Hi,
Just a little question regarding this operation :
[root@osdhost osd]# ceph-volume lvm prepare --bluestore --data /dev/sdc
--block.wal /dev/sda2 --block.db /dev/sda1
On a previous post, I understood that if both wal and db are stored on
the same separate device, then we could use a single partition for
both...which means we could do :
# ceph-volume lvm prepare --bluestore --data /dev/sdc --block.wal
/dev/sda1 --block.db /dev/sda1
and so on with other uniq wal/db partition for other OSD...
Did I get that correctly ?
Thanks,
Hervé

I’m trying to create bluestore osds with separate --block.wal
--block.db devices on a write intensive SSD
I’ve split the SSD (/dev/sda) into two partditions sda1 and sda2 for
db and wal
I seems to me the osd uuid is getting changed and I’m only able to
start the last OSD
Do I need to create a new partition or logical volume on the SSD for
each OSD?
I’m sure this is a simple fail in my understanding of how it is
supposed to be provisioned.
Any advice would be appreciated.
Thanks,
Gary
