Description

With this libcephfs test: https://gist.github.com/3762534

The first mds crashes during shutdown. The ceph cluster is configured with 3 mds servers (the default for vstart.sh).

Verified that this is only an issue with an empty component in the path (related to #2285).

The getattr segfault is actually from the second mount call in the client test.

  • Project changed from Ceph to CephFS
  • Category deleted (1)

Bulk updating project=ceph category=mds bugs so that I can remove the MDS category from the Ceph project to avoid confusion.
