I have remove the partition:
# mdadm --remove /dev/md0 /dev/sda1 mdadm: hot removed /dev/sda1 from /dev/md0
# mdadm --remove /dev/md2 /dev/sda3 mdadm: hot removed /dev/sda3 from /dev/md2
Now i want to add the old partition (to sync the raid), unfortunately, comes an error message: # mdadm --add /dev/md0 /dev/sda1 mdadm: failed to write superblock to /dev/sda1
What is wrong here?
Looks like a hardware defect to me. That's probably also the reason why the RAID went degraded in the first place. Better replace that disk while the other one still holds the line.
HTH T.
yes, of course, the hardware is defective. I was confused because I've only works something like this more often, and otherwise a resync works. I was this morning certainly did not fit ;)
thanks
