Re: [ceph-users] PGs stuck in active+clean+replay

Hi Greg, I’ve tested the patch below on top of the 0.94.5 hammer sources, and it works beautifully. No more active+clean+replay stuck PGs. Thanks! Andras On 10/27/15, 4:46 PM, "Andras Pataki" wrote: >Yes, this definitely sounds plausible (the

Re: [ceph-users] PGs stuck in active+clean+replay

Hi Greg, No, unfortunately I haven¹t found any resolution to it. We are using cephfs, the whole installation is on 0.94.4. What I did notice is that performance is extremely poor when backfilling is happening. I wonder if timeouts of some kind could cause PG¹s to get stuck in replay. I

Re: [ceph-users] PGs stuck in active+clean+replay

Yes, this definitely sounds plausible (the peering/activating process does take a long time). At the moment I’m trying to get our cluster back to a more working state. Once everything works, I could try building a patched set of ceph processes from source (currently I’m using the pre-built

Re: [ceph-users] pgs stuck in active+clean+replay state

I imagine you aren't actually using the data/metadata pool that these PGs are in, but it's a previously-reported bug we haven't identified: http://tracker.ceph.com/issues/8758 They should go away if you restart the OSDs that host them (or just remove those pools), but it's not going to hurt
