getting rid of high ssd write rates

[caplam]

Hello,

In 6.8.3 i have had hard time with excessive writes on ssd. I'm now with 6.9 beta30 and it seems i have the same problems. Like in 6.8.3 high writes are made trough loop2 device which is /var/lib/docker .

I like unraid but i'm not going to change my ssds every six months. So i'm considering dropping unraid docker engine.

I have 2 options :

- drop unraid but i don't want to. Now i'm more familiar with it, it would be a waste.

- drop the usage of docker engine.

 

for option 1 i guess freenas would be a viable option but besides the fact of learning a new os it has its downsides (choice of hard drives,...)

for option 2 i'm considering setting up an ubuntu vm with docker engine and portainer for managing containers, network, ....

 

How can i set up such a vm ?

which network adapter ?

which size of vdisk?

how to use existing appdata from containers ?

how to passtrough gpu to plex and tdarr dockers inside the vm ?

which data from the vm to backup and how ?

 

Is there someone who followed this path ?

Have you implemented any of the several options mentioned in the Release notes to cut down on excessive writes?    Simply updating without taking further action does not solve the issue so if you have not then you will still be getting excessive writes.

i thought setting up a cache pool with 1Mib aligned partition would be enough but that's not the case.

I saw your post in bug reports and right now i started docker service with the directory option (with a dedicated share).

For now i'm redownloading docker images but my dsl connections is so slow that i think it's a 24 to 48 hours process.

i have found a strange thing regarding ssd writes .it's related to vm. I'll post in bug reports
