Mbits/sec does not equal MB/s... 1MB is 8Mbs (8 bits to a byte) Therefore your rsync transfer speed was 24.32 Mbits/s (pretty much spot on your iperf3 test) Mbits/s is often also written as Mb/s. The uppercase vs lowercase B is an important differentiation .

I just experienced this issue with several containers (Nextcloud, Swag, Sonarr, Radarr, Plex, and a few more) and was able to fix it so I thought I would share what I did in case anyone came looking in the future. I was having issues with steps 4-7 causing my server to hang and the GUI to become unresponsive so here's what I tried that ultimately worked for me: Try steps 4-7. If they don't work or cause a server hang, comeback and start at 2. Shutdown Unraid (force it if you have to and are comfortable with the risk) Once restarted, stop any running containers (not sure if necessary but I did it as a precaution) Delete orphaned images via the bottom of the Docker tab in Advanced mode. While still in Advanced mode, force update any containers that were failing to start with the error listed by OP. Disable and re-enable the docker service via Settings > Docker (not sure if required, did this as a shortcut to get containers to auto-start rather than manually starting each). Check your docker tab and attempt to start anything that hasn't auto-started, they should all start as expected.

Can you share how you managed to reformat the pool if you were unable to stop the array? I'm having the same issue right now and it's looking like a reformat is my only option.
