[ceph-users] Hanging ceph client

2014-08-21 Thread Damien Churchill
Hi, On a freshly created 4 node cluster I'm struggling to get the 4th node to create correctly. ceph-deploy is unable to create the OSDs on it and when logging in to the node and attempting to run `ceph -s` manually (after copying the client.admin keyring) with debug parameters it ends up hanging

[ceph-users] MDS cluster degraded after upgrade to dumpling

2013-08-20 Thread Damien Churchill
Hi, After upgrading to dumpling I appear unable to get the mds cluster running. The active server just sits in the rejoin state spinning and causing lots of i/o on the osds. Looking at the logs it appears to be going through checking a vast number of missing inodes. 2013-08-20 13:50:29.129624 7fd

[ceph-users] RBD & Windows Failover Clustering

2013-10-22 Thread Damien Churchill
Hi, I was wondering if anyone has had any experience in attempting to use a RBD volume as a clustered drive in Windows Failover Clustering? I'm getting the impression that it won't work since it needs to be either an iSCSI LUN or a SCSI LUN. Thanks, Damien
