[Gluster-users] AUX GID > 16

Mon May 7 18:56:05 UTC 2012

Hi Anush,

This is how I see the error. I added myself into more than 16 posix 
groups  and I start seeing the "Transport endpoint is not connected" 
error, and could no longer access the gluster file system anymore. I 
have no problem when using another user (tstopr) that belongs to less 
than 16 posix groups. Both server and client machines are running 
RHEL5.8, kernel version 2.6.18-308.1.1, and glusterfs 3.3.0beta3-1 .

Under 3.2.6-1, I could at least see the file system content as both 
users. Of couse I have problem with group permissions because of the rpc 
16 gid limit.
