All Data Gone, Why?

Featured Replies

Hey everyone,

 

todayI had a memory leak I guess, 75% of 64GB RAM used.
I got many errors navigating the UI (especially on the docker and apps tabs).

After a restart, all my docker containers have lost their data and can't start anymore.

Seems like the data in disk1/appdata has been affected, just all configured data is gone, the rest is fine.

Vaultwarden works fine, for Plex I had to regenerate all thumbnails, everything else seems to be working fine.

Gitlab does not start anymore and it looks like all data has been lost


Any tips?

diagnostics? (hopefully syslog "save to usb" was turned on before)

Don't think I enabled that, is it under the syslog server settings?
*Local Syslog Server is disabled

"Mirror to flash" was turned off. What now?

turn it on and wait for the next crash to happen.

Without it, all messages are gone after the reboot you did.

The "crash" happened after multiple years of no problems... :/

Filesystem      Size  Used Avail Use% Mounted on
/dev/md1p1      1.9T  1.2T  717G  63% /mnt/disk1

 

There's only one disk, and it's mounting and has data, so it's not a filesystem issue, if there is data missing, it may have been deleted/moved by someone/something.

Like I said, it looks like all changes in all of my containers (some running over 2 years) I did have been reverted after the high RAM problem and a subsequent restart.

Why do you have 200G docker.img? Have you had problems filling it? That is many times larger than should be necessary if things are configured correctly.

No idea, where would I configure the size? Maybe just precaution years ago?

According to those diagnostics, it was only using 15G of the 200G. If usage isn't growing, we can take a look at that later.

 

How many containers do you have?

18, of which only 6 were running all the time.

Is this someting useful?

Do any of them have a host path that isn't to a user share?

I am not completely understanding that question (noob), but is this what you are inquiring about?

Both homarr settings, as well as gitlab data are gone

Vaultwarden is still completely fine: /data/mnt/user/appdata/vaultwarden

Data in /mnt/disk1/JDownloaderDownloads is fine, Data in /mnt/disk1/appdata/jdownloader2/ has been reset

So it looks like only docker data in  /mnt/disk1/appdata/ has been reset to the default values?
Unfortunately, for homarr that would not explain the problem...

Looks like you have the appdata backup plugin installed. So do you have backups of your appdata?

YES!!!! In there I got vaultwarden (didn't break) but also homarr and plex (which broke).

Gitlab was not configured to backup external Data ....
downloader was actually set to be skipped during backup ....

Just gotta look into restoring the backup and reconfigure the missing backups correctly.
No real data loss in gitlab, since I also have everything locally, but still sucks.

THANK YOU VERY MUCH FOR YOUR SUPPORT, Ricky!

So, I tried to delete unused docker images and I am getting execution errors and the UI is Almost unusable now, CPU at 100%

To me it feels like the SSD is dying right now

Just noticed you have nvme as disk1. SSDs in the array cannot be trimmed, and can only be written at parity speed (you don't have parity).

 

The best place for SSDs is in pools outside the array. But, since you are on an old version of Unraid, you are required to have an array.

 

Not clear there is anything wrong with disk1 though.

 

You might try deleting and recreating docker.img (at only 30G this time)

 

https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file

 

then reinstalling your containers from Previous Apps.

Yeah, I had to use the SSD in the array...

Might as well try to update to the most recent version, if I then can move the nvme from array to pool and keep using it. 
Is there a manual way to call trim on the ssd?

I think you would have to remove it from the array first
