Re: [Linux-cluster] GFS file system corruption?



Sorry for posting this twice, I sent out the first version yesterday and figured it did not make it out when I did not see it this morning, so I posted a second version without any attachments this morning.  Next time I will be more patient.

>From the source code I compiled GFS 6.0.2.20-2.  The SAN is an ISCSI based storage system from LeftHand Networks.   Using ext3, the postmark disk test works fine, on a GFS file system, we get a number of errors.  The output from both postmark runs is below.

I unmounted the file systems, and ran gfs_fsck on the GFS system.  It produced a number of errors like these:
Pass4 complete
Starting pass5
ondisk and fsck bitmaps differ at block 17887
Succeeded.
ondisk and fsck bitmaps differ at block 17888
Succeeded.
ondisk and fsck bitmaps differ at block 17889
Succeeded.
ondisk and fsck bitmaps differ at block 17890
Succeeded.
ondisk and fsck bitmaps differ at block 17891
Succeeded.
ondisk and fsck bitmaps differ at block 17892
(The complete gfs_fsck output is attached, I compressed it because the file is quite large)
