Re: XFS on RBD on EC painfully slow

by Sebastian Knust

Hi Reed, To add to this command by Weiwen: On 28.05.21 13:03, 胡玮文 wrote: > Have you tried just start multiple rsync process simultaneously to transfer different directories? Distributed system like ceph often benefits from more parallelism. When I migrated from XFS on iSCSI (legacy system, no Ceph) to CephFS a few months ago, I used msrsync [1] and was quite happy with the speed. For your use case, I would start with -p 12 but might experiment with up to -p 24 (as you only have 6C/12T in your CPU). With many small files, you also might want to increase -s from the default 1000. Note that msrsync does not work with the --delete rsync flag. As I was syncing a live system, I ended up with this workflow: - Initial sync with msrsync (something like ./msrsync -p 12 --progress --stats --rsync "-aS --numeric-ids" ...) - Second sync with msrsync (to sync changes during the first sync) - Take old storage off-line for users / read-only - Final rsync with --delete (i.e. rsync -aS --numeric-ids --delete ...) - Mount cephfs at location of old storage, adjust /etc/exports with fsid entries where necessary, turn system back on-line / read-write Cheers Sebastian [1] https://github.com/jbd/msrsync

Graphics in ceph dashboard

by Fyodor Ustinov

Hi! I installed fresh cluster 16.2.4 as described in https://docs.ceph.com/en/latest/cephadm/#cephadm Everything works except for one thing: there are only graphics in the hosts / overall performance, (only the CPU and the network). In all other places the inscription "no data". What could I have done wrong? WBR, Fyodor.

cephadm shell fails to start due to missing config files?

Hello I am getting an error on one node in my cluster (other nodes are fine) when trying to run "cephadm shell". Historically this machine has been used as the primary Ceph management host, so it would be nice if this could be fixed. ceph-1 ~ # cephadm -v shell container_init=False Inferring fsid 79656e6e-21e2-4092-ac04-d536f25a435d Inferring config /var/lib/ceph/79656e6e-21e2-4092-ac04-d536f25a435d/mon.ceph-1/config Running command: /usr/bin/podman images --filter label=ceph=True --filter dangling=false --format {{.Repository}}(a){{.Digest}} /usr/bin/podman: stdout docker.io/ceph/daemon-base@sha256:0810dc7db854150bc48cf8fc079875e28b3138d070990a630b8fb7cec7cd2ced /usr/bin/podman: stdout docker.io/ceph/ceph@sha256:54e95ae1e11404157d7b329d0bef866ebbb214b195a009e87aae4eba9d282949 /usr/bin/podman: stdout docker.io/ceph/ceph@sha256:16d37584df43bd6545d16e5aeba527de7d6ac3da3ca7b882384839d2d86acc7d Using recent ceph image docker.io/ceph/daemon-base@sha256:0810dc7db854150bc48cf8fc079875e28b3138d070990a630b8fb7cec7cd2ced Running command: /usr/bin/podman run --rm --ipc=host --net=host --entrypoint stat -e CONTAINER_IMAGE=docker.io/ceph/daemon-base@sha256:0810dc7db854150bc48cf8fc079875e28b3138d070990a630b8fb7cec7cd2ced -e NODE_NAME=ceph-1 docker.io/ceph/daemon-base@sha256:0810dc7db854150bc48cf8fc079875e28b3138d070990a630b8fb7cec7cd2ced -c %u %g /var/lib/ceph stat: stdout 167 167 Running command (timeout=None): /usr/bin/podman run --rm --ipc=host --net=host --privileged --group-add=disk -it -e LANG=C -e PS1=[ceph: \u@\h \W]\$ -e CONTAINER_IMAGE=docker.io/ceph/daemon-base@sha256:0810dc7db854150bc48cf8fc079875e28b3138d070990a630b8fb7cec7cd2ced -e NODE_NAME=ceph-1 -v /var/run/ceph/79656e6e-21e2-4092-ac04-d536f25a435d:/var/run/ceph:z -v /var/log/ceph/79656e6e-21e2-4092-ac04-d536f25a435d:/var/log/ceph:z -v /var/lib/ceph/79656e6e-21e2-4092-ac04-d536f25a435d/crash:/var/lib/ceph/crash:z -v /dev:/dev -v /run/udev:/run/udev -v /sys:/sys -v /run/lvm:/run/lvm -v /run/lock/lvm:/run/lock/lvm -v /var/lib/ceph/79656e6e-21e2-4092-ac04-d536f25a435d/mon.ceph-1/config:/etc/ceph/ceph.conf:z -v /etc/ceph/ceph.client.admin.keyring:/etc/ceph/ceph.keyring:z -v /var/lib/ceph/79656e6e-21e2-4092-ac04-d536f25a435d/home:/root --entrypoint bash docker.io/ceph/daemon-base@sha256:0810dc7db854150bc48cf8fc079875e28b3138d070990a630b8fb7cec7cd2ced Error: error checking path "/var/lib/ceph/79656e6e-21e2-4092-ac04-d536f25a435d/mon.ceph-1/config": stat /var/lib/ceph/79656e6e-21e2-4092-ac04-d536f25a435d/mon.ceph-1/config: no such file or directory The machine in question doesn't run a mon daemon (but it did a long time ago), so I am not sure why "cephadm shell" on this particular machine is looking for mon.ceph-1/config Can anybody help?

Remove objectstore from a RBD RGW cluster

by Szabo, Istvan (Agoda)

Hi, I want to remove all the objectstore related things from my cluster and keep only for RBD. I've uninstalled the RGW services. Removed the haproxy config related to that. When I try to delete realm, zone, zonegroup it is finished but after coupe of minutes something recreate another zonegroup. I can't figure out what. What I miss? PS: The pools are still there, that will be the last step, hope I don't miss any necessary step.

how to compare setting differences between two rbd images

by Philip Brown

I have two rbd images. running fio on them, one performs very well, and one performs poorly. I'd like to get more insight on why. I know that rbd info xx/yyy gives me a small amount of information. but I cant seem to find a detailed info dump, in the way you can do things like ceph daemon osd.9 config show I cant even get useful google hits on things like "ceph find rbd image stripe-unit" all the pages seem to detail how to set the value, but not how to query it. Can anyone point me in the right direction? -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com

Hi, mapping of rbd volumes fails clusterwide. The volumes that are mapped, are ok, but new volumes wont map.

For now, i am out of idea's, can someone lead a way to analyse / fix this ? New volumes can be created and removed without issues. But they wont map.
