Hi Kumar “Clock skew” is just a warning and should not related to this problem. But its pretty easy to fix this warning either by setting up NTP on all Ceph cluster nodes or by adding mon clock drift warn backoff = <Seconds> into ceph.conf (do not do this in production)
WRT to your second problem , try to check out cinder volume logs and scheduler logs , you would surely find something there. If not try increasing debug level of cinder and check for some clues. - Karan Singh - On 10 Jun 2014, at 09:53, yalla.gnan.ku...@accenture.com wrote: > Hi All, > > > I have four node ceph cluster.
