Great to hear.

Running xfs_freeze -f before the snapshot is taken is very important, as
it ensures the filesystem will not be modified while the snapshot is
taken. Snapshots may be corrupted if the filesystem is not frozen.

xfs_freeze -f may take some time, as it waits for all outstanding
transactions to complete before returning, however if it is hanging
indefinately you should report the bug to xfs at oss.sgi.com with your
kernel and xfs-progs versions.
