Oddity when attempting to repair disk permissions...

I upgraded to Leopard recently and have been encountering some bizarre issues as of late. For one, it doesn't start up anywhere near as fast as it did when I first installed Leopard. And as far as the reason I'm posting this right now, all the Disk Utility processes seem to take a really long time, longer than usual. I'm running 10.5.2.
Per example, I verify my disk permissions, and it sits for at least 3-5 minutes with the progress bar locked at about 1/8th complete and the time remaining is indicated as less than one minute. Then it moves forward and completes the process in anywhere between another 3-5 minutes. The same occurs when I repair disk permissions or even verify the disk entirely.
Also, I'm getting the following log message. It's particularly weird because the exact same message shows up in the log after verifying and then repairing disk permissions, as if the repair process isn't actually repairing anything.
*Permissions differ on "private/var/log/secure.log", should be -rw-------, they are -rw-r-----.*
*ACL found but not expected on "Library".*
Again, this log message is displayed after completing each process. Quite odd... any thoughts? Please advise! Thanks in advance.

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.

  • Disk Utility hangs ("not responding") when attempting to Repair Disk on Time Capsule sparsebundle.  Help.

    I am trying to improve the performance of my Time Machine backup and retrievals via my 2nd Gen. Time Capsule from my iMac Core 2 Duo hard drive with SL 10.6.8.  The incremental backups generally take 20 - 40 minutes each hour generally with fewer than 100 MB of data being backed up.  I have read through numerous threads on these forums about Time Capsule and Time Machine issues as well as the very helpful Pondini site (http://web.me.com/pondini/Time_Machine/Home.html) and have tried many other suggestions (listed below), but have been unable to attempt a Disk Utility repair disk on the Time Capsule sparsebundle file.
    After locating the sparsebundle 'file' in the finder under Shared/TC/Data, I am only sometimes able to drag the sparsebundle into the Disk Utility volumes and disk window.  About fifty percent of the time, Disk Utility hangs when attempting to drag in the sparsebundle.  If I am able to get it listed and click on "repair disk", then the beach ball begins to spin and nothing happens.  This occurs whether or not I first use AirPort Utility to "Disconnect All Users" from the Time Capsule.  I have given it over one hour to attempt the repair disk, but nothing happens, i.e., not a single message shows up in the detail window.  The beach ball just spins, and Disk Utility shows up in red as "not responding" under the Force Quit menu.
    Also note that on my new Macbook Air, Time Machine runs quite quickly via this same Time Capsule from my new Macbook Air using OS X Lion (which seems to indicate that the Time Capsule drive itself is OK).
    I would appreciate any tips on getting Disk Utility to run "repair disk" on my sparsebundle, as I seem to have exhausted most other options (see below) for improving Time Capsule performance -- aside of course, from wiping the Time Capsule clean and starting all over.... (which I really don't want to do, and from what I've read, has not helped some people who've tried this anyway).
    Many thanks!
    Although I would like to focus this thread on the Disk Utility / sparsebundle "Repair Disk" problem, I should mention that I have tried the following other things:
    1.  Repaired disk permissions on my hard drive
    2.  Used Disk Utility to run "repair disk" on my hard drive after starting up from a SuperDuper external backup
    3.  Run DiskWarrior on my hard drive, again, from a separate startup disk
    4.  Did the "full reset of Time Machine", a la Pondini Troubleshooting #A4
    5.  Changed my computer and Time Capsule names to simple short names with only alphanumeric characters and no spaces
    6.  Ensured that my Time Capsule is being accessed only via ethernet
    7.  Relaunched the finder
    8.  And finally, attempting to use Disk Utility to repair the sparsebundle - thus the nature of this post

    OK, no takers out there, but I answered my own question (sort of).
    The answer is that even though Disk Utility shows up as "not responding" under the Force Quit menu and appears to hang, it is actually still working.  A bit of patience shows that after about an hour, my Disk Utility was able to show the 1.44 TB Time Machine sparsebundle from Time Capsule in the disk window on the left hand side.  Once this appeared, I was able to click on "Repair Disk" (note that prior to doing this, I had to "Disconnect All Users" from my Time Capsule using the Airport Utility program; otherwise you will get a "could not unmount disk" error).  Again, the Repair Disk function appeared to hang Disk Utility as it showed up as "not responding" under the Force Quit menu.  However, after about 8 hours, Disk Utility did run the entire Repair Disk protocol on the sparsebundle.  The results DO NOT show up in the Disk Utility details window - so even if you are patient enough to let it complete, you will not see anything and may think that nothing happened.  However, you can find the familiar results of the Repair Disk function by looking on Console - find the "DiskUtility.log" under Files: ˜/Library/Logs.
    Unfortunately, I was hoping to find a problem that would have been subsequently repaired which would result in dramatically increased Time Capsule speed, but this was not the case.  Disk Utility showed everything to be "OK" and I am stuck with a very slow Time Capsule....
    (And of note, my new Macbook Air (OS Lion) Time Machine functions blazingly fast on both backup and retrieval to and from the very same Time Capsule - even though, these are occuring wirelessly via AirPort -- granted the size of this sparsebundle is an order of magnitude smaller at this point, i.e., only 10 GB right now)
    Would still be happy to hear of any similar experiences or tips on getting Time Capsule to work more quickly.

  • When repairing disk permissions today I got a new warning message . . .

  • Repair Disk Permissions Error: The underlying task reported failure on exit

    Hi All...
    any idea about this error when trying to Repair Disk Permissions using "Disk Utility" :
    "Error: The underlying task reported failure on exit."
    No repair is made at all! It just stops right after being launched
    It happens either when booting on the Leopard CD or on external FW drive...
    Cheers guys!!

    Someone help!!!
    It sounds as if you transferred the errors when you migrated your files from the G4. Something in that old filestructure that is not right. It might be the ownership of a single file somewhere.
    Have you considered DiskWarrior?

  • "Repair Disk Permissions" keeps showing the same permission differences

    After the recent software updates, I suddenly cannot use my eFax Messenger. This happened once before, but I was able to fix the problem by running "Repair Disk Permissions" in Disk Utility.
    This time "Repair Disk Permissions" did not fix the problem. Not only that, I noticed the same permission differences showing up again and again when I repeated Repair Disk Permissions.
    Is the permissions database no longer accurate? Does anyone have any suggestions on how to resolve the permission differences? I notice that others have reported similar issues on this forum, but no definite resolutions have been posted.
    Thanks for any help you can give me.

    ..."As long as the repair ends up with the message 'repairs complete' or words to that effect, you are OK."...
    I don't know who started with the "repairs complete means everything is fine" business, but they were wrong and it is repeated far too often by too many people on this site.
    Considering all of the messages erroneously being dismissed as "informational", it is ironic that the one message that is actually just "informational" is the one being given special significance.
    The "repairs complete" message only means that the process has stopped. Try starting to repair permissions, then immediately click the "Stop permissions repair" button. Try logging in to a non-admin account and start a run -- when a password is requested, cancel. Try repairing permissions when there are problems with the permissions database. You will see messages such as "Stopped by user", "insufficient privileges" or "underlying task reported failure on exit, but in every case, the report will end with the "Permissions repair complete" message.
    With respect to the OP's question, the overall "repair permissions" system as it stands in 10.5 has the appearance of an unfinished product (it received major revisions in the transition from 10.4). Without specific details, all anyone can say is that the error messages are likely false positives - except for any true positives that might be present among them.

  • Repair Disk Permissions disconnect

    My G5 is used as a stand-alone video editing system. Whenever I attempt to Repair Disk Permissions on my MAC drive (whether in Normal or Safe mode) I get about a third way into the program and then get an alert message telling me that the disk utility has lost its connection with the Disk Manager. Disk Warrior software does not resolve this problem. Is this a hardware or software problem? What should be my next step? Please advise.

    There is a fix for something similar at the link here

  • Trying to install Lion. says this disk is not enabled (journaled) - but when I look at the drive it actually is os extended journaled - Stuck! Have tried repair disk permissions and still no luck

    trying to install Lion. says this disk is not enabled (journaled) - but when I look at the drive it actually is os extended journaled - Stuck! Have tried repair disk permissions and still no luck - any thoughts? Have spent two weeks trying to get apple support and itunes to help me get lion after a hard drive fail and now they are closed and I really just want to get moving!

    Are you installing OS X Lion over an existing installation of Snow Leopard, or are you reinstalling?
    First be sure you have everything on your system backed up. Then reboot with the Command-R keys held to get to the OS X Lion recovery volume. In here, select Disk Utility and use the First Aid tab in here to run a verification on your boot drive. If there are any errors, fix them and then try the installation again.
    The next step would be to format the drive, so with your backup secured, use Disk Utility's Erase tab to re-format the drive to Mac OS X Extended (journaled), and then quit Disk Utilty and attempt the installation again.

  • Disk utility errored out when attempting to repair Macintosh HD

    My iMac suddenly got really slow this morning, occasionally freezing for a few minutes. I ran disk utility to repair permissions, MacJanitor and then restarted to no avail. Then I started up using the original install CD (10.4.4), ran the hardware test and passed, and attempted to repair the disk with Disk Utility. I got through the first steps, but then when checking the Catalog File, I got the following error:
    Invalid Node Structure
    Volume Check Failed
    Error: Underlying task reported failure on exit.
    Before I exited, I repaired disk permissions again, and this time it found a bunch of bad permissions...when I restarted, system was still slow, so I know I still have a problem
    Any suggestions on what to do next?
    Thanks,
    Eric

    Try that disk repair a few more times, you never know!
    But more then likely it won't be able to repair an Invalid Node Structure. That's a pretty serious error.
    If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy. Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
    I use DW once a month to try and catch errors in my system from getting too far out of hand.
    If you have a good backup, hopefully a clone of your system before you had issues, an Erase and Install will also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!
    Cheers! DALE

    Try to put your headphones several times in and out from your connection, might be the switch is stuck. Normally it should work again while trying to plug the headphones in and out!

    > I repair permissions using the Tiger disc upgrade.
    One thing to note...  When running Repair Disk Permissions, it is best to run it while started up normally, from your normal startup disk, not from a Mac OS X installation disc.  The only time you should run it while started up from an installation disc is if some problem is preventing you from starting up normally. OTOH, Repair Disk can only be used when starting up from a different disk (such as an installation disc).
    So, I would start up normally, run Disk Utility, and use Repair Disk Permissions on your normal startup disk.
    NOTE:  Repair Disk Permissions often gives alerts messages that can be ignored.  They are more "informational," not serious errors.
    http://support.apple.com/kb/TS1448
    You should still run it periodically.  When you run it, what needs to be repaired has been repaired; consider the rest of it an FYI.  I've never experience a problem, where a Repair Disk Permissions message actually caused a problem.  But, if you ever get an error while running Repair Disk (or Verify Disk), that is usually a serious problem.

  • When run repair disk permissions?

    I am going to upgrade from Snow Leopard to Mountain Lion.
    I have heard/read that you're supposed to run repair disk permissions beforehand. 
    1.  Should I run repair disk permissions on my brand new backup disk (am planning to backup Snow Leopard and all apps and docs before upgrading to Mountain Lion - - so can restore Snow Leopard etc. if want/need to)?  If so, do I run repair disk permissions on the new backup disk before or after I partition the backup disk [am planning to have two sections, one with all the Snow Leopard stuff, and one for iMac backups that will be made after have upgraded to Mountain Lion])
    2.  When's the best time to run repair disk permissions on my iMac - - before I download Mountain Lion or right before I do the installation of Mountain Lion?
    Thanks.

    It's not a requirement, but it may help especially if you don't attend to the state of your running OS. I recommend doing this:
    Repair the Hard Drive and Permissions
    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. After DU loads select your 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Then you can proceed to click on the Install button after the upgrade finishes downloading. I also suggest you make a bootable backup of your current Snow Leopard system on an external drive just in case things go badly.
