[Gluster-devel] gluster 3.6.2 ls issues

[David F. Robinson]

Cancel this issue.  I found the problem.  Explanation below...

We use active directory to manage our user accounts; however, open sssd 
doesn't seem to play well with gluster.  When I turn it on, the cpu load 
shoots up to between 80-100% and stays there (previously submitted bug 
report).  So, we I did on my gluster machines to keep the uid/gid 
updated (required due to server.manage-gids=on), is write a script that 
start opensssd, grabs all of the groups/users from the server, parses 
out the /etc/group and /etc/passwd file, and then shuts down sssd.  I 
didn't realize that sssd uses the locally cached file.  My script was 
running faster than sssd was updating the cache file, so this particular 
user wasn't in the SBIR group on all of the machines.  He was in that 
group on gfs01a, but not on gfs01b (replica pair) or gfs02a/02b.  I 
guess this gave him enough permission to cd into the directory, but for 
some strange reason he couldn't do an "ls" and have the directory name 
show up.

The only reason I do any of this is because I had to use 
server.manage-gids to overcome the 32-group limitation.  This requires 
that my storage system have all of the user accounts and groups.  The 
preferred option would be to simply use sssd on my storage systems, but 
it doesn't seem to play well with gluster.
