features/quota: Add the quota config xattr to newly added brick

2013-11-26T19:57:11+00:00

Issue:
Quota directory limit configuration is stored in the xattrs. When a new brick
is added these 'limit-set' xattrs have to be created to the directory in the
new brick. This is done by the dht directory healing when the directory is
created in the new brick. Since 'root' directory is already created DHT doesn't
heal the limit-set xattr root.

Solution:
When the add-brick command is issued run the below hook script to heal the
'limit-set' xattr. The hook script does the following only if limit is
configured on root.
    1. Create an auxiliary mount.
    2. getxattr 'limit-set' on the root
    3. setxattr the same value on the root
But this script needs the volume to be started to make the auxiliary mount.

To handle the case when the add-brick is issued when the volume was stopped,
symlink is created by the 'master' script to the corresponding location and
these two are by default disabled.

So, a 'master' script is added in the add-brick/pre. When add-brick command is
issued, it enables one of the scripts mentioned above based on the condition,
    if volume is started - enable add-brick/post script
    else                 - enable start/post script
After the actual script completes its job, it disables itself.

Note:
The enabling and disabling of the script is based on the glusterd's logic, that
it only runs the scripts which starts its name with 'S'. So,
    Enable     - symlink the file to 'S'*
    Disable    - unlink the symlink.

extras/hookscripts: Fix the multiple entries in smb.conf problem.

2013-10-08T16:22:00+00:00

Problem:
1. Force starts and user.smb sets were adding multiple entries to
the smb.conf file for the same volume.
Make a check for the entry and search with exact name.

2. Again, while deleting the share name from smb.conf search with
exact name so that volumes with names which are substrings of ones to
be deleted don't get deleted.

3. We don't need to use a tmp file while using sed -i, fixed that.

hookscripts: Changes in hook scripts to make it work on all Linux/GNU distribution

2013-10-05T00:05:35+00:00

Removed the hard coded values for smb.conf, smb logfile location and smbd.pid.
The current hook scripts also work for manully compiled (make, make install)
instance of gluster and Samba. But we have to manually copy the hook scripts
to respective locations.
