Hi All,
After a recent update to gluster 3.5 we are having
some issues renaming files when root squashing is
enabled and the folder group permissions are not set to
write.
For example if I create a folder with the following
permissions
$ mkdir test
$ chmod g-w test
$ ls -l
drwxr-xr-x 2
dave dave 22 Jul 14 17:16 test
When I create a file within this folder, and
try to rename it I get a file permissions error.
$ cd test
$ touch asdf
$ mv asdf asdf2
mv: cannot move
‘asdf’ to ‘asdf2’: Permission denied
A strace on the mv command reveals the rename system
call fails with:
rename("asdf",
"asdf2") = -1 EACCES (Permission denied)
However I can copy the file and delete the old one
fine.
If I either disable gluster root squashing, or change
the test_dir folder group permission to write then I can
rename the file without any problems.
System details are:
Arch linux
System umask is set to 002
Distributed volume, 3 peers, 1 brick per peer.
Any help is much appreciated!
Dave
