[Gluster-users] GlusterFS 3.1.1: "Permission denied" and "No such file or directory"

[Pranith Kumar. Karampuri]

To confirm the "Permission Denied" problem you are facing is indeed BUG 2296 following conditions should be met:
1) mount is fuse mount.
2) access-control translator should be present on top of the posix translator in the brick volfile.

you can see the reports of the following bugs for "Permission Denied on Fuse mount":

chown -R user:primary-group is a workaround that should fix the problem for now.

Hi Pranith and all,

I am not entirely sure what you mean by "how to trigger" the second problem.

This problem always occurs. I simply create a folder called test and 
perform an rm -rf on this folder. I get the error message

rm: cannot remove directory `test/': No such file or directory

but the folder vanishes anyway.

About the first problem again: When you say, non-primary group 
membership is treated as "others", this can't explain, as far as I 
understand, why sometimes writing into the very same directoy works and 
sometimes it fails. By the way: where can I see the bug reports?

Issuing a chown -R <user>:<primary_group> should resolve these issues, 
shouldn't it?

Thanks for your help,
Daniel
