QNAP controlled filesystem degraded

[ascl00]

I have a QNAP 670 which has been restarting approximately once every 7-10 days for reasons I am yet to track down. However, I have noticed that some of the volumes are running in a degraded state:

 # mdadm --detail /dev/md* | egrep -e '(State :|Array Size|md)'

unused devices: <none>

Note that my data volume (md1) is fine (thankfully), and the remainder are not volumes I have actively created.

Code: Select all

# df -h | grep '/dev/md'
/dev/md9                493.5M    151.3M    342.2M  31% /mnt/HDA_ROOT
/dev/md13               417.0M    375.9M     41.1M  90% /mnt/ext

But this means they do not appear in the UI at all, I only see md1 in the UI. So.... what should I do?

EDIT: None of the disks appear to have errors reported in the UI, and, in fact, I cannot see any issues at all via the UI.


EDIT2: I am beginning to think this is just the way those volumes are configured... as it would mean (I think) that any disks added will automatically get a mirror'd copy of the OS. Meaning this is normal maybe?
