The docs recommend an MDS volume around 1-2% of the size of your total data
volume.
There?s a lot of useful information in the manual about sizing, etc., so
you?re probably better off reading them to see what suits your environment ?
but the 1-2% rule of thumb nonetheless applies.
The key element if you?re setting up an active/passive MDS pair is that you
need to be able to see the same device from both MDS nodes; the active one
will mount it, the passive one will wait until it?s needed (i.e. the active
MDS encounters a failure).
It?s essential that they not mount it simultaneously, though, or wicked
corruption is likely to occur.
