Raid Data Volume issues "Check File System"

[jverdin]

Good Afternoon, Experienced a power outage and the Data / Volume /Lun is showing unmounted after reboot..

Web interface shows unmounted but the ssh session shows already mounted and I cannot perform a File System check. Any help would be appreciated.

For better readability please put such outputs in code tags (</>).
Try, if a

Code: Select all

ps -ef | grep -i md0

shows any process accessing the raid.
If so, kill this process, the PID is seen in the output.

Regards

Edit: a simple umount commands provides which output?

Sorry about that, thanks for replying.

Kill all the processes accessing MD0_Data.
Except the last, this is the ps -ef command.
Then try to run the filesystem check again.

If GUI cant run tbe filesystem check for any reason, try per CLI.
But I need to lookup the commands first, give me some minutes...

Regards

Edit: Try

Code: Select all

sudo e2fsck_64 -fp -C 0 /dev/md0

, if it will work afterwards.
But: You do all at your own risk! Dont blame me, if anything goes wrong! A backup is available?

[jverdin]

Yes, I have 3 back ups, but this is my new QNAP NAS and want it to come back up online.

Code: Select all

[~] # e2fsck_64 -fp -C 0 /dev/md0
/dev/md0 is mounted.
e2fsck: Cannot continue, aborting.

You must unmount it before you can perform the fsck:

Code: Select all

umount /dev/md0

[jverdin]

Thanks for your help.. I'm getting closer.
This process keeps on starting back up... any suggestions.
Still can't run check file system and it tells me to unmount the volume before running your command.

Code: Select all

[~] # umount /dev/md0
umount: /share/MD0_DATA: device is busy
umount: /share/MD0_DATA: device is busy

Code: Select all

[FSC830]

No, not really. I dont use this f*****ing multimedia stuff from QNAP.
Stopping/disabling multimedia library in GUI is not possible I guess?

Then best option is may be to create a support ticket.

How do I keep this process from running?

Code: Select all

17616 admin     14468 S   /usr/local/medialibrary/bin/[b]mytranscodesvr[/b] -u -debug -db /share/MD0_DATA

[jverdin]

Thanks FSC830, totally understand, I will uninstall all the multimedia apps and perform a NAS reset without losing data.

[jverdin]

I performed a reset of the NAS but now my /dev/md0 is missing. Any help would be appreciated. I can see the following..
