[Cache Disk Full Warning Docker and VMs Crash]

I think I solved it. I remembered that I have Veeam running on a Windows PC that backs up every night at 12:30. Looks like last night was a rather large job. The target for that backup is a share that utilizes the cache for speed, and then the mover moves it off the cache. But since it's an overnight backup, I will move the target to a new share that doesn't touch the cache at all.

 

Thanks for helping me discover my other issues though. I definitely need to sort out my zfs issues.

That was my thought. And you're right about other issues too. This morning the cache pool had returned to normal, but I couldn't get the docker service to start without initiating a full restart. Maybe I could have if I knew hot to do it from the command line. But back when this was a little more regular, the GUI would crash as well. The only thing that I can think that would do that much writing to the cache would be something like SABnzbd. But that hadn't had any activity since 11 last night. Could it be running a backup of my HomeAssistant VM? Those backups are only ~400MB though. No. They don't start running until 2:00am. I'm stumped for now. Is there a way to log the disk utilization by service?

That's what I see for disk utilization normally.

 

But overnight I'll get notifications that read: Unraid Cache disk disk utilization Alert [GEMINI] - Cache disk is low on space (100%) Description PCIe_SSD_21010751200007 (nvme1n1) Priority alert. I got that at 1:11am. That was the last one I got. The first one started at 12:41am at 71% and went up from there.

 

I will attempt to restore the sanoid.conf file and run a memtest to be sure. I'm trying to research what a sharecachefloor means, but not getting far.

Thanks for your help Jorge. Both the main pool and cache don't seem to be too full usually. Main Pool is around 47% and cache is 60%. Also I just noticed I don't have a scrub schedule for my cache pool. Oops.

This started happening almost a year ago, but hasn't happened for a long while now. I do get docker.img warnings above 70% when I do updates to my dockers, but that is temporary and goes back to normal after updates are complete.

 

But cache disks utilization at 100% is very confusing though as my cache disk is usually about 60%.

 

Diagnostics attached. Thank you for anyone who can help.

[[Support] Linuxserver.io - Nextcloud]

Hi all. I have a maybe unique question. How would I go about migrating my existing docker instance of Nextcloud (current image from linuxserver.io) to Unraid? It's currently set up on docker-compose in Proxmox. Search results return tones of tutorials in how to set up a new instance in Docker, and how to transfer from the oldschool install to docker. But nothing that I've found to transfer from 1 docker instance to a new docker instance (this time in Unraid.)

 

Any guidance would be appreciated.

[Commander Pro and Unraid]

Has there been any development on this? I tried passing mine through to an ubuntu VM but it's throwing errors that say essentially it doesn't want to read the temp sensors because it's a VM. Maybe I'm doing something wrong, not sure.
