Description

When trying to mount a pool multiple times (with different subdirectories) I get a consistent system hang.

Steps to repro:

  • Mount a subdirectory of the storage pool
    - on my system, it's 192.168.1.10:/home mounted to /home
  • Mount the root of the storage pool on a separate mount
    - on my system, it's 192.168.1.10:/ mounted to /tank
  • Try to list the root of the storage pool

The immediate hang makes it difficult to save the stack track anywhere, but I wrote down the function names in case that helps.

Process is ceph-msgr
ceph_dentry_release
<- d_free
<- d_kill
<- dput
<- splice_dentry
<- ceph_readdir_populate
<- handle_reply
<- dispatch

Should have mentioned - this is with the Ubuntu 10.10 desktop kernel, which is 2.6.35-22, I think.
