RAID 10 repair

Post by dmanghani » 2019/07/05 11:54:15

Help,
Somehow I screwed up on my RAID10 and need help to recover.
when I boot into emergency mode /dev/md126 & /dev/127 are missing, mdadm gives no help show blank.
when I boot into rescue mode mdadm shows both /dev/md126 & md127 however I am unable to recover or restore, mdadm shows devices as clean.
please help

Have you created an "/etc/mdadm.conf" ?

First go to rescue and check that you can mount your filesystems - this will prove your mds are OK.
Then run

Code: Select all

cat /proc/cmdline
mdadm -Q /dev/md126
mdadm -Q /dev/md127
