AW: QNAP 8 port RAID5 md0 recovery of missing MBR and md superblocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Greetings to all

As my thread from the 6.2.2014 didn't bring any hint or any reply or way out, I need advise if my way is approved:

I reconstructed the part table (testdisk import from a working disk) and now I'm only missing the md superblock on three disks (sdb3/sdf3/sdg3) for my md0 integrity.

I'd do the following:

a) "mdadm --stop /dev/md0"

b) "mdadm --create --assume-clean --verbose --force --run /dev/md0 --level=5 --raid-devices=8 /dev/sda3 missing /dev/sdc3 /dev/sdd3 /dev/sde3 /dev/sdf3 /dev/sdg3 /dev/sdh3"

or to include the "most datas available" version
c) "mdadm --create --verbose --assume-clean /dev/md0 --level=5 --raid-devices=8 /dev/sd{a,b,c,d,e,f,g,h}3"
to gather at least the older layout & data

d) "fsck.ext4 /dev/md0" on the array afterwards

Does anyone has something better in mind?

Cheers
Michael
