[pve-devel] [PATCH pve-manager master v2 1/2] fix #6652: ceph: osd: enable autoactivation for OSD LVs on creation

[Max R. Carrara]

... by adding an inline helper sub for `lvcreate` instead of using the
LVM storage plugin's helper sub.

Autoactivation is required for LVs used by Ceph OSDs, as Ceph
otherwise doesn't activate them by itself.

This is a regression from f296ffc4e4d in pve-storage [0].
