Hi, As it is my really first message here, here is a short description of me^Wmy project.
I'm a totally newbie. I'm currently playing with Ceph in order to discover it features. My project is to use it in a sort of friendnet based on small nodes connected via ADSL (xDSL) links. As a really first experience, I started a cluster with 3 nodes and a mon on a single machine. Specs are ridiculusly small: 256 MB of RAM, 2 OSDs on 8 GB USB keys and 1 OSD on 80 GB on LVM partition. My last experiment was a big failure. While trying to format a RBD partition (mapped on the same machine) I encountered a kernel panic. I tried twice, creating dedicated images and the same thing occured: kernel panic. The real matter is not the data loss, but the current situation : I have a pool with 3~4 images that I cannot delete nor map. test:~# rados ls --pool icwt rb.0.1071.74b0dc51.000000000000 ... partage.rbd ... rbd_directory rb.0.139d.2ae8944a.0000000000c0 rb.0.139d.2ae8944a.0000000000a0 # rbd info -p icwt partage --secret /etc/ceph/client.admin rbd: error opening image partage: (95) Operation not supported 2014-01-13 22:19:43.136065 b66c4740 -1 librbd: Error listing snapshots: (95) Operation not supported # rbd map icwt/partage --secret /etc/ceph/client.admin rbd: add failed: (34) Numerical result out of range test:~# rbd rm icwt/partage --secret /etc/ceph/client.admin 2014-01-13 22:22:03.458105 b679f740 -1 librbd: Error listing snapshots: (95) Operation not supported Removing image: 0% complete...failed. rbd: delete error: (95) Operation not supported 2014-01-13 22:22:03.503661 b679f740 -1 librbd: error getting id of image I imagine it is something really trivial, but I do not understand what's going wrong. Can someone give me a tip or something to read?
