I'm running a raid-5 setup at the house. Earlier today, an electrical storm caused a power outage and my system went down. When I got home, I booted the system and it complained bitterly about ReiserFS when trying to mount my raid array. It dropped me to root prompt and advised me to run fsck. I hit ctl-D and let the boot cycle complete. dmesg shows the following: sh-2006: reiserfs read_super_block: bread failed (dev 09:00, block 8, size 1024) sh-2006: reiserfs read_super_block: bread failed (dev 09:00, block 64, size 1024) sh-2021: reiserfs_read_super: can not find reiserfs on md(9,0) The above is repeated 3 more times. dmesg does see the four drives that should compose /dev/md0 (hde is a spare): # dmesg | grep hd ... hdc: Maxtor 6Y120P0, ATA DISK drive hdd: Maxtor 6Y120P0, ATA DISK drive hde: Maxtor 6Y120P0, ATA DISK drive hdg: Maxtor 6Y120P0, ATA DISK drive ... # cat /proc/mdstat: Personalities : [raid5] read_ahead not set unused devices: <none> # cat /etc/mdadm/mdadm.conf DEVICE /dev/hd* ARRAY /dev/md0 level=raid5 num-devices=3 UUID=fef44719:ddd66a49:0a337b48:b53e14c0 devices=/dev/hdg1,/dev/hdd1,/dev/hdc1 # mdadmin --assemble --scan mdadm: no devices found for /dev/md0 # cat /proc/partitions major minor #blocks name 34 0 120060864 hdg 34 1 120060832 hdg1 33 0 120060864 hde 33 1 120060832 hde1 22 0 120060864 hdc 22 1 120060832 hdc1 22 64 120060864 hdd 22 65 120060832 hdd1 3 0 39062500 hda 3 1 40131 hda1 3 2 996030 hda2 3 3 4883760 hda3 3 4 1 hda4 3 5 9767488 hda5 3 6 1461883 hda6 3 7 21912628 hda7 # mdadm -E /dev/hd[gedc]1 mdadm: No super block found on /dev/hdc1 (Expected magic a92b4efc, got 00000000) mdadm: No super block found on /dev/hdd1 (Expected magic a92b4efc, got 00000000) mdadm: No super block found on /dev/hde1 (Expected magic a92b4efc, got 00000000) mdadm: No super block found on /dev/hdg1 (Expected magic a92b4efc, got 00000000) How should I proceed in order to recover my array? If I've left out anything important, just let me know and I'll be glad to supply it. Thanks for any advice you guys have.
