Disk /dev/md0 doesn't contain a valid partition table
Posted: Sat Mar 24, 2012 9:32 pm
Hello everyone. I just experienced my first problem with a QNAP device in about two years, and if anyone has any suggestion on how to remedy this I would appreciate it.
(TS559 Pro currently on 3.6.0 B0210T. Upgraded firmware approximately one month ago, and have not rebooted since then).
After sitting idle for a couple of hours, I tried to access QNAP drive shares in windows and was unsuccessful (but was able to connect to web console). I could not see any disks under Volume Management or HDD S.M.A.R.T. I initiated a restart, but after almost half an hour the display on the QNAP still said restarting (and I was still able to access the web console). I tried to initiate a shutdown, but this did nothing either. I then turned off the QNAP using the power button, and after 30 seconds turned it back on.
The QNAP came back online, but I was still unable to access shares or see any disks in Volume Management or HDD S.M.A.R.T. I fired up an SSH connection with Putty, and ran the following:
fdisk -lu
mdadm -D /dev/md0
cat /proc/mdstat
cat /etc/config/mdadm.conf
cat /etc/raidtab
df -h
dmesg
There are no errors in the system log (just warnings related to resyncing due to my ungraceful shutdown.
Any ideas on how to fix this?
Thanks!
