Description shylesh 2014-02-05 07:02:29 UTC

Description of problem:
If a file has setuid bit set and if it is migrated through remove-brick then setuid bit disappears after migration.

Version-Release number of selected component (if applicable):

3.4.0.59rhs-1.el6_4.x86_64
How reproducible:
always

Steps to Reproduce:
1.creted a 6x2  distributed-replicate volume
2. added a new user test and created some files on the mount point as test user
3. set the sticky bit and setuid bit
chmod +t <file> & chmod +s <file>
4. permission becomes 
-rwSrwSr-T
5. Now remove one of the pair using remove-brick command
gluster volume remove-brick <vol> <brick> start 
6. once the migration is complete commit it 
7. check the permissions on the mount point

Actual results:

permission of the file got changed to  -rw-rwSr-T.

so setuid bit is missing for user

Followed the repro steps and checked the permissions of the file after the migration. The permissions are intact. Closing the bug.
