Hi guys,
The "librbd: Error listing snapshots: (95) Operation not supported"
issue has been resolved, the root cause is when I deployed the OSD, I
just copy /usr/local/bin/* from MON-MDS node to the OSD, not include the
/usr/lib/rados-classes. So I re-transfer the /usr/lib/rados-classes
folder of MON-MDS node to OSD's, it works after this:
root@~# rbd --image odm-kvm-img -p mypool info
rbd image 'odm-kvm-img':
size 10240 MB in 2560 objects
order 22 (4096 KB objects)
block_name_prefix: rb.0.1217.6b8b4567
format: 1
BRs,
Dennis

Hi,
A different error msg after your suggestion --

I create the "odm-kvm-img" with this command:
root@~# rbd create odm-kvm-img --size 10240 --pool mypool

Subject: rbd command error "librbd::ImageCtx: error
finding header"
Hi list,
I am using a ceph cluster (version 0.56.4) with all nodes (mon, mds,
osd...) deployed in the RHEL 6 distro, the client is based on Ubuntu
12.10.
Now I am confused by a strange issue, seems the issue has been asked
before by google but no a clear answer for it. The specific details as
below--
in the client side, I want to create a rbd image, so I run the commands:
root@~# ceph osd pool create mypool 100 100
pool 'mypool' created
root@~# rbd ls -p mypool
odm-kvm-img
root@~# rbd --image odm-kvm-img info
rbd: error opening image 2013-04-24 10:43:42.800917 7fdb47d76780 -1
librbd::ImageCtx: error finding header: (2) No such file or
directoryodm-kvm-img:
(2) No such file or directory
So I tried those steps followed according the goolged:
root@~# rados ls -p mypool
odm-kvm-img.rbd
rbd_directory
root@~# rbd info odm-kvm-img.rbd
rbd: error opening image 2013-04-24 10:54:19.468770 7f8332dea780 -1
librbd::ImageCtx: error finding header: (2) No such file or directory
odm-kvm-img.rbd: (2) No such file or directory
odm-kvm-img.rbd is showed by 'rados ls' command and it's there, but why
I get an error when run the 'rbd info' command upon odm-kvm-img.rbd?
does anybody can be help about this?
BRs,
Dennis
