Is ceph 20.2.2 coming to proxmox soon?

[Pawel Salkiewicz]

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.

Tentacle 20.2.2 is available in our Ceph test repo.

 

[Pawel Salkiewicz]

I upgraded ceph to 20.2.2 from test repo and after a couple of days got the same error:

2 scrub errors
no additional data
Possible data damage: 1 pg inconsistent
pg 12.61 is active+clean+inconsistent, acting [6,3,10,16,13]

Looks like it didn't solve the issue with fast EC. There are no issues with data or the vms but it keeps coming up with these errors.

Ceph 20.2.2 is now available in the ceph-tentacle enterprise repository.
