Subject: [PATCH] lvm: do not run pvscan for lvmetad update
|
|
|
18971c |
|
|
|
18971c |
The lvmetad daemon is not yet running in initramfs so there's no
|
|
|
18971c |
need to run pvscan (or instantiate any lvm2-pvscan systemd service).
|
|
|
18971c |
If pvscan was called in this case (either directly or via systemd
|
|
|
18971c |
instantiated service), it would fail because there's no lvmetad
|
|
|
18971c |
daemon to update. This could cause confusion, especially in systemd
|
|
|
18971c |
instantiated service which is run only once!
