I have a system with a bunch or ram that I want to remain the active MDS
but still have a backup.
This config doesn't seem to be working. I can make linuscs92 the active
by stopping and starting the mds on linuscs95. It would be nice for
linuscs92 to be the active from the start.
[mds.linuscs95]
host = linuscs95
mds standby replay = true
mds standby for name = linuscs92
Also about disk write cache.
If the Data center, servers and storage units are backed by redundant
power sources, Batteries and a generator. Is the concern for data loss
less?
Any one turn disk write cache on and see a great improvement?
Thanks
Matt
