Mac Forum / General / General / June 2007help: RAID1 on MacPro, Disk First Aid failed
I have a MacPro with a RAID1 disk (2x750GB Seagate). Lately it had difficulty starting up, later announced it would rebuild one slice of the RAID1. Then it did not start up. I did a repair permissions, worked ok. After that started up with installation disk and fired up Disk Utility. First run: extent allocation wrong, etc. Currently it does return this when run: --- Invalid extent entry Incorrect block count for file dup-i.yami (It should be 1 instead of 4194305) Overlapped node allocation Volume check failed Error: The underlying task reported failure on exit. 1 HFS volume checked 1 volume could not be repaired because of an error First Aid failied --- (Seagate ST3750540NS media, SMART status verified Mirrored RAID Set, RAID Status Online, 2 slices) What can I do? TIA Marc (Desperately hoping for ZFS in Leopard ...)

Try DiskWarrior. If that doesn't work, erase the volume and re-install your data from your backups.

I have DiskWarrior running - it has been running for 15 hours actually, comparing directories now (about 300 GB of data, "7 million comparisons"). Is it possible that it takes so long? Or do you suspect an infinite loop? TIA Marc SignatureSwitzerland/Europe <http://www.heusser.com> remove CHEERS and from MERCIAL to get valid e-mail >> Try DiskWarrior.

Don't touch it - let it do its thing. Thanks for the help. I have the latest DW4.

It has been running now for a full week - 180 hours CPU, mostly "comparing directories". In activity monitor it does appear normal (not hung), and system CPU load on the 4 cores shifts from time to time, which looks pretty normal. Still - is it possible that it runs for so long, or is it in an infinite loop? When would you expect it to finish? Or what would you recommend to do? Restart the hard way? ...

Well, 300 GB is huge... I don't own DiskWarrior. So I can't tell you how long 300 GB should take. And I'm sure other factors can influence the speed (like fragmentation, etc.). If you are really concerned, give Alsoft a call and see what they think about it. SignatureJR > >>>> Try DiskWarrior.

I don't have a 300GB HD but I do have DiskWarrior. Another factor to consider is the amount of free space on the disk. The less that is available, the longer it takes DW to do its job. Try JR's suggestion and call or email Alsoft; I have found them to be very helpful. > >>>> Try DiskWarrior. If that doesn't work, erase the volume and re-install > >>>> your data from your backups.

The only time I encountered comparable DiskWarrior run times was when there were a large number of cross-linked files on the drive. It takes a long time to run down the extent lists and safely allocate new extents for the files. I shouldn't have to say it, but if cross-linked files are recovered, their contents must be verified. > If you are really concerned, give Alsoft a call and see what they think > about it. >> Try DiskWarrior.
