nfs: AUTH support for exported sub-directories

2013-07-10T05:55:12+00:00

Problem: NFS allows exporting subdirectories but there is not support for
providing AUTH on per directory basis.

Fix: Modified nfs.export-dir to include AUTH parameters
 e.g. nfs.export-dir "/dir1(10.1.1.2),/dir2(10.1.1.0/24|host1)

During mount operation NFS will check if the IP from where the connection is made
is configured in the AUTH parameter, else the mount operation will fail with
EACCES error.

Updated admin-guide and volume set help message.

posix: add a simple health-checker

2013-07-04T05:34:54+00:00

Goal of this health-checker is to detect fatal issues of the underlying
storage that is used for exporting a brick. The current implementation
requires the filesystem to detect the storage error, after which it will
notify the parent xlators and exit the glusterfsd (brick) process to
prevent further troubles.

The interval the health-check runs can be configured per volume with the
storage.health-check-interval option. The default interval is 30
seconds.

It is not trivial to write an automated test-case with the current
prove-framework. These are the manual steps that can be done to verify
the functionality:

- setup a Logical Volume (/dev/bz970960/xfs) and format is as XFS for
  brick usage

- create a volume with the one brick

    # gluster volume create failing_xfs glufs1:/bricks/failing_xfs/data
    # gluster volume start failing_xfs

- mount the volume and verify the functionality

- make the storage fail (use device-mapper, or pull disks)

    # dmsetup table
    ..
    bz970960-xfs: 0 196608 linear 7:0 2048

    # echo 0  196608 error > dmsetup-error-target
    # dmsetup load bz970960-xfs dmsetup-error-target
    # dmsetup resume bz970960-xfs

    # dmsetup table
    ...
    bz970960-xfs: 0 196608 error

- notice the errors caught by syslog:

- these errors are in the log of the brick as well:

- the glusterfsd process has exited correctly:
