By design you cannot have two filesystems sharing the
same log device.
The xfs(5) man page has an explanation on what each of
the different sections of an XFS filesystem are for...
The log section (or area, if it is internal to the data
section) is used to store changes to filesystem metadata
while the filesystem is running until those changes are
made to the data section. It is written sequentially dur-
ing normal operation and read only during mount. When
mounting a filesystem after a crash, the log is read to
complete operations that were in progress at the time of
the crash.
cheers.
