Dear Ceph Community
We have 5 OSD servers running Ceph v15.2.17. The host operating system is Ubuntu 20.04.
One of the servers has suffered corruption to its boot operating system. Using a system rescue disk it is possible to mount the root filesystem but it is not possible to boot the operating system at the moment.
The OSDs are configured with (spinning disk) data drives, WALs and DBs on partitions of SSDs, but from my examination of the filesystem the configuration in /var/lib/ceph appears to be corrupted.
So my question is: what is the best option for repair going forward? Is it possible to do a clean install of the operating system and scan the existing drives in order to reconstruct the OSD configuration?
Thank you, Peter P.S. the cause of the original corruption is likely due to an unplanned
Hey Peter, A simple ceph-volume lvm activate should get all of the OSDs back up and running once you install the proper packages/restore the ceph config file/etc., If the node was also a mon/mgr you can simply re-add those services. Regards, Bailey power
outage, an event that hopefully will not recur. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
