Hi, I wondering why the md raid5 does accept writes after 2 disks failed. I've an array built from 7 drives, filesystem is XFS. Yesterday, an IDE cable failed (my friend kicked it off from the box on the floor:) and 2 disks have been kicked but my download (yafc) not stopped, it tried and could write the file system for whole night! Now I changed the cable, tried to reassembly the array (mdadm -f --run), event counter increased from 4908158 up to 4929612 on the failed disks, but I cannot mount the file system and the 'xfs_repair -n' shows lot of errors there. This is expainable by the partially successed writes. Ext3 and JFS has "error=" mount option to switch filesystem read-only on any error, but XFS hasn't: why? It's a good question too, but I think the md layer could save dumb filesystems like XFS if denies writes after 2 disks are failed, and I cannot see a good reason why it's not behave this way.
Do you have better idea how can I avoid such filesystem corruptions in the future? No, I don't want to use ext3 on this box. :) my mount error: XFS: Log inconsistent (didn't find previous header) XFS: failed to find log head XFS: log mount/recovery failed: error 5 XFS: log mount failed -- d - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
