Felix,
do you combine your setup with clustering software? Or do you script a
live migration? I'm intrigued by how you handle the timing in the latter
case.
ah, I didn't make this really clear.
I haven't set this up with either live migration capabilities nor
pacemaker. All I have is a hot standby for manual recovery in case of a
primary node failure. Sorry.
I believe that for pacemaker, you would have both your nodes be primary
at all times (i.e., not use a master-slave set at all).
Not a thrilling perspective, I guess.
Cheers,
Felix
I see :-)
The project I'm engaging into does require things like live migration
and quick backup.
I guess the answer to my question would be to use a dual primary DRBD
setup with GFS or OCFS on top of and Pacemaker dealing with the
migrations. Backup could then be a matter of snapshot one of the DRBD
nodes. If DRBD is built on LVM, this should be easy (after an xm save).
thx again,
B.
