Bare-metal single disk Xpenology machine 6.2.3 randomly crashed (even after reboot)


Recommended Posts

hi everyone

@flyride

 

i hope some kind souls can help me.
I have a xpenology machine with a single ironwolf nas drive with btrfs filesystem. Yesterday it crashed, only thing i've done before has been restarting a docker container.
Saw some situation where the data could be accessed read-only, no luck here, even file station doesn't see any files.
I desperately need to copy a personal encrypted folder off of it and i don't have backups. I saw some threads but they leads to nothing cause I can't loose any data. My hope is to force remounting the volume since the hd seems fine or learn a way to copy files off from a live usb or windows pc.

I am running DSM 6.2.3-25426 Update 2

 

if someone knows how to retrieve the data i would really appreciate

I've already tried synologyCloudSyncDecryptionTool but on Windows it can't detect the drive, probably because Windows can't read BTRFS

 

 

Some screenshots that could help

all logs i could find were older than the date of the accident.

Not much posted here to be useful, plus you have no redundancy to work with.

 

You need to know the mount device for your filesystem.

 

# cat /etc/fstab

 

The line with /volume1 should tell you the mount device.  I expect it to be /dev/md2 but you need to verify this on your own system.

 

If it is /dev/vgXXX then you need to investigate the status of your LVM volume group:

https://xpenology.com/forum/topic/14337-volume-crash-after-4-months-of-stability/?do=findComment&comment=107934

 

If it is /dev/mdX then you can attempt some data recovery commands by following the thread starting here (ignore vgchange commands as they won't apply to you):

https://xpenology.com/forum/topic/14337-volume-crash-after-4-months-of-stability/?do=findComment&comment=107979

 

You should be prepared to add another drive or USB mounted device equal to or larger than your volume as a target for the recovered data.

some logs

what the best way to do a disk backup?

is there any other thing i could try in order to fix DSM?

Update and recap

 

 

Hi
I have a custom Synology Nas with DSM and xpenology

So far so good
Until 1 week ago when all the issues started
I've restarted a docker container 
No big deal until this
When the Nas restarted I've seen that the disk was unavailable and the "volume 1" has crashed
If you check on smart everything seems fine

I've tried basically anything I could fine online and didn't fix the issue

Now I bought a new external drive cause it's cheap and before trying anything else I want to back my "kinda working" Nas drive

How can I do that?
A cloning? 

Also another issue
A folder on this disk is encrypted and I have the key to decrypt with a program provided by Synology
