Little udev-triggered automatic volume expansion for VMs
This script and udev rule 'listen' for new attached block devices on a system and automatically add them to an LVM volume group or specific logical volume per the user's preference.
The autolv_installer.bsx deploys the changes/script and provides the initial user configuration. (see release notes for installation one-liner)
A default configuration for Turnkey Linux targeting the turnkey volume group and root logical volume is provided, or you can select an existing volume
group or define a new one, then optionally, you can specify a target logical volume.
/etc/udev/rules.d/10-autolvm.rules
/usr/sbin/autolvm
Once installed and configured, no action is required from the user. autolvm can be run to gather information or reconfigure the automatically expanded target at any time.
autolvm [ --help | -h | -? ] Provides usage and examples
autolvm --list Displays the current volume group (and optionally logical volume) target
autolvm [ VG_name ] [ LV_name ] Reconfigures the target(s) to the arguments provided
With no arguments, --list will display the current selection(s) and offer reconfiguration.
From the build_install folder:
chmod +x build && ./build
This will produce autolv_installer.bsx in the build_install folder.
