Re: [ceph-users] 14.2.2 - OSD Crash

Hi Manuel, as Brad pointed out timeouts and suicides are rather consequences of some other issues with OSDs. I recall at least two recent relevant tickets: https://tracker.ceph.com/issues/36482 https://tracker.ceph.com/issues/40741 (see last comments) Both had massive and slow reads from RocksDB which caused timeouts.. Visible symptom for both cases was unexpectedly high read I/O from underlying disks (main and/or DB). You can use iotop for inspection.., These were worsened by having significant part of DB at spinners due to spillovers. So wondering what's your layout in this respect: what drives back troublesome OSDs, is there any spillover to slow device, how massive it is? Also could you please inspect your OSD logs for the presence of lines containing "slow operation observed" substring. And share them if any.. Hope this helps.

Re: [ceph-users] OSD's keep crasching after clusterreboot

Hi, as a follow-up: * a full log of one OSD failing to start https://pastebin.com/T8UQ2rZ6 * our ec-pool cration in the fist place https://pastebin.com/20cC06Jn * ceph osd dump and ceph osd erasure-code-profile get cephfs https://pastebin.com/TRLPaWcH as we try to dig more into it, it looks like a bug in the cephfs or erasure-coding part of ceph.

The plan is to use the ceph bluejeans video conferencing and it will be put on the ceph community calendar. I will send out links when it is closer to the 24th. The goal of this user group is to promote conversations and sharing ideas for how ceph is used in the the scientific/hpc/htc communities. Please be willing to discuss your use cases, cluster configs, problems you've had, shortcomings in ceph, etc... Not everyone pays attention to the ceph lists so feel free to share the meeting information with others you know that may be interested in joining in. Contact me if you have questions, comments, suggestions, or want to volunteer a topic for meetings. I will be brainstorming some conversation starters but it would also be interesting to have people give a deep dive into their use of ceph and what they have built around it to support the science being done at their facility.

At cephalocon we mostly had teams present from the EU so I'm interested in hearing how much community interest there is in a ceph+science/HPC/HTC user group meeting.

Can kstore be used as OSD objectstore backend when deploying a Ceph Storage Cluster? If can, how to?
by R.R.Yuan 07 Aug '19

07 Aug '19

Hi, All, When deploying a development cluster, there are three types of OSD objectstore backend: filestore, bluestore and kstore. But there is no "--kstore" option when using "ceph-deploy osd"command to deploy a real ceph cluster. Can kstore be used as OSD objectstore backend when deploy a real ceph cluster? If can, how to ? Thanks a lot R.R.Yuan

I'm looking at decommissioning a pool (rbd) that is the header and metadata storage pool for a number of ec backed images (created with --data-pool ecrbd). Pool ecrbd is remaining intact so I don't want to have to migrate all the image data if unnecessary. Is there a way to migrate all the header and metadata off of pool rbd to pool rbdnew, while leaving all the data inplace?
