Hi.

I'm quite new to this community and the unRAID in general. First let me congratulate both the team and the community for keeping and maintaining such a nice product. Got one Ugreen DXP6800 Pro, installed unRAID 7.2 and am playing in pre-production stage with it while waiting for the new drives to arrive. Got several dockers installed, they all were working OK. Till this morning when without any visible reason they all have just gone. My suspicions were at Appdata Cleanup plugin. Which I have just removed from the system, so it's not present at the diagnostics attached here. Strange enough the actual appdata entries were not cleared - just the dockers themselves have gone. The docker image is OK (I've changed its size to 35GB beforehand)

Since there was no actual data lost - just the dockers (I haven't installed any VMs before that) I'm going now to re-install all the dockers from previous apps section (very useful feature indeed) but still have this unpleasant feeling f uncertainty what has caused this behavior. I'm not far from the idea it was clearly my mistake somewhere down the road.

Any help/assistance would be highly appreciated

Kind Regards

Nick

Changing the size will recreate the docker.img file, causing you to have an empty image. So this is to be expected, and you have to reinstall via previous apps like you did.

Thanks for your really prompt reply. However, I changed the docker image file to 35GB prior to that issue. It was all OK till this morning. I'm very new and can't read well the diags for details. Read the syslog but found nothing suspicious. in there.

Ah, I see. It oculd maybe have been the cleanup appdta plugin if it deleted the docker.img. Haven't really used that plugin so I can't say how it's configured. But if you added the folder where the docker.img is in the settings and it somehow removed it, that could indeed be the cause. Can't really see anything suspicious in the logs.

Thanks again. The size of the docker image file was correct. I've run scrub on it and it showed the file/disk was empty (just ~400 bytes in it). I've removed this plugin and let's hope it'd be OK from now on.
