HEADS UP - last minute (non-bug-fix) HAMMER change to master/slave operation
I've decided to remove some confusion from the HAMMER utility, and also
remove some of the master id code from the filesystem, which was
designed for multi-master mode but really added confusion to the
whole master-slave setup since we don't support multi-master mode
in this release.
PFS's will now only be master or slave, there will be no master id
(0-15) setting and there will not be a no-mirror mode. A single
whole-mount master id or no-mirror mode can be specified at mount
time which is how I had it originally. That way the master_id is
out of sight and out of mind for the release.
I am also removing the 'master' and 'slave' options to pfs-update,
simplifying the PFS features. Now you can create a master, create a
slave, upgrade a slave to a master, or downgrade a master to a slave.
The confusing 'no-mirror', 'master=' and 'slave' options have been
I'll update the hammer.5 and hammer.8 docs appropriately, as well.
