We have an occasional problem that prevents deletion of certain GlusterFS mounted files. See the following, for example, with corresponding log file message. kevin at cd /glusterfs/atmos/users/kih/ECHAM5/TS4-TEMP kevin at 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. [root at nemo1 TS4-TEMP]# cat /etc/redhat-release CentOS release 5.5 (Final) [root at 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 [root at 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.
