Hello all I just ran into a problem with my RAID5 array. Everything seemed to run fine, but then suddenly froze and upon reboot the boot process wouldn't start from the array and panic'ed after a while. Here's the data I've been able to gather from my FC 5 linux rescue session: My partitions: /dev/hda2, /dev/hdc2, /dev/hde1, /dev/hdg1 /dev/hde is not working - lots of DriveReady SeekComplete Error and others # mdadm -V mdadm - v2.3.1 # mdadm -E /dev/hda2, /dev/hdc2 and /dev/hdg1 yields: Same on all: Magic: a92b4efc Version: 00.90.01 UUID : <long id> Raid Level: raid5 Raid Devices: 4 Total Devices: 4 Preferred Minor: 0 State: active Active Devices: 3 Working Devices: 3 Failed Devices: 2 Events: 0.4188000 Layout: left-symmetric Chunk size: 256K Number Major Minor RaidDevice State 0 3 2 0 active sync /dev/hda2 1 22 2 1 active sync /dev/hdc2 2 0 0 2 faulty removed 3 34 1 3 active sync /dev/hdg1 Different on all: Checksum # mdadm --assemble /dev/md0 /dev/hda2 /dev/hdc2 /dev/hdg1 mdadm: failed to RUN_ARRAY /dev/md0: Input/output error # cat /proc/mdstat md0: inactive hda2[0] hdg1[3] hdc2[1] # mdadm --detail /dev/md0 Persistence: Superblock is persistent State: active, degraded Active Devices: 3 Working Devices: 3 Failed Devices: 0 Number Major Minor RaidDevice State 0 3 2 0 active sync /dev/hda2 1 22 2 1 active sync /dev/hdc2 0 0 0 2311520 removed 3 34 1 3 active sync /dev/hdg1 I'm off to buy another 200GiB disk now, but is my current array doomed or do I have a chance? Any inputs would be highly welcome! thanks Johnny Ljunggren - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
