<br>
quick question about snapshot mounting: Were there changes in 3.12 that<br>
were not mentioned in the release notes for snapshot mounting?<br>
I recently upgraded from 3.10 to 3.12 on CentOS (using<br>
centos-release-gluster312). The upgrade worked flawless. The volume<br>
works fine too. But mounting a snapshot fails with those two error messages:<br>

<br>
Up to the mounting everything works as before:<br>

# gluster snapshot activate test<br>
# gluster snapshot info test<br>

Google was no help so far. Since the mount worked before the upgrade I'm<br>
puzzled. What am I missing?<br>
<br>
Thanks a lot!<br>
