[SOLVED] Raid volume Unmounted

[MaartenKa]

Hello,

After a clean shutdown. Because we had to move the unit. The RAID volume wouldn`t come online?

So I did a check scan on all the disk. To be sure no disk had bad blocks or some like that. the SMART test also went okay.

After that I would like to mount te RAID set again. But all options are greyed out?

Did a check if the RAID set is still okay? It looks like it?

(sorry for my big post. But i would like to provide as much information as needed)

[~] # mount /dev/md0 /share/MD0_DATA/
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

dmesg:

Why does it say EXT3-fs? the unit always had EXT4?

here some extra info regarding the unit

Type: QNAP TS859U-RP+
RAID: 5
Firmware: 4.0.1 (latest)
OS using the QNAP: Windows 2008 R2 SP1
Function: Backup device B2D (replica)


Could some help me with this?? If more information is needed please let me know. I did al lot a reseach on but no luck for now?

[pwilson]

Could we perhaps start with some more basic information?

Please login to your NAS via "SSH" (login as "admin") and type the following commands:

Code: Select all

getcfg system version
df -h
cat /proc/mdstat
hdparm -i /dev/sd[a-h] 2>/dev/null | grep Model

Please cut&paste these commands to your NAS, and please cut&paste the output back to this message thread. Type "exit" to end your SSH session.

I find it curious that it only listed 4 of your 8 drives. Everything else looks normal, excepting that /dev/md0 isn't mounted as /share/MD0_DATA.
I would recommend contacting QNAP Customer Service for further assistance, or fill out the Online Support Form, please refer them to this message thread, as it already contains all the information they are likely to desire. Please refer them to: http://forum.qnap.com/viewtopic.php?f=25&t=79123

[MaartenKa]

Okay I will contact support.
about the disks it is strange.

thank you for your help. So far.

[MaartenKa]

I did so more research and I tried the following.

http://forum.qnap.com/viewtopic.php?p=224731

Only change the disks I had and let it run

Code: Select all

swapoff /dev/md8
mdadm -S /dev/md8

mkswap /dev/sdb2
mkswap /dev/sdc2
mkswap /dev/sdd2

swapon /dev/sdh2
e2fsck_64 -f /dev/md0
mount /dev/md0 /share/MD0_DATA/ -t ext4

the e2fsck_64 takes a long time. depeding on the amount of disks you have

This is perfect. Came back from vacation and booted up all the gadgets, and the NAS didn't come up. Told me to run a file check, but it was unavailable since the volume was unmounted. It also only listed the first 4 drives. Quite annoying, to say the least. Found this post, and now the NAS box is happy again (and so I am).

So, thanks for having my exact issue, and doing the "heavy lifting" for me (although I guess you would have preferred not to have to do the research in the first place )

I had the same problem with TS-809U after a firmware update, MaartenKa solution worked just fine, thanks!

[blfinche]

I had the same issue today after applying an update to 4.2.0 on a 639 PRO RAID 6 with 6 drives.

You will notice my swapoff command changed and I had less drives mkswap on. Also, my machine has e2fsck instead of e2fsck_64.


swapoff /dev/md6
mdadm -S /dev/md6
mkswap /dev/sda2
mkswap /dev/sdb2
mkswap /dev/sdc2
mkswap /dev/sdd2
mkswap /dev/sde2

swapon /dev/sdd2

e2fsck -f /dev/md0
mount /dev/md0 /share/MD0_DATA/ -t ext4
reboot

Good Luck
