not sure how well streaming e.g. HD movies to TV over wifi works.
i have a Synology DiskStation 411j and am very happy with it.

Upgrading Controllers firmware on a degraded RAID 5 array

Hi guys
I have been told that upgrading the controllers firmware on a degraded raid array can cause a loss of configuration. I have been doing this for over 1 year and it has never happened, it sounds more like a myth to me that anything else but i would like some advice on it, if possible.
Is it true that the RAID Configuration can be lost by upgrading the RAID Controller? In theory isnt the RAID configuration kept on the hard drives?
Thanks in advance,
Pedro

No - this is not a myth. It is entirely possible to lose access to the storage either temporarily or permanently.
It is extremely bad practice to upgrade any system with a degraded component no matter how small.
Which particular array have you been upgrading?
In most arrays, the configuration is saved on multiple disks - on some arrays as a n-way mirror where n is the number of disks in the tray. However unless you know exactly what the implications are, it is extremely important that firmware updates are not carried out on degraded arrays.

Degraded raid 1 SATAS

Everything has been working great on my 939 fx-53, 2 gig Corsair XMS 3200Pro, 2 SATA Seagate 160s, raid 1, BFG 6800 Ultra until I accidently screwed with the bus speeds (I'm a complete moron) which locked up the system and shut down COM ports. Machine wouldn't boot, etc.
I finally loaded failsafe bios settings and utimately got everything straightned out but while bios was in this mode it defaulted to booting from my mirrored drive and Windows loaded (slowly) apparently for the first time, even telling me I had only several days left to registar it.
After resetting everything, including the raid 1, everything works fine except it is showing both hard drives as "degraded" even though using the Nvidia utility it shows them each to be healthy but mirroring as degraded. At F10 hitting R to rebuild does nothing but they appear to still be mirroring though I'm still getting the red flashing warning on boot that this mirrored drive is degraded.
Now when booting my PC takes FOREVER to boot and shutdown but otherwise seems to run fine.
How can I "re-mirror" these drives?
Thank you for any help!

One of the things that I did when I was building my system is to figure out how to do this.
What you need to do is to delete one of the degraded drives. What happened is that at one point in time, the PC booted with only one drive active which put the two drives out of sync. Now there are two active drives and the system does not know which one is supposed to be the "master". So by deleting one, you force the remaining one to be the master and the other will be mirrored off of it.
When you boot, hit F10 to go into the raid setup. Delete the degraded raid that you do not want. Then Ctrl-X and reboot. I am not sure if you have to assign the deleted drive back to the raid configuration or not. But if you can, go ahead and do so. Make sure that first drive is designated as the "boot" drive. Then continue to re-boot and the drives should start the mirroring process.
I hope this helps.

2010 Mac Pro with Apple RAID card - "Drive carrier 00:03 removed"

I've got a 2010 Mac Pro with the Apple RAID card and 4 internal identical Seagate ST32000641AS 2TB drives inside.
I've never had a problem with the RAID card (either battery or in operation) except for one thing:
Almost every time I shut the machine down (which I try to do as rarely as possible), it keeps losing Drive 3, the spare.
(See RAID Utility event log snippet below.)
[I wish I could understand why this Apple RAID card keeps losing the spare across power-cycles/reboots, but I digress.]
So I just adopted it as the spare and it spawns the rebuild and many hours later, everything's fine again.
... until the last time I rebooted (Jan. 2nd).
After the usual "I lost the spare" message upon login, it began the rebuild.
But this time, about 11 1/2 hours later the rebuild stopped and RAID Utility reported "Drive carrier 00:03 removed".
Bay 3 is now missing in the Controller view.
I powered off the system last night, and left it off overnight. Today I took all the drives out, blew the dust off and reseated them.
Same thing. Drive 3 is still missing, and now the rebuild task aborted.
The drive bay location shouldn't matter, right? Can I swap the Bay 3 drive with the Bay 4 drive?
I figure one of two things would happen:
(1) It will report Bay 3 as being there but Bay 4 as being missing, same situation as is now. Meaning the problem is in the Bay 3 spare drive.
(2) It will report Bay 3 as being missing (despite a 'good' drive being present) and Bay 4 will be the (unattached) spare, and the RAID set will be unviable. Meaning the problem is with the drive bay itself, not whatever drive is plugged into it.
If "Drive carrier removed" is trying to tell me the disk is bad, why do I not see any log messages about it? I suppose a spare that never gets used could go bad from lack of use, but ... no messages at all?

I was talking about this.
This looks like a RAID 5 setup without the parity to me. I would said it basically a RAID 0.
Also you metioned "I guess that previous spare must really have gone 'bad', despite having never been used! "
I wiped everything out, I selected the 3 disks and clicked on "Create RAID Set" with RAID5 selected and the "Use unassigned drives as spares" option checked. The 3rd disk has always been marked as the spare ever since then. You do not have a choice to create a "RAID5 setup without the parity". If I wanted a RAID0 I would have chosen a RAID0! raidutil now says

Every time the system would 'lose' Drive 3 on boot, I would just keep rebooting until it was 'found', and then manually re-assign the now-'floating' drive as the spare - and the RAID would rebuild.
There was never a problem until the day that prompted this post - when it would not find Drive 3 no matter what I did. I turned the Mac Pro off for several hours until the drives had all cooled down and it still did not find the drive. I left the machine on but unmounted the degraded volume until I got the new replacement drive.
I really don't understand what you are getting at. It's like you are trying to tell me I set it up as a 4-drive RAID5 with no parity(!) and that I was in grave danger because one of the disks was gone. The actual RAID contents (spread across Drives 1, 2 and 4) were never in danger, unless a 2nd disk had failed while the spare was not seen by the Apple RAID card. I wasn't too worried about that happening.

Need help with RAID Card and degraded Raid-5 errors

Dear all,
I recently purchased a used Apple RAID card for my 2008 Mac Pro 8-Core. The installation went smooth, the card was immediately recognized and the battery reconditioned within one night.
So I started setting up a Raid Set with the 4 identical drives which I already used before as a software Raid. But each time the Raid Level-5 Volume is created, somewhat later the status turns red and the Raid is listed as "degraded"!
A closer look at log reveals:
+19:42:54 Drive carrier 00:01 inserted+
+19:42:27 Background task aborted: Task=Init,Scope=DRVGRP,Group=RS1+
+19:42:27 Degraded RAID set RS1 - No spare available for rebuild+
+19:42:26 Degraded RAID set RS1+
+19:42:22 Drive carrier 00:01 removed+
+15:10:57 Created volume “R1V1” on RAID set “RS1”+
So it seems that the drive from Bay 1 somehow gets lost (removed) a few hours after the volume is being created and anysoon later it's being "reinserted"...
Of course, the drive is NOT removed, nobody touched the Mac Pro! Also I did the same procedure 3 times and the result was always the same.
I also tried setting up JBOD and different RAID levels which do all work without a problem. Only when choosing RAID5 (what I intentionally bought the card for), the problem reappears
Anyone any solution or hint for me concerning this problem? Many thanks in advance!

One drive completely broke down later. Replaced that drive and since the problem's gone!

xserve Mac OS X (10.3.8)

Hi
I have seen this before, dont have an answer why but i can help you fix it.
You need someone to look at the front of the Xserve, notice which drive is active and whcih one is not (blue lights flashing) after you have determined which drive is not being used then just pop it out of the bay, wait a minute or so then pop it back in
Once inserted you will be able to run the disutil repairmirror ....... command to rebuild the RAID
Be very SURE which drive is not being used before doing this.

Confused which mobo to buy OC beginner

Im about to replace my old i7 950 to the new i7 4770k haswell processor because of performance and power consumption.
I'd like to pair it with a 32GB ram and Overclock my 4770k up to 4.2ghz only or higher if its still possible on non airconditioned 20 sqm room.
I have a 256gb Crucial m4 SSD, 3 x 3TB red WD HDD connected on DROBO 5. And just now i bought this monster GTX 780 TI.
I am really confused on which board to buy. Features i'd like it to have are listed below
1) WIFI bluetooth built in
2) any LAN booster (if exists)
3) I have no plan on SLI so board with a lot of extra pci-e slots are just a waste.
4) i'd like it to have a thunderbolt (as what i understand its much faster than usb3) but still im fine with my USB3 thats what i use on DROBO but if thunderbolt is faster then its a must.
5) of course USB 3's loads of it
6) PCI 3.0 since i have gtx 780
7) can do overclocking easily
8) i like this SSD Secure Erase idea from asus maximus boards (i hope its not a gimmick)
9) this too ROG RAMDisk if its true
10) Sata 6/gbps
I will be using this rig on a video / photo editing.
here are my choices: (please suggest any other better if you know one)
MSI z87 xpower
MAXIMUS VI FORMULA
MAXIMUS VI hero
sabertooth z87
GA-Z87X-UD7 TH
GA-Z87X-OC Force
Thanks in advance guys i really hate those shiny marketing gimicks that have no use in real life and just adds extra bucks on its product..

Wow, my reply may be long, but I have a lot to say regarding your current plans! Trust me, I'm trying to help you and you do appear to be a bit off track.
First, if you want more speed for Adobe Premiere Pro you need a MUCH better balance of all the components (cpu, ram, gpu, drives, interfaces, drivers, etc.). There are some slight exceptions, but when you have some components that are much faster than others you don't get excellent results and can waste a lot of money. Running 3 potentially fast drives through a DROBO 5 NIC connection is indeed a weak link.
Here's a well written link for "Balanced Systems"
http://ppbm7.com/index.php/tweakers-page/83-balanced-systems/94-balanced-systems
I don't know what you budget is, but if you can spend more than what you target above, get the following items and you would be sooooo set for awhile:
- Asus Rampage IV Black Edition (separate ROG speed control is totally cool - you can run for normal, quiet, power-eff., or turn up the juice for some serious OC'ing for big renders, etc.)
- i7-4930k; yes this is hundreds of dollars more that the 4-core, but has about 50% more speed for the big work.
- 32GB 1600MHz RAM or 64GB if you have After Effects in your plans
- put your 3 WD reds on a RAID 0 array to the SATA connections on your motherboard (use Intel ports, not Marvel for this)
- bet a large drive or two to load in your DROBO for backups
- don't waste your time with any RAMDISK, SSD caching, or other thing that advertise to help speed up PCs; they likely help certain programs, but not Premiere Pro (it is already using LOTs of your resources and having extra RAM (32GB or 64GB does this) is used by Win7/8/8.1 for drive caching already
And if your budget can't swing all of that:
- get 24GB of RAM for your current motherboard
- (optional) replace the 950 with a 6-core (i7-970, i7-980x, or i7-990x)
- overclock to 3.9 (that's pretty easy to do) whether you stick with the 950 or move up
- put your 3 WD reds on a RAID 0 array to the SATA connections on your motherboard (use Intel ports, not Marvel for this)
- get a large drive or two to load in your DROBO for backups
- don't waste your time with any RAMDISK, SSD caching, or other thing that advertise to help speed up PCs; they likely help certain programs, but not Premiere Pro (it is already using LOTs of your resources and having extra RAM (32GB or 64GB does this) is used by Win7/8/8.1 for drive caching already
BTW, my current main rig is a x58 build w/ OC'd i7-970 6-core, GTX 480, 24GB RAM, and LOTs of drives. It really works quite well for HD and even light RED 4k work. I've also experimented with a Dell dual Xeon e5-2687w with 64GB RAM, dual GTX Titan Superclocked GPUs, boot SSD drive and an Areca 8x drive hardware RAID, so I think that I have an excellent feel for what you can get with well built x58 system and also what you can expect for close to state-of-the-art today.
Also BTW, if I had to replace my 6-core x58 system today, I would go with the Asus Rampage IV Black Edition and i7-4930k myself.

Jim

My G RAID thunderbolt drive mounted just fine onto my iMac this morning. And now it will not mount despite my various efforts. I don't know what else to do. Can someone help me with this?

My G RAID thunderbolt drive mounted just fine onto my iMac this morning. I copied some files from another drive onto the RAID drive, ejected it, and worked on another project for a few hours. When I went to mount the RAID drive again so I could work on the project associated with the drive (I'm a freelance video editor) it would not mount. I've tried everything. It boots up perfectly fine, the drive seems to have no hardware problems. It shows up on Disk Utility and in System Information but is listed as not mounted. I've verified it on Disk Utility and it tells me everything with the drive is fine. I've tried all the various restarting my iMac, ejecting and reconnecting the drive, shutting down the whole system and starting it back up, relaunching Finder, and nothing works. Starting to panic because this is a client's drive, I have no idea what the issue is, it worked perfectly fine only hours ago, nothing happened to it in the meantime, and I fear continuously connecting and ejecting it because I don't know what the state is with the data and if this is only going to further aggravate the problem. I've been up and down Apple and g-raid forums and can't get a straight answer anywhere. I need to know that the data is safe, the drive is undamaged, and how to get it to mount on my iMac. Can anyone out there help me with this??

welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

I Need a Good HD and Case Which One to Buy?

I need an external, large capacity (350GB +) HD for my iBook G4. Can anyone recommend a good HD and case? I need to be able to boot from the external HD. Thanks.

Mostly it saves money since you don't have to buy separate drives.
But its also nice to keep certain things separated. I back up two Macs to a single drive, but separate partitions. OS-X thinks they are separate drives and SuperDuper recognises which drive belongs with which Mac.

Software raid 1 drive(s) failed

Curious on what to do with a RAID 1 Drive (s) failure? I've searched the community and cannot find similar issue/answers.
Configuration:
One 1TB OS & App Drive is fine
Two 3TB RAID 1 Drives for Video scratch are fine
Two 2TB RAID 1 Data Drives are my issue
I'm using the software raid in OSX and it shows "2TB Data Drive/Mirrored Offline"
Both drives have "Failed" next to them
I have backup this Data Drive in Time Machine and a recent full back up to a single drive that is off site. I believe I have a good back up strategy with Time Machine and offsite back ups via Voyager S3. I guess we'll find out!
My question is how do I find out if it's a HW issue or SW issue with this configuration ? And then how to go about recovering them?
Initially when I looked in Disk Utility it appeared that only one of the 2TB drives had "Failed" next to it but now after a reboot "Failed" is next to both drives.
My initial hope was that one of the drives had failed and I'd be able to just replace that drive and the RAID System would rebuild from the other drive.
Any assistance would be appreciated.
Thanks

RAID 1 just copies the same data to two (or more) drives at the same time, it's only for mission critical data loss requirements where a drive failure during writing would be catastrophic. Like taking purchasing orders or getting a phone call from ET for example.
RAID 0 is dangerous as the data path is separated to how many drives in the RAID 0 set, one drive glitches and all data is lost. But provides insane speeds.
RAID 5 is a much more reliable, it combines many drives (4 or more for more speed) splitting the data path but also has redundancy factor that if a drive dies it can be replaced and the data is recovered from the other drives. Usually a RAID 5 is in a external enclosure with it's own cooling and hardware controllers, not software based RAID where your CPU is being overloaded.
There are other forms of RAID some combinations like RAID 1+0, RAID 6, 10 and so forth, you can find out more about the more eclectic RAID types online.
RAID 5 is more ideally suited to video requirements for data storage, with perhaps a RAID 0 as a scratch disk or a RAID 0 + 1 (the RAID 0 is mirrored to another RAID 0) if your going to take a while working on it that increases the potential of failure.
Once the work is completed, it's sent to the RAID 5 where it's safe with it's redundancy and speed.
http://eshop.macsales.com/shop/hard-drives/RAID/Desktop
The thing to remmeber with the failed RAID 1 Data drive is the data is still on the drive, even though it failed and perhaps things are messed up a little on it on the directory. All the drive needs is to be told it's not part of a RAID 1 anymore, that it's a normal drive, a simple fix, but I don't know how to go about it.
You have two drives and two chances to recover the data off off, simply disconnect one data drive and reboot, see if it will mount and or you can repair the drive in Disk Utility.
If not pull one drive out and stick another blank one in there and download Data Rescue and simply recover the files to the new blank drive. DR works by simply reading the files themselve, not the file struture or anything else.
Software RAID is unreliable, it depends upon the CPU. Opt to get a external RAID where it's based in hardware instead. Use eSATA if all possible.
Also consider using backup software, like Carbon Copy Cloner which can be scheduled to make a backup of your data during the middle of the night. This way if something happens to either your boot drive or a data drive, the clone won't immediately copy the issue to the other drive like a RAID 1 does.
Also Carbon Copy Cloner makes "hold option" bootable OS X boot drive clones, which TimeMachine doesn't.
Also TM kicks in what, like once a hour? It's likely what caused your issue, CCC will work when you schedule it. TM is for consumers, not video pro's like yourself.
If you need even heavier iron as a external RAID setup and more expertise, then see these guys

Should I replace my MAC hard drive or buy a new MAC?

Recently, my hard drive crashed. I have been debating whether to replace it, which is the cheapest route to go. Or should I get a new MAC. I've had my MAC since 2008, and am constanly using it. But buying a new MAC is expensive, but I feel it may be the safest route to go to aviod any other problems with my MAC. So, should a just replace the hard drive or buy a new MAC?

It would help to know which one of the different 2008 models of MacBook you have. Is it the White one or the Auminum one?
A new hard drive and maxed out RAM would keep your MacBook running with the new ones for a couple of years. Unless you're doing heavily processor intensive work like high end video editing.
For a hard drive try Newegg.com http://www.newegg.com/Store/SubCategory.aspx?SubCategory=380&name=Laptop-Hard-Dr ives&Order=PRICE
Or OWC http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/

My daughter bought a 12" 600mhz ibook on ebay, and I would like to purchase and install for her a combo drive for Christmas. I feel I have missed a few good opportunities on ebay since I am not sure which brand to buy, nor do I know what the differences in description are, ie: some say" slot loading" some say "dual usb"...and so forth. Can anyone give me some direction here?
I know my Pismo G3 powerbook quite well inside and out, and have done most of the upgrades myself, but on this ibook I am clueless. Is this an easy install?
Thanks for any help.
Sarah

The Combo drive in my 800 MHz G3 iBook is a "Toshiba DVD-ROM SD-R2412," if that helps.
DT & T Computer Service sells compatible drives:

If you're looking at used, PowerBook Tech parts out iBooks and sells the parts.
It is not exactly easy:

Which HDD interface for which drives?

Hello,
I have read Harm's and others' excellent advice on drive configuration, but am not sure about which drives to put on which interfaces. Assuming an X99 motherboard has 2 M.2 PCIE sockets, 1 SATA Express port, 1 SATA Express controller with 1 port, 8 SATA 6 GBs, and possibly a PCT RAID card. Which of these connectors would you use for which drive, and why? (I suppose another way to ask this might be which hdd uses benefit the most from increased speed--OS, application, pagefile, media, etc?)
Also, closely related, one thing I cannot discern from what I have read so far is where lies the point of diminishing returns. For a system used for a mix of Premiere/Photoshop/AE, using as HaswellE, 32Gb, and say a 980, how many drives and how much drive throughput is required to prevent HDD from being a significant bottleneck?
Thanks for any thoughts!!

Normally PCI-E slots are a premium for editing systems and config options so I don't recommend wasting those on NVMe drives or adapter cards. I would suggest the Sata ports for storage usage and a SSD OS drive for sure. A SSD cache drive is a good idea as well provided it's big enough. Normally you want a 256GB Cache drive if so.
