[Moosefs-users] Groups and permissions bug

[Samuel H. O. N. <sam...@ol...>]

Hi all,

I think we found a bug in MooseFS in the POSIX permissions process when 
trying to write/access with a user who is member of multiple groups.

Here the problem:

*On the disk (without MooseFS):*

/root@as-001/:/home# ls -l
total 0
drwxrwsr-x 5 perso-10431 perso-10431 4096 Apr 27 15:33 perso-10431
/root@as-001/:/home# su sam
/sam@as-001/:/home$ id
uid=11458(sam) gid=11458(Samuel Hassine) groups=11458(Samuel 
Hassine),10431(perso-10431),10433(perso-10433)
/sam@as-001/:/home$ touch perso-10431/test

This is working well.

*On the MooseFS partition:*
/
root@as-001/:/dns/com/anotherservice/dev/Apps$ ls -l
total 0
drwxrwsr-x 5 perso-10431 perso-10431 0 Apr 27 15:22 perso-10431
/sam@as-001/:/dns/com/anotherservice/dev/Apps$ id
uid=11458(sam) gid=11458(Samuel Hassine) groups=11458(Samuel 
Hassine),10431(perso-10431),10433(perso-10433)
/sam@as-001/:/dns/com/anotherservice/dev/Apps$ touch perso-10431/test
touch: cannot touch `perso-10431/test': Permission denied

This is not working (permission denied).

Is it a already known bug? If yes, can I fix it easilly?

Thanks for your help.

Best regards.
