Subject: restarting raid arrays with uuid
Hi All
I'm not entirely sure this is rescuable. This is an old system that was kept on
for scratch storage space, unfortunately it was discovered some data hadn't
moved out of this area. The arrays disappeared after taking them offline and
rebooting the machine.
I've checked /etc/mdadm.conf
And mdadm --examine across all of the disks
I've assembled from uuid
Ran /proc/mdstat
Any suggestions as to what to try next?
After carefully looking at the arrays I have two back as they should be.
I've also discovered that one of the drives with gpt has a partition in it with ext4 data. Gparted has given me the device uuid which I can see in /dev/disk/by-uuid
Unfortunately it says no superblock information when I run mdadm --examine /dev/disk/by-uuid/<uuid number>
gparted does say ext4 is clean and it does have a --raid tag so my next question is is it safe to mount this drive, or is it best to dd it elsewhere to see what's on it?
Thanks
Bryan
