Hello Malahal,
Thanks for reply.
I tried that fix, But I am seeing following messages from solaris
client. This is bit random issue.
rm: WARNING: A subdirectory of /mnt/vdbench2/bigfileset/00000003 was
moved or linked to another directory during the execution of rm
rm: Unable to remove directory
/mnt/vdbench2/bigfileset/00000003/00000004: No such file or directory

The filesystem is not updated by any other than Ganesha server itself.
And this issue only comes on Solaris, I have not see it on Linux.
Thank you,
Tushar
