Hello,
We have a cluster with 26 nodes, and 15 nodes have a bad batch of 2 nvme wheree we have for each 6 lv for db/wal. We have to change it, because they fail one by one...
The defective nvme are M2 samsung enterprise.
When they fail, we got sense errors, and the nvme disappear, if we power of the server, and power on, it come back... If we just do a soft reboot, the nvme don’t come back...
So we have decided to replace all of them by Intel pcie SSDPEDME016T4S
The original one are 1Tb, and the new are 1,6Tb
What is the best method to do that ?
put the node in maint mode, and do a pvmove of each and doing after a lv resize of each ?
Or there are a easier way to do that ? Like what I found in mailing list archives ?
ceph-bluestore-tool --path /var/lib/ceph/osd/ceph-${OSD}
bluefs-bdev-new-db --dev-target /dev/bluesfs_db/db-osd${OSD}
and
ceph-bluestore-tool --path dev/osd1/ --devs-source dev/osd1/block
--dev-target dev/osd1/block.db bluefs-bdev-migrate
For your understanding, we are in last Quincy and hardware is :
12 x 18tb sas
2 x nvme for db/wal
Thanks for advance for your insights
