[Gluster-devel] Bug with group permissions

[Raghavendra G]

Hi Geoff,
I tried to reproduce your problem with glusterfs--mainline--2.5--patch-545,

files? Also what is the fuse version you are using?

regards,

A centipede was happy quite, until a toad in fun,
Said, "Prey, which leg comes after which?",
This raised his doubts to such a pitch,
He fell flat into the ditch,
Not knowing how to run.
