Are you **sure** this is the same system? Surely I'm missing something here... Can you provide details of the stripe, specifically "gstripe list" so I can see what the disks are and then ask you for "smartctl -a" output for each of them (to try and rule out disk-level problems that may be causing oddities at the layer underneathe the filesystem (sometimes fsck will not catch this))? -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Making life hard for others since 1977.
