Hi Storm,

Hello Eneko,
maybe I am paranoid, but I already experienced this situation when pgs
are unavailable until you fix the node/osd on which the missing pg is
on with replica=3 in 7 node cluster, with a failing osd on one up node
and two other nodes down.
Also have in mind that the cluster will be really slow when a lot of
nodes fail and recovery can take a long time...
So better be prepared.
As admin I never want to be responsible for any dataloss.
best regards and better be paranoid (always expect the worst case
scenario to happen, as it will)
Yes, but I think you should check you procedures so that you don't have
two nodes down. If you check ceph-user mailing list, almost nobody is
using size=4, much less for clusters so small.
But hey, if the budget and performance overhead is good for you, that's
your decisión (and I concur that it's more secure!)
Regards!
