This is the second bugfix release for the v0.72.x Emperor series. We
have fixed a hang in radosgw, and fixed (again) a problem with monitor
CLI compatiblity with mixed version monitors. (In the future this
will no longer be a problem.)
Upgrading:
* The JSON schema for the 'osd pool set ...' com
This release includes a few critical bug fixes for the radosgw, including
a fix for hanging operations on large objects. There are also several bug
fixes for radosgw multi-site replications, and a few backported features.
Also, notably, the osd perf command (which dumps recent performance

So you get the capacity of one machine.

I think my wording was a bit misleading in my last message. Instead of
"no re-balancing will happen", I should have said that no OSDs will be
marked out of the cluster with the noout flag set.

It is also useful to mention that you can set the noout flag when doing
maintenance of any given length needs to exceeds the 'mon osd down out

$ ceph osd set noout

$ ceph osd unset noout
** normal re-balancing rules will resume **

Well, 1GB is really the minimum. As Mark suggested, go for 64GB since
that probably isn't the most expensive par

What has this have to do with ceph?
You can create a virtual machine with as many resources as a compute node has.
Since you can have "unlimited" virtual cores and also, using swap
space "unlimited" RAM, we could say "yes" to your question.
But if you are planning to use that machine for anythin
