Hi Michael, yes, you can use ceph-bluestore-tool to do that. E.g. bin/ceph-bluestore-tool --path dev/osd0 --devs-source dev/osd0/block.wal --dev-target dev/osd0/block.db --command bluefs-bdev-migrate inferring bluefs devices from bluestore path device removed:0 dev/osd0/block.wal Additionally you might probably need to zap wal device with ceph-volume after the migration to avoid its attachment to OSD on node restart. Not completely sure about that though... Thanks, Igor On 9/22/2020 10:09 PM, Michael Fladischer wrote:
Hi,
Is it possible to remove an existing WAL device from an OSD? I saw that ceph-bluestore-tool has a command bluefs-bdev-migrate, but it's not clear to me if this can only move a WAL device or if it can be used to remove it ...
