It would need to be set to 1
Hello David,
so in a 3 node Cluster how should I set min_size if I want that 2 nodes could fail?

Hi,
This is probably the min_size on your cephfs data and/or metadata pool. I believe the default is 2, if you have less than 2 replicas available I/O will stop. See: http://docs.ceph.com/docs/master/rados/operations/pools/#set-the-number-of-object-replicas

Hello,
I'm still very new to Ceph. I've created a small test Cluster.
ceph-node1
osd0
osd1
osd2
ceph-node2
osd3
osd4
osd5
ceph-node3
osd6
osd7
osd8
My pool for CephFS has a replication count of 3. I've powered of 2 nodes(6 OSDs went down) and my cluster status became critical and my ceph clients(cephfs) run into a timeout. My data(I had only one file on my pool) was still on one of the active OSDs. Is this the expected behaviour that the Cluster status became critical and my Clients run into a timeout?
Many thanks for your feedback.
