Utility need to saftly mount / repair raid volume over fibre optic

Hi,
was wondering if there's any ideas for the following scenario:
Mac Pro / OS 10.5.x which usually mounts a RAID volume over fibre optic link. The thing is the RAID volume is corrupt, and when any Mac tries to mount it (after being informed that it's damaged, and givent the option to format / ignore...) it crashes.
Another problem is the only way to access the volume is to mount it on a Mac first because they're the only machines with fiber channel cards.
The questions are - is there any way to access the volume without crashing the mac?
Once the volume is accessible, what's the best tool for repairing rAID volumes these days?
Any thoughts appreciated ( i know this is all a bit vague, just looking for general info, opinions). Many thanks in advance.

Hello,
First of all thanks for the reply. The only problem is that I've already tried what you suggested. When I press the option key on the keyboard with the installation cd inserted I see what I am supposed to, the CD, Windows Vista and Macintosh HD. When I select Macintosh HD it does that same thing, goes to the "restart your computer" screen.
If I try to change the startup disk from the OS X Installation disk the only two volumes that show up are "Windows Vista on Untitled" and the "OS X Installation" disk, no Macintosh HD to even choose. I believe the reason for this is because Macintosh HD but as I have already said, it just can't be mounted.
I think the reason that Macintosh HD shows up when I press Option at startup is because Apple has hard-coded it in so that it's always there, no matter if you can actually access it or not depending on whether or not it's mounted.
Right now the best thing for me is to find out how to mount Macintosh HD, if it has to be done manually through Terminal I'll do it, I just need the syntax but something tells me if it doesn't work through GUI it probably won't work through command prompt.
Anyway, thanks for the reply. Let's hope we get something.

OSX Lion Disk Utility won't verify/repair RAID volumes

SInce I upgraded to Lion (now at 10.7.4) I can't use the Disk utility to verify or repair the disk catalog (disk first Aid) on apple soft RAID volumes. These volumes were created in 10.6 use the Apple RAID feature of disk utility.
I have one striped and one concatenated volume - neither will work. Press the button and the progress bar flashes for a fraction of a second, then nothing. no error, no message in the window - just no repsonse. Works fine on non raid volumes in the same disk enclosure -Firmtek Seritek/5PM, with seritek 2ME4-E sata card.
Not sure I really want to recreate and recopy the drives....
Any ideas? Seaches haven't turned up this specific issue.

A quick search in these forums for permissions or *permissions problem* reveals many posts the past four months.
In a nutshell, repairing permissions w/Leopard takes anywhere from 10-40 minutes, depending on what's installed and what's contained in /Library/Receipts/bom/. The repair permissions operation has changed in Leopard. The stalled progress bar is an unresolved bug (they haven't figured out how to make it work whilst it's checking or rebuilding the a.receiptdb, in /Library/Receipts/db/. To see what's really going on, open that folder in a Finder window, select list view, launch Disk Utility, select your boot volume, and click on repair permissions. Watch the Finder window flash files that are being read and checked against the current a.receiptdb file. That's what's taking all the time and freezing the progress bar. Once that's finished, the progress bar starts moving and the permissions are being checked and repaired. Also note, that you won't get any *they were repaired* message back for any that are noted to be incorrect.

Mounting Xserve Raid Volumes

I'm relatively new to Xserve RAID and I hope this isn't a topic that's already been covered.
If I unmount (or eject) a RAID volume, how do I re-mount it. Other than rebooting the system.
The RAID volumes don't appear in /etc/fstab. Where exactly does the system store the volume which are to be mounted at boot.
Thanks..

You might see the volumes in disk utility, and you can remount them from there.
Otherwise, you could unplug and re-plug the cable, and they'll show up, if you have physical access.

Disk Utility can see my drive but not mount/repair a volume on that drive.

Situation:
During a permissions repair on an external drive, the power went out.
Since then, it won't mount. It spins up, lights on etc, and the drive itself shows up in Disk Utility.
The volume is greyed out.
When I select the greyed out volume and select INFO, I get:
     OWNERS ENABLED: NO
     CAN TURN OWNERS OFF: YES
I would think it was a permissions issue since the power went off during repair, and I'm hoping to force-repair permissions.
Tried Disk Warrior (v 4.4)... it mounted but I got this message (despite hardware being fine):
          The directory cannot be rebuilt due to disk hardware failure (-36, 2747)
It's not a hardware issue; the drive is fine, it just won't mount.
What I've done:
Unplugged/replugged drive
Swapped out cables from a similar drive
Attempted Disk Utility on two laptops with same results
Booted from startup disk, ran DU, same results
Ran Disk Warrior
The only way to get the drive to show up in Disk Utility is to open DU, then plug in USB. It shows up every time, but once I attempt something, I have to pull/replug USB.
I cannot make a disk image in Disk Utility.
I have another completely empty 3TB drive that I could back everything up to.
Specs:
External drive, 3TB Western Digital, USB, HFS, no partitions.
Lion, 10.7.3
Mac Pro, 6GB memory, Intel processor
Drive name "WD My Book 1130 Media", Volume "Big Boy"
Suggestions?
Any force-repair terminal stuff?
Any software I'm not trying?
Any tricks?
Let me know if I'm missing some helpful info; I've done screenshots of every message screen; two are included below.
Thanks for any help!

Try this:
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select the desired hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

How can I rename a shared RAID volume?

I need to rename a shared RAID volume on OS X Server. What would be the best way to do this?
If the volume is renamed, will all the share settings need to redone?
It's currently "data RAID Set1" and I want it to be "data_RAID" or something with no spaces.

When you're on the page that shows all of your Pages documents that are stored in iCloud, simply click on the name of the file. You will be able to rename it from there.

Our XServe-RAID volume does not mount anymore...

Our XServe-RAID volume does not mount anymore.
On /var/log/system.log I could find the following.
Feb 22 09:52:29 ogre kernel: jnl: open: journal magic is bad (0xf433f != 0x4a4e4c78)
Feb 22 09:52:29 ogre kernel: hfs: early jnl init: failed to open/create the journal (retval 0).
It appears the the journaling is badly screwed.
I tryed to disable the journaling with no success.
Here is what I get.
ogre:/var/log root# diskutil disablejournal disk2s3
The selected journaling request does not appear to be valid
After some googling I foud this :
--- QUOTE ---
The more serious problem occurs when the contents of the journal file are corrupted in such a way that the operating system does not proceed to mount the volume. Fortunately, this problem is extremely rare (I have seen three reports of corrupted journal files at the MacFixIt Forums and Apple Discussion Forums since journaling was introduced).
Starting the journaling process is one of the first things that happens when a volume is recognized by the operating system. There appears to be no way to intervene in single-user mode before the journal file is examined. A message about �bad journal magic� appears. Unfortunately, every tool that can turn off journaling requires that the volume already be mounted.
If the Macintosh can boot under Mac OS 9, dealing with a corrupted journal file involves restarting under Mac OS 9 and using a utility (such as our free TechTool Lite 3.0.4) to make visible these two invisible files at the root level of the volume:
/.journal
/.journalinfoblock
Once these files are made visible, they can be deleted. Mac OS 9 does not support journaling, and recognizes nothing special about these files. Neither of these files can be seen in Terminal or in single-user mode in Mac OS X, because they are considered part of the disk directory.
If the Macintosh cannot boot under Mac OS 9, but the drive has Mac OS 9 drivers installed, the drive can be put into a Macintosh that can boot under Mac OS 9, or an ATA/IDE drive can be put into a suitable FireWire enclosure.
The possibility that you may need to remove these two journaling files under Mac OS 9 is a good reason for making sure that all volumes you use have Mac OS 9 drivers installed. The drivers must be installed when the drive is formatted.

XServe RAID volume does not mount

Without any modification to the system, a panic log from our XServe indicates:
"Thu Jan 18 17:28:58 2007
panic(cpu 0): HFS: corrupt VH on PBSRaid1, sig 0x4100, ver 0, blksize 0"
The volume PBSRaid1 does not mount anyway from that date.
Diskutil reports:
"Verifying volume “disk2s3”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid extent entry
The volume PBSRaid1 needs to be repaired.
Volume check failed."
DiskUtil is unable to repair the volume.
My configuration is:
XServe bi-G3 1GHz, MacOSX Server 10.3.9
XServe RAID with 5 disks RAID5 on the left side (OK) and 4 disks RAID5 on the right side (the bad volume)
All the controls are "green" and nothing wrong appeared in the events log obtained via RAID ADmin.
Any suggestion to repair are welcome, as we have many data from confocal microscopy on that volume.
Thanks

Right, Dave.
DW 4 rebuilt a preview folder which contains all the files in correctly named folders.Only 3 files among thousands has been saved in a Rescue folder !
It also restored the right volume label, lost in DiskUtil, fsck, pdisk and others.
Very nice tool.
While DW was building its preview, the disk 9 lighted red and a lot of failures of the controler 2 appear in the events log of the XServe RAID.
At this time, the RAID is rebuilding with our spare disk.
I think we have to change both the disk 9 and the controler 2 despite it lights green currently.

Erase and Install
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.

Any help here is appreciated

Unfortunately, I don't have a fix, but I have the same problem with a shared volume from OS X server. I have three copies of the volume 'Shared Files 2'. Two of the copies are there even when the volume is not mounted and the actual mount gets names 'Shared Files 2-2'. This causes some things not to work properly. For example, applications will not return to the previously selected directory on that volume. I noticed the duplicate soon after this problem began (when there was only one duplicate), and now there are two duplicates.

Xserve RAID volume corruption, volumes missing in Disk Utility

I have an Xserve with 3 drives in a RAID 5 set. The RAID set is divided into 2 volumes. After hard booting the server to recover from a crash, the volumes seemed to disappear.
We booted to an install disk and ran Disk Utility, which showed that there were no volumes at all. We then ran RAID Utility, which showed the volumes there.
After the RAID ran a re-initialization and verify, RAID Utility shows green lights throughout, as if everything is fine. Nothing else, however, can see the volumes.
We booted to an external drive with OS X installed, and basically found the same situation. Only RAID Utility can see those volumes, but otherwise they're just plain missing. However, RAID Utility does show "Partitions: None" for both of those volumes.
We have tried placing the drives into another server to determine if the problem is with the RAID card, but we had the same results. I also tried booting to target disk mode, but the other machine can't see the volumes all the same.
Using an external boot disk, we upgraded the RAID firmware. We also reset the SMC, as well as the PRAM. Nothing is working so far.
AppleCare basically told me that we're SOL and have to rebuild. Unfortunately, there is some data there which was overlooked in our backup procedure. If there is any possibility of recovering the data, I'd like to try it before giving up.
My absolute last option is to recreate the volumes exactly as they were before, then hope that I can use some manner of un-erase to recover the data. However, I'm not sure how RAID works on that level, should it just jumble the data, or if this is even remotely a feasible option.

Port 1: Link Established
2Gps
Point to point
Status light green
In the system Profiler I'm not sure what you're asking for, I'm running 10.5.8 standard not server.
the fibre channel shows link established 2Gps and cable type copper but nothing else, the disks & RAID controller don't show up anywhere I've looked.
RAID Admin shows the JBOD disks as online and lists the LUNs etc.
System looks fine, only error is missing second power supply.

Xraid - raid volume backup procedure question, need input...

If I have an xraid with two sets raid volumes, 2.5 TBs each, that I use for alternating backup. Am I eventually going to loose the fiber channel card, raid volumes, or xraid by switching out the raid volumes? I will have volume A in for a few weeks to a month then take out the drives/raid volume and put in volume B for about the same amount of time. I place the drives in the same spots/ side of the xraid. Each drive is labeled and place in the same spot each time. Everything has been working perfectly for a couple years but recently an apple specialist has told me that it's not a good idea. And that in time I am likely to damage/loose my fiber channel card, raid volume or xraid? That I am confusing the raid connection by changing drives.

Actually, this all started with our xserve failing. The hardware and procedures I put in place worked perfectly. The xraid backup etc. Retrospect did it's job also. we were able to recover everything now I'm looking to improve our downtime and put a new xserve in place. Retrospect apparently worked because it was on the xraid. The recovery from firewire drives as a backup system is low and painful and can there's also a chance that you have to rebuild the retrospect file. The apple certified folks were impressed, no issues. And I don't power it down that often, once a month average, maybe. What I do want to implement in retrospect is a working backup. Not that we will work off of it but if that was in place then we'd be up and running sooner.

Mounting xserver raid

Folks,
We have a xserve raid box set up and connected via fibre channel to a xserve box. What steps we need to do to mount the drives? What's the osx equivalent to vfstab and what device names reference them?
Powermac G5

That's exactly what you need to do. At this point they could be UFS, HFS or whatever you want. You need to partition and format them to your liking. Once they are formatted they will mount automatically on boot.
If you have more than one connected computer (or you use a fibre switch) you can use fstab to control mounting at boot time as per Unix regular usage. I have never been able to get an authoritative answer on whether Disk Utility honors fstab. I have a feeling it doesn't - or can be forced to override those settings - but I have tried it to see. Next time I take the servers down for back-up or maintenance I'll try it and see. I have 500GB of my 6 disk RAID5 carved out for my webserver - the rest of the side and the other side are for the fileserver - and I control their mounting with fstab settings. But I've never tried to forcibly mount the webserver volume on the fileserver.
Don't worry - the formatting is faster than than the initialization.
Good luck,

G5 doesn't mount Sata raid - hardware or (soft) data issue?

I had another thread going related to this. After much screwing around, here's my final question...
is it credible to think that a (Sonnet Tempo) card on a (late 2004 G5 PCI-X OS 10.4.9) would spew this error to the console (below) if there was merely corrupt data on the Sata raid. After problems mounting the atto striped drives - a new replacement enclosure worked out of the box twice, then not. Now nada & this error msg. When the raid volumes decide not to mount - no utility I own can see anything out there.
I'm almost ready to kiss my raid files goodbye but have this nagging feeling it's the port-multiplier encloure or compatibility issue and not the drives themselves because they came back to life for a while with the replacement Maxx Digital ro Raid II has a 936 Silicon Image chipset that stopped working.
Thanks,
Paul

earlier thread "disappearing SATA drives "

Hi Hatter - In Jan 07 the vendor Maxx Digital instructed me to use atto ExpressStripe. I'm not wedded to it except at this point that's how the drives with my valuable data happen to be striped. If I have to start over I'm sure I'd use SoftRAID or Apple RAID. Except for that legacy aspect, I've only mentioned atto ExpressStripe as one of two utilities I have that might "see" drives that don't mount (which they don't). I haven't tried DiskWarrior thinking it would not be any more likely to "see" the hardware.
DP even though other things are more suspect, I'm sending the Tempo sata card back to Sonnet for evaluation, repair/replace.
Thanks,
Paul
