Unable to mount or recover Volume after power lost.

I've tried the steps before .... founded in this post :
viewtopic.php?p=224731

But when I try to execute e2fsck .... it says that DEV/MD1 is busy or locked by another programa,user, ....

Okay, I think you need to wait for QNAP's support to get in touch with you - reach out to them if you haven't already.

I've opened a ticked 11 hours ago. I hope they contact soon with me.

Thanks anyway

you might have to stop the services to do the e2fsck

depending on the firmware used you might also need the 64bit version of it

Code: Select all

# /etc/init.d/services.sh stop

Code: Select all

e2fsck_64 -f -v -C 0 /dev/md1

(that should also output the progress (and any errors encountered) to your current SSH session)

afterwards start the services again

Code: Select all

# /etc/init.d/services.sh start

The problem is that I really don't understand the first steps before e2fsck. I don't know what dev is correct to remplaze the md8 in this example:

swapoff /dev/md8
mdadm -S /dev/md8
mkswap /dev/sda2
mkswap /dev/sdb2
mkswap /dev/sdc2
mkswap /dev/sdd2
swapon /dev/sda2
swapon /dev/sdb2
swapon /dev/sdc2
swapon /dev/sdd2
e2fsck_64 -f /dev/md0
mount /dev/md0 /share/MD0_DATA/ -t ext4

In my particular case, I have only 3x6TB and dev/md1. I would be something like this:

swapoff /dev/mdX
mdadm -S /dev/mdX
mkswap /dev/sda1
mkswap /dev/sdb1
mkswap /dev/sdc1
#mkswap /dev/sdd2
swapon /dev/sda1
swapon /dev/sdb1
swapon /dev/sdc1
#swapon /dev/sdd2
e2fsck -f /dev/md1

I'm not sure if this are the correct steps.

Thanks again

[dolbyman]

not sure where all the other steps come from

after stopping the system services, examination is run (both commands posted above)

[jdgszorro]

I'm going to try it

[jdgszorro]

Error again, block resource. I'm restarting and try again.

[jdgszorro]

[~] # e2fsck -f -v -C 0 /dev/md1
e2fsck 1.41.4 (27-Jan-2009)
e2fsck: Device or resource busy while trying to open /dev/md1
Filesystem mounted or opened exclusively by another program?

After stop all the services running:

/etc/init.d/services.sh stop
/etc/init.d/opentftp.sh stop
/etc/init.d/Qthttpd.sh stop

How can obtain full access to md1 ??

[dolbyman]

did you stop the services before or after the check ?

best thing to wait for qnap .. so they can help with other steps (like unmounting the filesystem etc.) they will probably do a remote desktop session

[jdgszorro]

How long Qnap usually take to contact ?

[jacobite1]

How long Qnap usually take to contact ?

48 hours/2-3 working days.

By Tuesday at the latest now, but they're usually faster. I wouldn't be surprised if it's tomorrow.

I don't think it will hurt to update your ticket by linking to this thread and telling QNAP support in advance the steps you have taken.
