[6.12] High I/O load when system is idle, random freeze

Changed Status to Open

Changed Priority to Urgent

I tried to stop dockers none would stop

I tried to stop the array but it hangs on "Sync filesystems..."
I tried to shutdown the server but it doesn't do anything

I don't want to loose data, so I don't know what to do.

After 6h the server shut down. I started it again but now it hangs on "Mounting disks..." when starting the array.

Only processes that seem to do anything while the array is still starting are z_fr_iss_X and z_rd_int_X where X is either 0 or 1

Array is now started and doing a parity check.  Docker didn't start with "Couldn't create socket: [2] No such file or directory" and nothing else is running.  I will try to restart again after the check is complete.

I noticed almost all of my user shares are gone that were on a zfs pool.  I started a scrub and wait for the result.

Meanwhile the log is spammed with messages like

Jun 20 01:24:19 Tower emhttpd: error: malloc_share_locations, 7201: Operation not supported (95): getxattr: /mnt/user/appdata

(that share is on the array)
