Sorry that had to be Wido/Stefan Another question is: hoe to use this ceph-kvstore-tool tool to compact the rocksdb? (can't find a lot of examples)
The WAL and DB are on a separate NVMe. The directoy structure for an osd looks like: root@se-rc3-st8vfr2t2:/var/lib/ceph/osd# ls -l ceph-174 total 24 lrwxrwxrwx 1 ceph ceph 93 Aug 27 10:12 block -> /dev/ceph-97d39775-65ef-41a6-a9fe-94a108c0816d/osd-block-7f83916e-7250-4935-89af-d678a9bb9f29 lrwxrwxrwx 1 ceph ceph 27 Aug 27 10:12 block.db -> /dev/ceph-db-nvme0n1/db-sdd -rw------- 1 ceph ceph 37 Aug 27 10:12 ceph_fsid -rw------- 1 ceph ceph 37 Aug 27 10:12 fsid -rw------- 1 ceph ceph 57 Aug 27 10:12 keyring -rw------- 1 ceph ceph 6 Aug 27 10:12 ready -rw------- 1 ceph ceph 10 Aug 27 10:12 type -rw------- 1 ceph ceph 4 Aug 27 10:12 whoami Kind Regards Marcel Kuiper > Hi Wido/Joost > > pg_num is 64.
