NSA310 - eSata disk status is DOWN

csipetcsapat

Hello,

I have a NSA310 with 2TB internal HDD and 4TB external HDD connected to esata.

After a power failure, the external disk status was changed to Down and it is not shared anymore (the internal HDD is working).

The S.M.A.R.T status shows no errors.I tried to fix it via the admin web UI, but "Scan Volume" returns a "Failed to scan volume." error.

I have tested it inPC with Linux (using commends from https://kb.zyxel.com/KB/searchArticle!gwsViewDetail.action?articleOid=013308&lang=EN ), I can mount it and the file system & files are not corrupted.

I connect to NAS with putty and the disk looks good:

root@nsa310:~# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1]
md1 : active linear sdb2[0]
      3906516992 blocks super 1.2 0k rounding

md0 : active linear sda2[0]
      1952997888 blocks 64k rounding

unused devices: <none>

e2fsck founds some incorrect nodes, but it fixes the errors, after that the disk is good:

root@nsa310:~# umount /mnt/extdisk/
root@nsa310:~# e2fsck.new /dev/md1
e2fsck 1.41.14 (22-Dec-2010)
/dev/md1: clean, 124570/244162560 files, 654272573/976629248 blocks

If I mount it manually, the disk is mounted correctly:

root@nsa310:~# mkdir /mnt/extdisk
root@nsa310:~# mount /dev/md1 /mnt/extdisk/
root@nsa310:~# ls -l /mnt/extdisk/

How can I switch back the 2nd HDD to Healthy state?

You can try the Telnet Backdoor and run dmesg on the NAS to find out why the disk isn't mounted.

The dmesg shows no error:

I think you left out a lot of lines. Here you can find the (serial) bootlog of a 325. The serial bootlog of a 310 shouldn't be much different. The lines from 'Linux version 2.6.31.8' until 'Freeing init memory: 3164K' should all be in dmesg, unless that much extra logging is added that the oldest lines are gone. (It's a 64 or 128kB memory buffer).

Between those lines I recognize these sata/disk related lines:

I expect on your box either some low level sata error, or a mounting problem, or no trace of a 2nd disk at all. But at least the 1st disk should show up, somehow.

Thank You for your support.

The previous output from the dmesg is full, no other lines are displayed ( I do not see any logs under the /var/log).

The 1st HDD is mounted correctly, and the 2nd HDD on esata can be monted manually (if I connect to telnet and mount it with command mount /dev/md1 /mnt/extdisk/ - it means the JBOD partitions are correct, just the NAS cannot mount it automatically from any reason).

Anyway, I will copying data to another external disk and format the disk again, it seems to be an internal issue with autodetecting of the disk during boot.
