OOH Thanks! I'll certainly give that a try. On Fri, Sep 8, 2023 at 7:50 PM Alexander E. Patrakov <patrakov@gmail.com> wrote:
Hello Dave,
I think your data is still intact. Nautilus, indeed, had issues when recovering erasure-coded pools. You can try temporarily setting min_size to 4. This bug has been fixed in Octopus or later releases. From the release notes at https://docs.ceph.com/en/latest/releases/octopus/:
Ceph will allow recovery below min_size for Erasure coded pools, wherever possible.

Hi Everyone, I've been fighting with a ceph cluster that we have recently physically relocated and lost 2 OSDs during the ensuing power down and relocation. After powering everything back on we have 3 incomplete 3 remapped+incomplete And indeed we have 2 OSDs that died along the way. The reason I'm contacting the list is that I'm surprised that these PGs are incomplete. We're running Erasure coding with K=4, M=2 which in my understanding we should be able to lose 2 OSDs without an issue. Am I mis-understanding this or does m=2 mean you can lose m-1 OSDs?
Also, these two OSDs happened to be in the same server (#3 of 8 total servers).
This is an older cluster running Nautilus 14.2.9.
Any thoughts? Thanks -Dave _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
