From: Pascal de Bruijn Date: Mon, 2 Mar 2020 07:49:50 +0000 (+0100) Subject: package/lvm2: lvmetad integration X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9889b8ce7fcef50fb5089f6e3e84b54f730d0ca6;p=buildroot.git package/lvm2: lvmetad integration lvmetad is usually combined with event-based system services that automatically run pvscan --cache on disks added or removed. This way, the cache is automatically updated with metadata from new disks when they appear. LVM udev rules and systemd services implement this automation. Automatic scanning is usually combined with automatic activation. For more information, see pvscan(8).
