Hi everyone,
I have a 3 nodes cluster running on PVE 6.4 with a total of 24 SSDs with CEPH.
Considering that:
- the cluster can be brought to a total stop
- each node is more than capable to host all the machines
- new SSDs are bigger (from 960GB to 1.92TB)
- I'd highly prefer to not stress the...
After adding a SSD into server, I rebuilded all OSDs to add cache for every OSD:
ceph-volume lvm prepare --data /dev/sdd --block.wal /dev/nvme0n1p4 --block.db /dev/nvme0n1p10
And now I wonder how to replace the ssd a few years later?
