Surprisingly, augtool get (or print) returns "path = value" while we are only interested in the value. We need to remove the "path = " part from the augtool's output. The following is an example of the augtool command as used in virt-sanlock-cleanup script: $ augtool get /files/etc/libvirt/qemu-sanlock.conf/disk_lease_dir /files/etc/libvirt/qemu-sanlock.conf/disk_lease_dir = /var/lib/libvirt/sanlock

=head1 NAME
|
|
|
|
virt-sanlock-cleanup - remove stale sanlock resource lease files
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
virt-sanlock-cleanup
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This tool removes any resource lease files created by the sanlock
|
|
lock manager plugin. The resource lease files only need to exist
|
|
on disks when a guest using the resource is active. This script
|
|
reclaims the disk space used by resources which are not currently
|
|
active.
|
|
|
|
=head1 EXIT STATUS
|
|
|
|
Upon successful processing of leases cleanup, an exit status
|
|
of 0 will be set. Upon fatal error a non-zero status will
|
|
be set.
