Hi,
after an crash from an ohter harddisk (not member of this raid) i can't sync my Raid1 again. What have i done? Nothing, i removed this one death disk completly so the devicenames where changed. Before i removed the disk, my raid was SDA and SDC. After i removed the disk my raid was SDA and SDB.
So when ein will resync my raid it look like this:
| Code: | Personalities : [linear] [raid0] [raid1]
md1 : active raid1 sda1[0] sdb1[1]
513984 blocks [2/2] [UU]
md2 : active raid1 sdb2[2] sda2[0]
58099008 blocks [2/1] [U_]
[=>...................] recovery = 9.1% (5319936/58099008) finish=17.8min speed=49188K/sec
Personalities : [linear] [raid0] [raid1]
md1 : active raid1 sda1[0] sdb1[1]
513984 blocks [2/2] [UU]
md2 : active raid1 sdb2[2](S) sda2[0]
58099008 blocks [2/1] [U_]

When i take this command:
| Code: | mdadm --assemble /dev/md2 /dev/sda2 /dev/sdb2
mdadm: cannot open device /dev/sda2: Device or resource busy
mdadm: /dev/sda2 has no superblock - assembly aborted |
With force it is the same.
And i found this:
