Hi Guido,I am running ceph version 0.39-37-g54758ab (commit:54758abccf429122c1bc3bce6d01bc33f1cfe238) on my cluster and I do not see this problem. Do you use the qemu rbd block driver or the kernel mount?
How did you install ceph, via the packages? -martin Am 15.12.2011 16:45, schrieb Guido Winkelmann:

I found that read access to some of the rbd images, or parts of some of them sometimes blocks indefinitely, usually after the image has been sitting around untouched for a while, for example over night. This has the effect that virtual machines that try to access their disks as well as rbd commands like "rbd cp" will just hang indefinitely. I found that these blocks can usually be "fixed" by restarting one of the> osds. The last time this happened, ceph -s reported one of the osds to be in state "active+clean+scrubbing". (I'm afraid I don't have the complete output from ceph -s anymore.) Does anybody have any idea what could be going wrong here?I think it's fixed in v0.39I'm already using 0.39, so, no.
