fixing unmounted raid 1

[texastom]

newbie here using ts-253be with qvr pro to only store recordings from 4 cameras. I have 2 hdd in raid 1.
as of this AM. I can login to NAS but not qvr pro
getting msgs as follows

error msg- Pool 1 thin pool metadata could not be activated successfully
and
warning msg- default network shared folders public, web, etc are inaccessible

looking at system file info I see

datavol 1 status is unmounted

the only data on the system is all the stored cameras video for couple days, really don't need it.

can someone help me recover system the easiest way even if I lose the stored videos ?

thanks much

Thin volumes should not be used for CCTV, there are too many changes that need reclaiming.
More info needed, screenshots, what could have caused it?

For recovery do you see this?

Thanks for reply storageman
I did try that as listed in the post refered to but the "recover" is greyed out only option are check file and format
I am total newbie but did try ssh and md check disk does show the 2 drives as OK
storage screen shows as unmounted in qnap display

[storageman]

Yes try check file

[texastom]

check file bombs right off
error,, failed to check file system datavol1

maybe tomorrow I can get a human on the phone at qnap, unfortunately they can not log in to my system remotely as I use a hotspot for internet

What does SSH "md_checker" say?

Hi texastom,

Did you manage to solve this kind of issue? Can you share what's the tricks?

Thanks.

Md_checker looks ok

Launch this, it restarts LVM
"/etc/init.d/init_lvm.sh"

Never run /etc/init.d/init_lvm.sh command without the advice of a real expert who knows what he/she is doing.

For QNAP stuff, better contact QNAP support.

Never run /etc/init.d/init_lvm.sh command without the advice of a real expert who knows what he/she is doing.

... which is what happened here. @storageman is considered an expert on this forum.
