We have an occasional problem that prevents deletion of certain GlusterFS mounted files. See the following, for example, with corresponding log file message.

ke...@cd /glusterfs/atmos/users/kih/ECHAM5/TS4-TEMP
ke...@rm HYBRID_TEMP_207212
rm: cannot remove `HYBRID_TEMP_207212': Invalid argument

[2010-12-28 00:59:04.298331] W [fuse-bridge.c:888:fuse_unlink_cbk] glusterfs-fuse: 3997: UNLINK() /users/kih/ECHAM5/TS4-TEMP/HYBRID_TEMP_207212 => -1 (Invalid argument)

The file was deleted without error on a machine where the volume was mounted via NFS. I have four compute servers that are using the GlusterFS client for performance reasons. Operating system and GlusterFS package details are as follows.

[r...@nemo1 TS4-TEMP]# cat /etc/redhat-release
CentOS release 5.5 (Final)
[r...@nemo1 TS4-TEMP]# uname -a
Linux nemo1.nerc-essc.ac.uk 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:14 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
[r...@nemo1 TS4-TEMP]# rpm -qa | grep -i gluster
glusterfs-fuse-3.1.1-1
glusterfs-core-3.1.1-1

Is there anything I can do to stop this from happening, other than using NFS instead of GlusterFS client?

-Dan.
