linux ACL question
Posted on 2011-03-09
I have created a file called lab2 and gave access to userID mark, but after su to mark, I don't have permission to write contents on lab2 file. What am I missing here?
getfacl lab2
# file: lab2
# owner: ghuru
# group: ghuru
user::rw-
user:mark:rw-
group::rw-
mask::rw-
other::r--
getfacl lab2
# file: lab2
# owner: ghuru
# group: ghuru
user::rw-
user:mark:rw-
group::rw-
mask::rw-
other::r--

[root@localhost ghuru]# ls -l lab2
-rw-rw-r--+ 2 ghuru ghuru 0 Mar 9 19:03 lab2
Is this file system should mount with ACL option?

Yes, in your fstab, is it mouted with acl in the options?
If not try doing this
mount -o remount,rw,acl -t ext3 /dev/... /mount/pt
Also for now, try doing chmod 777 lab2, just to make sure

mount -o remount,rw,acl -t ext3 /dev/... /mount/pt

Just an FYI - Sometimes you don't need the acl option in fstab if it is specified in the filesystem's default mount options. You can check with dumpe2fs:
# dumpe2fs /dev/sda1 | grep mount
dumpe2fs 1.39 (29-May-2006)
Last mounted on: <not available>
Default mount options: user_xattr acl
Last mount time: Thu Feb 3 09:21:52 2011
Maximum mount count: -1
# dumpe2fs /dev/sda1 | grep mount
dumpe2fs 1.39 (29-May-2006)
Last mounted on: <not available>
Default mount options: user_xattr acl
Last mount time: Thu Feb 3 09:21:52 2011
Maximum mount count: -1
