Dear Yan, OK, I will try to trigger the problem again and dump the information requested. Since it is not easy to get into this situation and I usually need to resolve it fast (its not a test system), is there anything else worth capturing? I will get back as soon as it happened again. In the meantime, I would be grateful if you could shed some light on the following questions: - Is there a way to cancel an individual operation in the queue? It is a bit harsh to have to fail an MDS for that. - What is the fragmentdir operation doing in a single MDS setup? I thought this was only relevant if multiple MDS daemons are active on a file system. ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 ________________________________________ From: Yan, Zheng <ukernel@xxxxxxxxx> Sent: 16 May 2019 05:50 To: Frank Schilder Cc: Stefan Kooman; ceph-users@xxxxxxxxxxxxxx Subject: Re: mimic: MDS standby-replay causing blocked ops (MDS bug?) > [...] > This time I captured the MDS ops list (log output does not really contain more info than this list).

Can you dump mds cache and send the output to us? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
