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.

    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.

  • 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.

  • 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.

  • 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,

  • Xserve RAID volume maintenance

    A new client has an Xserve RAID (firmware 1.5) in which the first 7 drive modules are populated, and configured into a 1.01 TB Level 5 array. This array has been in use for (estimated) 2.5 to 3 years (based on the power-on hours of the component hard drives). As far as my client knows, no maintenance has been performed on the RAID volume. Should we be using the First Aid feature of Disk Utiliity or something like Disk Warrior on this volume? The Xserve RAID is connected (via Fiber) to a Power Mac G4 (Mirrored Drive Doors) running Mac OS X Server 10.3.9. Please advise.

    Are they having problems with the RAID that you think requires maintenance?
    FWIW I've got several XServe RAIDs in my network, some of them the same age as this one, and I've never done anything to it in terms of maintenance or housekeeping.
    If you're not having problems with it, I wouldn't worry.

  • XServe Raid volume corruption

    Hi peoples, My RAID volume has corruption and I have had trouble making an image using Disk Utility. I finally completed what looks like a good copy using sudo ditto -V /Volumes/data/ /Volumes/1TB/
    I am about to destroy the RAID and recreate but before I do I want to ask your opinion on a strange size difference between the source and the destination. The destination has a larger more realistic size than the source when I Get Info on the folders. Is this a symptom of a dodgy volume?

    You've likely already took the plunge, but Get Info does not always tell the whole truth when selecting a set of folders. This is a cause of permissions. To get an accurate comparison, use sudo du -H /path/to/source and sudo du -h /path/to/destination. This ensures you will read every file. Also, du will report all files so if you capture the output you can diff the result of both to see if there is discrepancy.
    Hope this helps. Good luck with the volume.

  • 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.

  • Volumes folder on my xserve raid

    Hey all!
    When my network users login, they can see the root level of my xserve raid. Shouldn't this ve hidden?
    What if someone decides to trash my Volumes folder or decides to make any folder they want?
    When I try to disable sharing on the root level, of course, the subfolders are inacessible?
    Any advice, please?

    I assume you mean when your network users log into their workstations they mount the XServe RAID volume shared via some host on the network, right?
    If that's the case your solution is to just change the sharepoints on the server to share subdirectories on the XServe RAID rather than the entire RAID.
    Use Workgroup Manager to designate other sharepoints on the server. You'd need to look at how the clients are mounting the RAID in order to determine what changes you need to make there.
    BTW you can't delete the /Volumes directory, so don't worry about that part.

  • XServe RAID firmware upgrade - ASCII identifier

    Got called into a situation where files & folders stored on an XServe RAID were disappearing and appearing randomly, not only from the client standpoint, but while looking at the XServe RAID volume on the XServe, as well.
    Turned out to be file system corruption that Disk Utility couldn't repair. DiskWarrior seemingly was able to fix it. Ran Disk Utility afterward and it reported no errors. And all the files and folders appear to be there (from the XServe).
    However, now the problem is that when a user mounts the main sharepoint, she can only see 15 of the 37 folders. Other sharepoints only show a fraction of the number of "real" folders that should be there. The folders that are missing are at the end of the list alphabetically. Logging in as admin user shows the same behavior.
    Redid permissions with Workgroup Manager. No help.
    My suspicion is that it may have something to do with the RAID controller firmware. They been running with RAID Admin tools 1.3.2 since it came out, and everything has been fine. However, everywhere I've read emphasizes how important it is it keep the RAID controller firmware updated.
    The reason they haven't updated the firmware (to 1.3.2-1.26) is that the Sys Admin there believes that it will mess up the half of the XServe RAID that is serving a Windows 2003 server (his baby). The specific line that terrifies him is:
    "- INQUIRY page 0x83 response ASCII Identifier string cleaned up and Identifier EUI-64 replaced with NAA-64"
    I just don't have enough server experience to know what that means, nor have my online searches turned up anything.
    Can anyone explain what the ramifications of this sentence from the ReadMe are? Is there any reason to suspect that after the firmware upgrade, the Windows server will no longer recognize it's half of the XServe RAID?

    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.

  • Can't enable ACLs on a RAID volume

    Hi all,
    I have OSX 10.4.11 running on an Xserve G5 ppc. There are 2 Xserve RAID volumes attached by fibre channel.
    I've been having issues recently with permissions: some users are creating or modifying files/folders and other users in the same group are then unable to access them. Viewing the permissions shows that group access is set to 'None'. I can correct this in the 'Sharing' section of WGM but that doesn't resolve the underlying issue.
    I want to use ACLs to control access to data on the 2 RAID volumes, one of which also contains the users' network accounts. Unfortunately the 'Enable Access Control Lists' tick box is greyed out so I cannot activate them. On the other RAID volume all three tick boxes are available.
    Why might this be?
    John.

    Found the answer. The volume was not correctly formatted. I copied the data, reformatted the volume, copied back the data and enabled ACLs.

  • To Xsan or not to Xsan... bunch of Xserve raids + fibre switch

    Hi all,
    I have 4 Xserve Raids and a fully licensed Qlogic switch plus an Intel Xserve to share it all.
    I went ahead and loaded Lion Server on my Xserve for the "free" Xsan which is shweet but was pondering wether I need the overhead of the Xsan?
    My need is just a simple NFS share, nothing fancy.
    I was thinking to share 1 Xserve Raid as a volume (striping 2 sides together) and serve the other 3 as another volume (striping 6 sides together).
    Any nuggets of wisdom are very much appreciated.
    Thanks in advance,
    - Brian

    There's nothing in your post that implies XSAN is needed.
    XSAN is needed if you want to connect multiple hosts to the fiber channel network - in effect, giving each host direct access to the XServe RAIDs.
    Since you stated you want '... a simple NFS share', that implies that the host XServe is sharing the XServe  RAID volumes over the network, therefore XSAN isn't required.
    You might get better performance by connecting the clients to the fiber channel SAN, but it doesn't sound like an issue for you.

  • Cannot map or even see drives on xserve RAID hanging off a xserve

    Sorry if I sound like a complete idiot, but when it comes to Macs I am one. We have a OS X Server 10.5.8 and a xserve RAID. The RAID looks ok and under the server I can see both of the RAID drives that have been created and access them. When we try to map to it on one of our house Macs, its errors out with "There was a problem connecting to the server." When we try to map to just the root of the server, we can see its hard drive, but not the RAID drives. Any help would be most appreciated!

    By default, Mac OS X Server only shares the root drive.
    In order to share external volumes (such as the XServe RAID volumes) you need to use Server Admin to mark the volumes as shared (as well as which protocols to use).

  • Xserve RAID and windows

    How do I configure a Windows PC to access Xserve RAID drives?

    Kind of a vague question...
    Are you trying to attach the Windows PC directly to the XServe RAID?
    Or is the XServe RAID attached to a Mac and you're trying to access the data over a network?
    In the first case you should just need a fiber channel card in the Windows PC and run a fiber channel cable from the PC to the RAID - depending on how the RAID is configured, it should just appear.
    In the second case you need to share the XServe RAID volumes via SMB. The specifics of how to do this vary based on which version of Mac OS X Server you're running.

    Does it see the drives? a RAID set on those drives? A link on the fiber channel connection?
