Thanks Dan. Is there any preferred filesystem filesystem for the leveldb files? 
I understand that the filesystem should be of same type on both /var and ssd 
partition.
Should it be ext4, xfs, something else or doesn't matter?

I think it doesn’t matter.
We use xfs.

Cheers, Dan

2. Has any one used SSD devices for Monitors. If so, can you please share the 
details ? Any specific changes to the configuration files?

We use SSDs on our monitors — a spinning disk was not fast enough for leveldb 
and we observed monitor elections during heavy backfilling.
There’s no special configuration required, just mount the SSD on /var/lib/ceph

Cheers, Dan
