Description
Hi,
Will someone please assist, I am trying to map image and this happens:
cluster-admin@nodeB:~/.ssh/ceph-cluster$ rbd map data_01 --pool data
rbd: sysfs write failed
In some cases useful info is found in syslog - try "dmesg | tail" or so.
rbd: map failed: (13) Permission denied
If someone could help it would be great
cluster-admin@nodeB:~/.ssh/ceph-cluster$ ceph -v
ceph version 10.2.1 (3a66dd4f30852819c1bdaa8ec23c795d4ad77269)
cluster-admin@nodeB:~/.ssh/ceph-cluster$ lsb_release -r
Release: 14.04
- Project changed from rbd to Linux kernel client
- Status changed from New to Need More Info
Did you check the output from dmesg?
All I see in dmesg is :
cluster-admin@nodeB:~/.ssh/ceph-cluster$ dmesg |grep ceph
[144467.750580] init: ceph-osd (ceph/7) main process (15881) killed by KILL signal

cluster-admin@nodeB:~/.ssh/ceph-cluster$
It looks like a session is opened when I run the commands after restarting ceph:
cluster-admin@nodeB:~/.ssh/ceph-cluster$ rbd map data_01 --pool data
rbd: sysfs write failed
Hi,
I disabled the "exclusive-lock, object-map, fast-diff,
deep-flatten" features on the image.
I can map image now. you can close the ticket

Kernels starting with 4.6 output an error to dmesg.
Newer rbd tool also prints a helpful message:
$ sudo rbd map foo
rbd: sysfs write failed
RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable".
In some cases useful info is found in syslog - try "dmesg | tail" or so.
rbd: map failed: (6) No such device or address
