Hi, What exactly is the command to recover a raid array after system crash? I created a raid5 array with 3 disks. After system crash, one disk is out of sync, so I tried the command mdadm --assemble --run --force --update=resync /dev/md2 /dev/sbd3 /dev/sbd4 /dev/sbd5 However, I still saw that raid array was started with 2 disks: mdadm: /dev/md/2 has been started with 2 drives (out of 3). cat /proc/mdstat still shows that /dev/sbd5 is inactive. Personalities : [raid5] md2 : active raid5 sbd3[0] sbd4[1] 3968 blocks level 5, 64k chunk, algorithm 2 [3/2] [UU_] If --update=resync isn't the right option to sync a raid array, what command am I supposed to use?
