[Gluster-devel] showmount reports many entries (Re: glusterfs-3.3.0qa39 released)

[Tomoaki Sato]

Vijay,

I have been testing gluster-3.3.0qa39 NFS with 4 CentOS 6.2 NFS clients.
The test set is like following:
1) All 4 clients mount 64 directories. (total 192 directories)
2) 192 procs runs on the 4 clients. each proc create a new unique file and write 1GB data to the file. (total 192GB)
3) All 4 clients umount 64 directories.

The test finished successfully but showmount command reported many entries in spite of there were no NFS clients remain.
Then I have restarted gluster related daemons.
After restarting, showmount command reports no entries.
Any insight into this is much appreciated.
