Been looking to replace an old 13-year old ubuntu server running about 40 docker-containers, plex being the most resource-hungry.
unRaid seemed like the perfect choice, as I'd love to have the possibility to spin up a VM to play some games now and then.
Getting the VM working went almost painlessly, passthrough on 1TB nvme-disk, 3060Ti, USB-PCIe-card, and 4 cores (8threads) of an i5-12600K.
Set up my array with 10TB parity Ironwolf, 3x8TB Barracuda for storage, 1.2TB Intel S3710 SSD as pool "cache".
A separate 1TB nvme as pool "services" for docker and whatever needed for other VMs down the road.
Spun up cloudflared, Portainer and Tailscale, everything working perfect.
VM stopped, containers running.
Started transfering movies off my old server, mouting it as a smb-share, using rclone sync.
Started getting btrfs corruption errors, did some googling, reformatted both pool drives to xfs, and tried again.
Having transfer speeds of about 35MB/s, both computers wired, but speeds would after some 15-20minutes start to slow down drasticly. I stopped the transfers, restarted, and same thing, slowing down.
Figured I'd move the stuff off the cache, so started the mover. Same thing here!
Speeds started at 50MB/s on parity + disk1, before slowing down to sub 1MB/s speeds.
Stopped the mover manually by doing mover stop, and noticed 2-3cores having high load, usually two at 100% while a thrid bumping up and down.
Rebooted the server, everything fine and idling at about nothing.
Restarted the mover, same thing! Stopped it again, 2-3cores keep on working, cache disk, parity and disk1 having blips of sub 1MB/s transfers, even though mover is stopped and nothing else is accessing them. About 10-15minutes later, everything suddenly went back to idling.
Did an attempt by skipping the cache, moving the files directly to the array (cache:no instead of cache: yes), initial speeds where higher, at about 45MB/s, but dropped alot faster, and most of my cores are at full usage.
Seems like something is not working as intended in my config, or I'm doing something wrong, but I have no idea left on where to look.
