Is ceph 20.2.2 coming to proxmox soon?

[psalkiewicz]

Hi,

Does anyone know if Tentacle 20.2.2 (already released on 16/06) will be available in proxmox no-subscription repo any soon?

I'm struggling with pg incostistencies in 20.2.1 and I wonder if 20.2.2 solved the issue.

Yes this is being worked on [1] and will likely be available from the Ceph test repository once released.

What are the inconsistencies?

I have a brand new AMD cluster running 20.2.1 and a separate cluster (three!) running upstream ceph providing RGW services.

I’m using erasure coding pool 3+2 on 5 node cluster and I turned on fast ec after upgrading to tentacle:

ceph osd pool set <pool_name> allow_ec_optimizations true

After that ceph started to come up with PG inconsistencies each few days. Since it’s a brand new feature I thought it would be good to check the newer ceph

this is the bug I was thinking of. If I recall correctly OSD need to basically be removed and redeployed if they were created before 20.2.1? I think.
