I believe that with the new lvm mandate, ceph-volume should not be complaining about
"missing PARTUUID".
This is stopping me from using my system.
Details on how to recreate:
1. have a system with 1 SSD and multiple HDDS
2. create a buncha OSDs with your preferred frontend, which will eventualy come down to
ceph-volume lvm batch --bluestore /dev/ssddevice /dev/sdA ... /dev/sdX
THIS will work great. batch mode will appropriately carve up the SSD device into multiple
LVMs, and allocate one of them to be a DB device for each of the HDDs.
3. try to repair/replace an HDD
As soon as you have an HDD fail... you will need to recreate the OSD.. and you are then
stuck. Because you cant use batch mode for it...
and you cant do it more granularly, with
ceph-volume --cluster ceph lvm create --bluestore --data /dev/sdg --block.db
/dev/ceph-xx-xx-xx/ceph-osd-db-this-is-the-old-lvm-for-ssd here
This isn't a bug. You're specifying the LV incorrectly. Just use
--block.db ceph-xx-xx-xx/ceph-osd-db-this-is-the-old-lvm-for-ssd
without the /dev at the front. The /dev path gets treated like a normal
block device.

none of the other block-db LVMs it created on the SSD in batch mode, have an partuuid
either!!
