Re: Mounting Ceph RBD image to XenServer 7 as SR

Mike Jacobacci <mikej@xxxxxxxxxx> · Thu, 30 Jun 2016 19:27:05 -0700

Thanks Jake!  I enabled the epel 7 repo and was able to get ceph-common installed.  Here is what happens when I try to map the drive:
rbd map rbd/enterprise-vm0 --name client.admin -m mon0 -k /etc/ceph/ceph.client.admin.keyring 
rbd: sysfs write failed
In some cases useful info is found in syslog - try "dmesg | tail" or so.
rbd: map failed: (5) Input/output error

dmesg | tail:

Also, when I enabled the cents repo, there were no updates… I am going to try the 7.2.1511 repo next.
