April 19, 20242 yr Hi unraid community, I got the problem "unable to write to cache" (via fix common problems plugin) after a some days in Unraid. Then my Home Assistant VM freezes and the Dockers are stopped. I then have to reboot unraid and everything is working again but only for some days and than "randomly" the problem reappears. When I got the problem my Home Assistant VM which has a capacity of 32GB gets all the 32GB allocated. When everything is fine only 11GB gets allocated. I have one 2TB nvme from Teracle as a cache (xfs) and 2x 12TB HDD (btrfs) where one is set up as a parity disk. I have attached the diagnostics. Do you have a clue what the problem could be? tux-diagnostics-20240419-2112.zip

I got no freeze in these days. Thank you.
