Hi All, I'm writing a small piece of code to call fsfreeze/unfreeze that can be invoked by a RADOS notify. I have the basic watch/notify functionality working but I need to be able to determine if the notify message is to freeze or unfreeze, or maybe something completely unrelated. I'm looking

Dear Gaurav, Ceph works best with more hardware. It is not really designed for small scale setups. Of course small setups can work for a PoC or testing, but I would not advise this for production. If you want to proceed however, have a good look the manuals or this mailinglist archive and do

[ceph-users] ceph cluster not reposnd

sorry guys, I solved the problem. The issue because high io wait on the local disk of the monitor servers. I migrate the local disks from raid1 to raid5 to get more io . (The leveldb stores on the local disks of the monitor servers and each change in the map requires update of the database)
