[[6.8.3] docker image huge amount of unnecessary writes on cache]

and today i moved from mirror BTRFS Cache to Single SSD Cache XFS on my main Unraid Server... Took ages..

And write are much lower now... 100kb/sec to 900kb/sec  and not 30+mb/sec like before...

When do Devs solve this issue with BTRFS Cache abnormal Writes?
i would love to get my mirrored Cache SSD back...

[[6.8.3] docker image huge amount of unnecessary writes on cache]

i just done this to my Test unraid server aswell. 
recreated my cache into XFS, from BTRFS. used mover to move shares from my cache to array while vm and docker services are disabled. then setting use cache to Yes and activate mover.

i see no performance difference as of now...

i hope Unraid devs look at this issue...

[[6.8.3] docker image huge amount of unnecessary writes on cache]

i have looked at all dockers and no logfile locations are on cache, but in /tmp/

No VM online

about 15 minutes iotop 😞

 

[[6.8.3] docker image huge amount of unnecessary writes on cache]

i see the same thing here, 

monitoring with Zabbix i see avg 300writes/sec to my 2 Cache drives.
