To be mor eprecise, what I want to know is:
I have a lot of bluestore osds and now I want to add separate wal and db on new nvme partitions. Would it be enough to just generate empty partitions with parted and make symlinks on the osd partition like this: $ sudo ln -sf /dev/disk/by-partlabel/osd-device-0-db /var/lib/ceph/osd/ceph-0/block.db $ sudo ln -sf /dev/disk/by-partlabel/osd-device-0-wal /var/lib/ceph/osd/ceph-0/block.wal Shall I use special partition ids or flags for db and wal ? And how big should I make db and wal partitions ?
