I'm following your way to recover my lost partition. when i try mdadm.static -Af /dev/md6 /dev/sda11 mdadm.static -Af /dev/md6 /dev/sdb11 mdadm.static -Af /dev/md6 /dev/sdc11 then i reboot the machine /var partition can be activated but when i look to /var partition it was empty, there's no data at all. my data is lost ??? if it's true how to recover it ?? thanks a lot Regards Hendri > On Friday July 25, c4c3m@oke.net.id wrote: >> this is the messages from faulty machine: >> #mdadm.static -Eb /dev/sdc* >> >> ARRAY /dev/md4 level=raid5 num-devices=3 >> UUID=12a3daa6:98bc6aca:98d38bed: 414bad01 >> devices=/dev/sdc9 >> ARRAY /dev/md3 level=raid5 num-devices=3 >> UUID=5c4fb8f2:7aad3154:83515188: 5945a00b >> devices=/dev/sdc8 >> ARRAY /dev/md2 level=raid5 num-devices=3 >> UUID=31788297:ac6dab84:1dc952b3: fec35535 >> devices=/dev/sdc7 >> ARRAY /dev/md1 level=raid5 num-devices=3 >> UUID=ed01ad73:e4a5e4d0:90eb9b59: 15e5c3c0 >> devices=/dev/sdc6 >> ARRAY /dev/md8 level=raid5 num-devices=3 >> UUID=1708a6d1:96874201:39d9f451: bed35249 >> devices=/dev/sdc13 >> ARRAY /dev/md7 level=raid5 num-devices=3 >> UUID=f385575d:d3185f42:37e7d321: 4784a76c >> devices=/dev/sdc12 >> ARRAY /dev/md6 level=raid5 num-devices=3 >> UUID=cdcae134:499035b2:e539a33a: 636fa315 >> devices=/dev/sdc11 >> ARRAY /dev/md5 level=raid5 num-devices=3 >> UUID=59f4a4fc:40471289:9d6e0430: 44f950a1 >> devices=/dev/sdc10 >> ARRAY /dev/md9 level=raid5 num-devices=3 >> UUID=3b2e48f6:efb0795d:6fa8e6c7: 18e6d984 >> devices=/dev/sdc1,/dev/sdc3,/dev/sdc4 > > Thanks. > After you sent me separately the whole set of information (/dev/sd*, > not just /dev/sdc* ... why didn't you send it to the list too like I > keep asking?). > > It appears that your machine crashed and when it came back up, sdb and > sdc weren't accessable, so all the arrays got confused by the absense > of sdb and sdc. > You can fix it all up using the "-Af" or "--assemble --force" options > to mdadm. > so > > mdadm -Af /dev/md1 /dev/sd[abc]6 > mdadm -Af /dev/md3 /dev/sd[abc]8 > mdadm -Af /dev/md4 /dev/sd[abc]9 > mdadm -Af /dev/md5 /dev/sd[abc]10 > mdadm -Af /dev/md6 /dev/sd[abc]11 > > should make it mostly happy again. > This will make all of the raid5 array out of just two drives, the > 'best' two in each case. > Then you can add the third in. e.g. > mdadm /dev/md1 -a /dev/sdc6 > Note: this assumes it was sdc6 that was left out.
