I want to recover files from a disk which has been part of a raid1
array. I don't want to mount it degraded, as all operations must be read
Can I mount the partiton of the disk as an ext4 filesystem (the raid was
formatted as ext4.)?
In my server to harddisks are used in mirrored array to save all
/dev/sdb1 and /dev/sdc1
today I created another md-device with the created partitions /dev/sdb2
and /dev/sdc2. Unfortunately I didn't edit the /etc/mdadm/mdadm.conf
When I rebooted the server I checked /proc/mdstat
and saw the following resync process:
md1 : active raid1 sdc sdb2
391382976 blocks [2/2] [UU]
[>....................] resync = 0.1% (745088/391382976)
That is wrong, as the first device is sdc, but it should be sdc2.
I halted the server and now have to recover the files from /dev/sdb1.
/dev/sdc1 could have suffered damage from the resync process.
I hope that you can help me with your advice.
