Filesystem won't mount in rc.sysinit

My RAID card won't mount with the other filesystems in rc.sysinit, it displays
mount: special device /dev/sda1 does not exist.
However, I took it out of fstab and added the line
mount -t reiserfs /dev/sda1 /var/lib/mysql
to rc.multi, so it mounts the filesystem right before it starts the mysql daemon, and it works just fine.
Any ideas as to what would cause this?

Hi Olaf,
No, it hasn't gone away. I only have those two iPod menu items: HDSpecs and HDSMARTData.
But I don't think there's anything wrong with the iPod; it works on other machines. And no other iOS devices will work on this Mac; I've tried an iPad and an iPhone. I spent 20 minutes on the Apple support chat yesterday. They suggested I zap the NVRAM and the SMC but I've tried both of those. They gave up after that and suggested it was something to do with the Mac's logic board or power management chip. But that doesn't explain why it works perfectly well with my Android phone and my Kindle.
I don't want to take it in and find out the logic board is failing, so I'm just going to have to carry on listening to old music on my iPod, and never buy an iPad or iPhone!

  • SAN filesystems won't mount at reboot

    We are seeing a problem with Redhat Linux AS 3 (update 4). We have some filesystems on SAN and they won't mount at reboot. We have to exclusively probe the module interface for SAN and then mount the filesystems. In one situation, we have Q-Logic interface for the SAN, and we do “modprobe qla2300” before we attempt to mount. There are other situations now where we have Hitachi SAN. The sequence is, do a mod probe for SAN, mount the SAN file systems, and then start all apps needed on those filesystems.
    The problem is where to insert such commands in the boot sequence. The rc scripts won’t help as they get kicked off after filesystems mount. Because the filesystems don’t mount, all actions we want from boot on startup would fail.
    Anyone faced this kind of problem? Appreciate your feedback and any work-around you used.

    ... and we do “modprobe qla2300” before we attempt to mount.Question is why don't you using /etc/modprobe.conf (modules.conf in earlier linux versions)? Simply you configure modules.conf and Qlogic module will be loaded up automaticaly.
    Example of modprobe.conf for qla2300:
    alias scsi_hostadapter0 qla2300_conf
    alias scsi_hostadapter1 qla2300
    alias scsi_hostadapter2 qla2300_conf
    alias scsi_hostadapter3 qla2300
    post-remove qla2300 rmmod qla2300_conf
    options qla2300 ql2xuseextopts=1
    post-remove qla2200 rmmod qla2200_conf
    The sequence is, do a mod probe for SAN, mount the SAN file systems, and then start all apps needed on those filesystems.Again, load modules automaticaly via modprobe.conf.
    The problem is where to insert such commands in the boot sequence.For automatic mounting you could use automount for example. Of course you must have all relevant modules loaded (see modprobe.conf).
    Other scripts belongs to rc definitely.
    The rc scripts won’t help as they get kicked off after filesystems mount. Because the filesystems don’t mount.Why FS don't mount? Some error message?

  • Firewire hard drive won't mount - Filesystem verify or repair failed.

    Hi all - over the last day my lacie hard drive won't mount - i have tried it on various computers with the same result
    disk utility can see it but won't mount or repair it reporting the following error
    Filesystem verify or repair failed.
    any help would be appreciated

    Try Disk Utility first. It's in your Applications/Utilities folder.
    You'll want to select the disk in question, then +Repair Disk+ (not Permissions). This actually repairs the +File System+ that's on the disk.
    If that works, you're ok, unless it begins happening frequently. Then you need to save up for a new one.
    If DU can't fix it, then one of the others might. Disk Warrior is about $100, and many people here say it's the best. There are others for less money, but there's no guarantee that any of them will succeed.
    You can also try just erasing it, and choose +Security Options,+ then +Zero Out Data.+ If that fails, or you have more problems with the drive, you need a new one.

  • Upgraded to Mavericks. Now External HDD Enclosure Won't Mount. Is there a fix?

    Upgraded to Mavericks.  Now I can't get my external HDD enclosure to mount.  A little about this enclosure, as it's not the usual settup .  I have four 3TB HDDs in a RAID5 settup.  The most unique part is that they are formatted as a Windows NT Filesystem (Tuxera NTFS).  Basically, when I set this up, I had to get a lot of info from a Windows-formatted HDD, but also be able to read/write afterwards. It's worked fine for ~ 1 year, but now that I've upgraded to Mavericks, nothing will mount.  I ran Disk Utility, where I see the HDDs (I've partitioned them into four drives of varying sizes), but they are greyed out.  I tried to mount them, but it says it won't and that I should run First Aid.  So I did...tried to "Repair Disk," but it just gets stuck on "Updating boot support partitions for the volume as required."  For over an hour it's been on that message.
    So, does anybody out there have a fix?  I've read several similar posts about people having a hard time mounting and, overall, dealing with external HDDs after upgrading to Mavericks.  But nothing seemed to fit my exact circumstances.  Lastly, I should mention that I've used both Firewire and USB connections.  Both resulted in the same.
    Thanks.

    I can't help with specifics for your issue, but some general thoughts:
    The upgrade and the disk problem may be a coincidence. It would help you if you could verify that the drive still works fine on a windows machine. If you run a windows virtual machine or have a windows pc, or a friend does, verify full functioning that way. If it still won't mount on the mac, try to copy/backup it's data onto the windows machine (maybe another external drive connected to it. You could then scrub the disk in windows, leave it unpartitioned, unformatted. Connect it back to the mac and format it as HFS+ (Mac extended journalled) and transfer the data back to it by sharing the windows machine external drive and connecting the two machines with a network cable.

  • External Hard Drive won't mount - tried Disk Warrior, am backing up as a .dmg...will this work?

    Hi Guys,
    Hopefully someone can help! Fairly desperate situation here...
    I backed up around 700GB of data to an Iomega external hard drive (supplied by the client), using my Macbook Pro...all was fine when I unmounted the drive at the end of the backup.
    The client took the drive away and called me to say he mounted the drive in Windows (on a PC), and he was able to work with the files for a time, but now the drive won't mount...
    I collected the drive, hooked it up to my Mac Pro, but OSX tells me it can't mount the drive. It shows up in Disk Utility in the sidebar, but not on the desktop...
    I tried repairing the disk using Disk Utility and with Disk Warrior, both tell me the disk cannot be repaired...
    I am currently making a backup of the drive as a .dmg file, using a program called Disk Drill...it's slow as I expected, but I'm still not sure the .dmg will mount...because surely it's just making a copy of the data exactly, of which some part is not mounting (a mount directory or something???)
    Is there any way you guys can think of me somehow taking the data and backing it up onto another disk?
    Specialist recovery services seem to think there shouldn't be any problem recovering the data, and of couse, as a costly last resort, that's what I'll have to do, but does anyone know how they may go about doing it? It is something vastly complicated such as a command line thing?
    Sorry about the length of this question...just hope someone can help!
    Thanks in advance...

    You didn't say what format (filesystem type) the disk was.
    However, I'd say your analysis is probably correct. Something has corrupted the disk. You can make a disk image copy to the .dmg which will preserve the data, such as it is, but I doubt extremely if it will fix any file system corruption.
    Furthermore, if both Disk Utility and Disk Warrior have said the disk is unreadable I'm dubious that anything else will magically repair it and that recovery probably consists of snuffling through the disk block by block.
    However if the filesystem is FAT (Windows) there may be other (Windows) utilities that can fix it.
    You said you 'backed up the data'. Does that mean you still have the original data on your MBP? Are you trying to recover the client's changes?

  • External HD Won't Mount - Force Ejected it and now won't mount

    Hi All,
    I seem to remember this happening to me before. Isn't there somewhere in the filesystem that OSX writes a file if a drive was mounted? And if you ejected a USB disk incorrectly, it cannot ever mount again?
    I can't seem to find that fix anywhere.
    ANYWAY, my problem is this. My TimeMachine backup disk (Western Digital (WD) 500 GB MyBook) won't mount (attached via USB). It doesn't show up in the Finder. It DOES show up in Disk Utility but when I click Repair Disk it promptly says:
    "Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
    I really don't think the disk is fried. I think there is just something keeping it from being mounted. I could be wrong.
    Any ideas? Thanks in advance. Struggling with this waaay too late on a Sunday night.

  • External disk won't mount after 10.5.7 upgrade

    Hi,
    I know there's problem with Buffalo external HD; mine is Lexcron 3.5'' external case and it won't mount neither. I tried PRAM restart, and if I go to Disk Utility and try to repair, it gives me the following message:
    Verify and Repair volume “Dirty Hary”
    ** /usr/local/bin/ntfsfix has been disabled because of volume corruption issues.
    ** If you still want to try fixing your volume, use /usr/local/bin/ntfsfix from the command line...
    Error: Filesystem verify or repair failed.
    It worked with 10.5.6 and it still works with Win XP (it's NTFS format).
    Is there something that I can do?
    Will this issue be solved in Snow Leopard?
    Thanks in advance for any kind of constructive info (I've already read threads with Buffalo issue, but I didn't find any thread giving a solution).

    Hi V.K.,
    Thanks for your response, can you provide some more details?
    OS X has very limited support for NTFS. you need to repair the drive from windows.
    How do I do that? I mean the disk works normally in Win XP and it worked normally in the previous OS X version. Btw. I've also installed NTFS-3D which allowed to write on the disk and search from spotlight (of course when it was mounted).
    run chkdsk in windows and see if it finds any errors.
    http://support.microsoft.com/kb/315265
    it can also be that the problem is caused by ntfs-3g which is known to have a number of bugs. you can try uninstalling it or plugging in the drive in a mac without ntfs-3g installed.
    there is no "issue" to solve.
    Well if it worked in 10.5.6 and it works in Win XP and it doesn't work in 10.5.7 I am tempted to say 10.5.7 has an issue.
    the fact that you have a problem with one drive on your particular system doesn't mean there is a problem with os x in general. an issue is when all or at least many people have a problem, not one.
    furthermore, NTFS is a proprietary file system of Microsoft with closely guarded secrets about its inner workings which is why it has very limited support on other types of operating systems. apple is under no obligation to provide ANY support for something like that. programs like NTFS-3g are essentially unauthorized hacks.

  • DVD+R DL won't mount...on 3 different drives!

    Yikes!....Help!...I'm really stuck....
    I've read a lot of the posts here regarding DVD's that won't mount and thanks in advance to those who've offered help. Hope you have some suggestions for me. Here's the deal.
    About 4 months ago, the disk, a Memorex DVD+R DL, was successfully burned on my G5, using 10.4.11 for burning. And I was able to mount and read it a couple of times. It's a data-only archive disk of old files.
    Over the past month, I've acquired a MacPro 2.8G 8-core (10.5.6) and a MacBookPro 2.61G Core Duo (10.4.11). And this disk will not mount on any of these 3 machines...not the MPro, not the MBPro and not the G5 that it was originally burned on! All 3 machines yield the same result...they kick the disk back out with out any messages..."error" or otherwise. There doesn't appear to be any significant scratching or degradation on the disk.
    I've searched the net for a "Mac DVD data recovery" program but;(a.) haven't been able to find one....they're all PC and (b.)don't really see how any software app could "deal" with a disk that won't even mount!
    I've had a look at the "upgrade the firmware" options, but it would seem strange that the firmware would be the problem on all 3 different drives.
    I'm down to contacting a Pro Data Recovery company, but that'll be expensive!
    So any and all suggestions will be HUGELY appreciated!
    thanks,
    b myers

    The usual problem with Memorex DVD's of any format was they didn't burn period, so well done getting one to burn, AND a DL no less. I would try an external DVD burner from LaCie (or LG which makes a good USB one), or even a Windows box to see if anything can read it. A PC with EZ CD Creator or Nero could image and burn on a decent brand of DL (e.g. Verbatim) or even a USB drive.
    Cheaper alternative is a 2nd non identical brand drive in the mac Pro, as they do take two.
    Diskwarrior is not an option for something that isn't seen and thus is unable to be mounted by the filesystem.

  • How can I change filesystem check bahaviour in /etc/rc.sysinit?

    Every time I boot my system, my filesystem is checked. Since it takes some time, I decided to change the /etc/rc.sysinit script so the filesystem check is performed every 100 boots (or once a month). I wanted to save the needed data ("boots counter" and the last filesystem check date) to a file placed in /var, but I got some error message saying that the / filesystem has been mounted read-only.
    Where can I store such information?

    actually, the last number in fstab controls that.
    0 - no checks performed
    1 - checked in first round (use for root)
    2 - checked in second round (use for other partitions)
    linux fstab manpage wrote:The sixth field, (fs_passno), is used by the fsck(8) program to determine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. Filesystems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked.

  • Bootpartition won't mount, fsck finds no errors

    Hi guys,
    got a strange situation here. My Bootpartition /dev/sda2 won't mount in Arch anymore.
    mount /dev/sda2:

    missing codepage or helper program, or other error

    The same error appers during boot. I don't know how Arch can boot without bootpartition but ist does...
    Another strange thing is that it mounts fine in Mandriva running on the same machine. Also testdisk under Windows didn't complain.
    dmesg | tail

    So what now? Any help is appreciated.

    no changes to any partitions were made, just did a fatal "pacman -Syu"...
    i removed the /boot completely from fstab and tried to mount the partition manually.
    i also recreated the whole partition under ubuntu. copied the files out, deleted the entire partition, recreated it and copied the files back.
    arch linux still can't mount it.
    also when i'm trying to mount my jfs partition, the "mount" command hangs completely. even "kill -SIGKILL $pid" can't get rid of it.
    the jfs partition also mounts fine under ubuntu, i ran tests on every partition under ubuntu, they're all clean.
    mounting an jfs partition don't give any logfile entry, dmesg is also empty. it's just hanging. the funny thing is, that ext4 and vfat partitions are mounting fine.
    could something be wrong with hal or dbus?
    here's e2fsck output:

    --------EDIT:
    finally found it!
    for some reason (i don't know why) the /boot partition was not mounted during update and thus the kernel26 image was written into the /boot directory of the root partition instead of the /boot partition (where it belongs). this means on next bootup the system was booting with the older kernel but the updated system. maybe some things in filesystem handling were changed between the two versions of the kernel.
    i mounted the arch partitions within ubuntu and copied the files from the /boot directory to the partition which should be mounted in /boot on startup.
    everything's working now.

  • Drive Visible Thru diskutil list But Won't Mount

    I'm attempting to recover information on a hard drive that won't mount. I can see it in Disk Utility and through the Terminal, but everything I do to access the drive contents is met with some sort of roadblock. Here are a couple of things I tried:
    sudo diskutil mount disk3s10
    ... results in "unknown special file or filesystem
    sudo diskutil mount disk3s10
    ... results in Unrecognized filesystem
    sudo dd bs=512 if=/dev/disk3s10 of=/dev/disk2[location]/recovered.dmg conv=noerror,sync
    ... results in Permission denied
    Using Disk Utility (through the Finder) I can "see" the drive and Verify/Repair the disk.
    ... The volume External FW -150GB appears to be OK.
    Also in Disk Utility, when attempting to mount,
    ... The disk "External FW -150GB" could not be mounted. Try running Frist Aid on the disk and then retry mounting.
    Ideally I could get the drive to mount. But short of that I'd be incredibly happy copying the data to a disk image and pulling out whatever still appears to be intact. If anyone has ideas what to try next I'd really appreciate the direction. Thanks.

    Hi
    Possibly a fault on the drive controller card? Mechanically it seems OK because at least you can see it in DU and it does seem to be spinning.
    In cases like this I have used DataRescue:
    http://www.prosofteng.com/
    With some success. DataRescue can scavenge for data without the need for a valid directory. As long as the drive is spinning you stand a chance. Might be worth a shot?
    If you have DiskWarrior you could use that? Sometimes it can restore/replace a directory for long enough to allow you to get desired data off it. If it can manage it then the drive should mount. You will have to be quick though as you will probably only get one chance at it.

  • Can't install Snow Leopard on MacBook Pro - DVD won't mount

    I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount.  This is an early 2008 vintage MacBook Pro, intel core duo...
    I'm using a OS X Snow Leopard install DVD (family licensed).  This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP.  Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted.  Upon running the installed (a year ago), the computer restarted but hung in boot.  After getting the disk ejected and the computer restarted, the disk would never mount again.  I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
    The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
    BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs.  Only the Snow Leopard install DVDs fail to mount.
    I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing.  I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
    I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
    Zapping the PRAM did not help.
    Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

    Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

  • Thunderbolt external SSD won't mount

    I'm using the Elgato Thunderbolt SSD as an external hard disk with my 2013 MBP. Since I'm also using a Thunderbolt display, I usually daisy-chain the disk to the display.
    Recently I disconnected the Thunderbolt display from my computer without unmounting the external SSD. Since this also disconnected the disk, I got the usual ticking-off ("You should eject a disk before disconnecting it").
    However... since then, the external disk won't mount. It doesn't show up on the desktop or in Disk Utility, though it DOES show up ("Thunderbolt SSD") in System Information.
    Because the SSD gets warm when it's in use, I think it's still working. I just can't access it.
    Can anyone help?

    Is the Apple Thunderbolt Display at the END of the daisy-chain? That's where it should be - all other TB devices should be connected first, with the Display at the end of the chain.
    As to why you're having a problem getting the TB SSD to work, I'm stumped. It seems as if you've done everything that I would try to do to get everything working... and I'm assuming that you have powered down and unplugged the Display and all other devices for 15 minutes or so?
    Just make sure that the Display is at the end of the TB chain - that's really the only advice that I can offer.
