_______________________________________________Hi Cepher,
I have created a pool and trying to create rbd image on the ceph client, while mapping the rbd image it fails as:
ubuntu@shambhucephnode0:~$ sudo rbd map pool1-img1 -p pool1
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
so I checked the dmesg as suggested:
ubuntu@shambhucephnode0:~$ dmesg | tail
