Is there any specific reason to try that manually this way? Why not
let cephadm handle that for you? There are scenarios where I need to
create VGs/LVs manually as well, but I do it from the host, not within
cephadm, and then let cephadm manage the devices.
Zitat von Ed Krotee <ed.krotee@xxxxxxx>:
Trying to create the Block and Block.DB devices for BlueStore.
Within the cephadm shell able to run the vgcreate but get the
following errors and we cannot see the vg device in /dev so doesn't
seem to actually create the vg, but vgs within the cephadm shell
shows it, but vgs at the o/s level does not. FYI - SE Linux is
disabled.
stdout: Physical volume "/dev/sda" successfully created.
Not creating system devices file due to existing VGs.
