Hi, if the OSDs are deployed as LVs (by ceph-volume) you could try to do a pvmove to a healthy disk. There was a thread here a couple of weeks ago explaining the steps. I don’t have it at hand right now, but it should be easy to find. Of course, there’s no guarantee that this will be successful. I also can’t tell if Igor‘s approach is more promising. Zitat von Igor Fedotov <igor.fedotov@croit.io>:
Hi Carl,
you might want to use ceph-objectstore-tool to export PGs from faulty OSDs and import them back to healthy ones.
The process could be quite tricky though.
There is also pending PR (https://github.com/ceph/ceph/pull/54991) to make the tool more tolerant to disk errors.
The patch worth trying in some cases, not a silver bullet though.
And generally whether the recovery doable greatly depends on the actual error(s).
Thanks,
Igor

Hi, I have a small cluster with some faulty disks within it and I want to clone the data from the faulty disks onto new ones.
The cluster is currently down and I am unable to do things like ceph-bluestore-fsck but ceph-bluestore-tool bluefs-export does appear to be working.
Any help would be appreciated
Many thanks Carl _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
