October 11, 2025Oct 11 It started with no longer being able to connect to my Home Assistant VM. Then my Cache maxed out. Then Docker started misbehaving. Some apps would start. Some wouldn't (ex. AdGuard Home wouldn't start, but AdGuard Sync would). The final draw was when I could no longer Shut Down or Stop the Array from Main. I've attached my Diagnostic in hopes that I could get some help.All of my Drives appear to be Healthy.Thank you in advance! unraid-diagnostics-20251010-2203.zip
October 11, 2025Oct 11 Community Expert Solution The pool is completely full, note that having two different sized devices in raid1 will result in the smallest device capacity availble.Disable Docker and VM services, reboot, and see if you can free up some space on the pool, then re-enable the services and retest.
October 11, 2025Oct 11 Author Thank you very much for your reply!Looks like a completely full cache is the root of my problems. I have a few options.Stop Dockers and VMs and restart. Hope it clears up some space.Replaced the 250 GB drive in my cache with a 1 TB to mirror the existing one. This will give me an additional 750 GB.Question: can I change to a RAID 0 (Stripe) instead of RAID 1 (Mirror) in my cache?
October 11, 2025Oct 11 Author I realized I had a 1 TB in my gaming PC that I wasn't utilizing. Swapped the 250 GB for the 1 TB for my Cache pool and I'm up to 1 TB of Cache now (instead of 250 GB) and all is right with the world!Thanks again.
