Unable to mount or recover Volume after power lost.

[jdgszorro]

Hi all,
this morning after a power lost, my TS453A with firmware 4.2.4, start to fail. The main volume, Volume 1, was unmounted and when I try
to check it, I get an error "pool 1 Error examinning VOL 1" at 1% (after 10´15 secs).

I've openned a ticked but I really need to recover and mount de raid volume as soon as possible.

Can someone help me ?

Thanks.

SSH in and check

cat /proc/mdstat

and get in the process of getting a UPS asap (and doing backups!)

Could yo give me the steps to solve it ?. More detailed please.

If I lose the volume my wife will kill me for sure.

Thanks.

Okay I'll walk you through the first bit.

If you use Windows, you'll need to download Putty http://www.putty.org/

Once you've got Putty open let me know, my windows10 machine is being super slow.

Okay then type in/copy

Code: Select all

cat /proc/mdstat

into the ssh command line and hit enter - this will tell you the status of your array and give you an output, please post it here in the code wrapper like this:

That's mine, and it's a healthy array.

I've 3x6TB WD RED in RAID 5 (Volume 1 -- Problem) and 10TB Seagate in a Raid 1 (Volume 2--- Working).

[jacobite1]

Okay I'm a little confused so I'm going to do some reading up for you now - you've got [3/3] [UUU] which means 3 healthy drives in your r5 array. Hopefully someone more capable than me like dolbyman can help whilst I'm reading about MDADM (qnap raid)

SSH in and check

cat /proc/mdstat

(dolbyman I've quoted you just to make sure you see OP's cat /proc/mdstat output, sorry!)

EDIT: Op in the meantime please run the following Hard drive smart test by copying the following code:

Code: Select all

getsysinfo hdsmart 1

and change 1 to 2 and 3 like this

Code: Select all

[~] # getsysinfo hdsmart 1
GOOD[~] # 
[~] # getsysinfo hdsmart 2
GOOD[~] # 
[~] # getsysinfo hdsmart 3
GOOD[~] # 
[~] # getsysinfo hdsmart 4
GOOD[~] # 

[jdgszorro]

OK. Thanks

The problem is that md1 is unmounted and when I try to check the system file integrity from web storage manager. I get an error. Pool 1 error checking and can't mount.

Done.... waitting to finish.

[jacobite1]

Done.... waitting to finish.

Waitwaitwait don't copy the second box of code, just the first. Increment the number each time it performs and output.

Also I don't know why it won't mount. You can manually unmount and mount a RAID array using SSH but you really don't have to have to do that.

But may be the solution is to use "e2fsck" to force the validation ?
e2fsck -f /dev/md1

I've seem it in a previous post. But ..... I'm not sure and I don't want to lose the data.
