- Annoyance
Hello 
This seems to be a thing, problem many has noticed, but I could not find a bug report on it yet (maybe I did not look deep enough)
I first came across the problem on Reddit and then found out I had the same situation.
It looks to be related to docker, because if I/we shut down docker or does not run any dockers, nothing is written.
I cant say for sure if this happened with zfs before 6.12.3, but people on reddit seems to have noticed this on 6.12.3 and not before.
There is also the thing that zfs drives in array does not spin down if you have them on a timer, but this seems to be linked to ZFS-Master plugin IF you have the "Main" tab open as the plugin then reads the snapshot data and that wakes up the drive. But this does not explain the writes.
I have tried to isolate it to a specific docker, with no luck.
The writes also happens on zfs drives on the array, not only zfs-pools.
Anyone else know more about this?
