Hello ceph users and developers, I've stumbled upon a bit strange problem with Luminous. One of our servers running multiple QEMU clients crashed. When we tried restarting those on another cluster node, we got lots of fsck errors, disks seemed to return "physical" block errors. I figured this out to be stale RBD locks on volumes from the crashed machine. Wnen I removed the locks, everything started to work. (for some volumes, I was fixing those the another day after crash, so it was >10-15hours later) My question is, it this a bug or feature? I mean, after the client crashes, should locks somehow expire, or they need to be removed by hand? I don't remember having this issue with older ceph versions, but I suppose we didn't have exclusive locks feature enabled.. I'll be very grateful for any reply with best regards nik -- ------------------------------------- Ing.
