# The default sanlock configuration requires the management
|
|
# application to manually define <lease> elements in the
|
|
# guest configuration, typically one lease per disk. An
|
|
# alternative is to enable "auto disk lease" mode. In this
|
|
# usage, libvirt will automatically create a lockspace and
|
|
# lease for each fully qualified disk path. This works if
|
|
# you are able to ensure stable, unique disk paths across
|
|
# all hosts in a network.
|
|
#
|
|
# Uncomment this to enable automatic lease creation.
|
|
#
|
|
# NB: the 'host_id' parameter must be set if enabling this
|
|
#
|
|
#auto_disk_leases = 1

#
|
|
# The default location in which lockspaces are created when
|
|
# automatic lease creation is enabled. For each unique disk
|
|
# path, a file $LEASE_DIR/NNNNNNNNNNNNNN will be created
|
|
# where 'NNNNNNNNNNNNNN' is the MD5 hash of the disk path.
|
|
#
|
|
# If this directory is on local storage, it will only protect
|
|
# against a VM being started twice on the same host, or two
|
|
# guests on the same host using the same disk path. If the
|
|
# directory is on NFS, then it can protect against concurrent
|
|
# usage across all hosts which have the share mounted.
|
|
#
|
|
# Recommendation is to just mount this default location as
|
|
# an NFS volume. Uncomment this, if you would prefer the mount
|
|
# point to be somewhere else. Moreover, please make sure
|
|
# sanlock daemon can access the specified path.

# at 'disk_lease_dir' *MUST* be given a different host ID.

# Sanlock is able to kill qemu processes on IO timeout. By its internal
