Can't mount a RAID1 disk (version 0.90.03)
by TTWE from LinuxQuestions.org on (#4WNGE)
Hello, I have been trying to mount 1 disk out of a RAID 1 array,
I have tried following this guide
(https://blog.sleeplessbeastie.eu/201...r-using-mdadm/)
However when I have run the command sudo mdadm --examine /dev/sdb3 /dev/sdb3
I get the output:
Magic : a92b4efc

UUID : ca25cdc9:4ca5e97e:ba66bcea:637957b5

Number Major Minor RaidDevice State
this 1 33 3 1 active sync
0 0 22 3 0 active sync
1 1 33 3 1 active sync
I then try to run $ sudo mdadm -A -R /dev/sdb3
but I get the error:
mdadm: device /dev/sdb3 exists but is not an md array.
When I try to mount the drive /dev/sdb I get the error:mount: /dev/sdb: can't find in /etc/fstab.
I have tried looking at the drive and it tells me that it is a "Linux File system" (I don't know if this helps?) but i really want to mount the drive to get the data off it. Any help about where I may be going wrong would be a great help.
Many Thanks TTWE!
