Description Sven Wegener gentoo-dev 2024-12-30 15:37:55 UTC
VGs and LVs have an internal autoactivation flag that specifies whether they should be automatically activated during system initalization or not. The flag can be set with "--setautoactivation y|n" using vgchange and lvchange and can be viewed with "lvs -o +lv_autoactivation". The setting defaults to being enabled.

The current lvm init script calls vgchange with "--activate y", forcing activation of all VGs and LVs, regardless of their autoactivation flag. During system initialization "--activate ay" should be used, to honor the autoactivation flag set on VGs and LVs.

Use case for this is, that a VG has PVs that are not always present. Disabling autoactivation on the respective LVs currently has no effect, causing the vgchange command and the init script to fail during system initialization.

Seems reasonable to me.
