tests: Create a regression-tests package for distribution

2013-09-19T16:28:44+00:00

As of today regression tests are an in-house breed, by making
it a new package and distributing it ensures larger set of
people use it and contribute to it. This can also be used
by any consumer/user to build their own environment for glusterfs
regression testing which is today limited only to 'upstream'
'glusterfs' releases and build.gluster.org

cli/glusterd: improve rebalance fix-layout status reporting

2013-09-19T16:22:36+00:00

Problem:
Currenly the CLI rebalance status command output does not indicate the
'type' of rebalance, i.e. whether a full rebalance or only a fix-layout
was carried out.

Fix: After the rebalance status of all peers is received by the
originator glusterd, alter it to reflect the type of rebalance
before passing it on to the CLI process.

glusterfsd: use-readdirp w/o arguments should not turn off readdirp

2013-09-10T04:41:41+00:00

`use-readdirp` has an optional argument in argp -
specifying just `--use-readdirp` command line should not
'turn off' readdirp, since that undermines the meaning
of such an argument.

cluster/dht: assign layout onto missing directories too

2013-09-09T21:58:09+00:00

The current self-healing algorithm is ignoring missing directories
for assigning new layout. When lookup() is racing against mkdir()
or when self-healing a half-done mkdir(), the layout assignment split
must happen based on the final number of directories, and not the
currently existing number of directories (because we finish mkdir()
of missing directories before hash layout assignment).

Without this fix, concurrent mkdir() and lookup() will step on
each others feet, create a messed up layout on disk, and end up
with different in-memory layouts.

Once two clients have different in-memory layouts, creation of
subdirectory will not arbitrate on the same hashed subvolume and will
result in GFID mismatch of the sub-directory.

glusterfsd: Round robin DNS should not be relied upon with

2013-09-06T22:56:34+00:00

config service availability for clients.

Backupvolfile server as it stands is slow and prone to errors
with mount script and its combination with RRDNS. Instead in
theory it should use all the available nodes in 'trusted pool'
by default (Right now we don't have a mechanism in place for
this)

Nevertheless this patch provides a scenario where a list of
volfile-server can be provided on command as shown below

-----------------------------------------------------------------
$ glusterfs -s server1 .. -s serverN --volfile-id= \
      
-----------------------------------------------------------------
                   OR
-----------------------------------------------------------------
$ mount -t glusterfs -obackup-volfile-servers=: \
      :...: :/ 
-----------------------------------------------------------------

Here ':' is used as a separator for mount script parsing

Now these will be remembered and recursively attempted for
fetching vol-file until exhausted. This would ensure that the
clients get 'volume' configs in a consistent manner avoiding the
need to poll through RRDNS.

nfs: persistent caching of connected NFS-clients

2013-08-28T13:54:44+00:00

Introduce /var/lib/glusterfs/nfs/rmtab to contain a list of NFS-clients
which have a volume mounted. The volume option 'nfs.mount-rmtab' can be
set to an alternative filename. When the file is located on shared
storage, multiple gNFS servers can use the same file to present a single
NFS-server.

This cache is read when a system administrator calls 'showmount -a' and
updated when an NFS-client calls MNT or UMNT from the MOUNT protocol.

Usage:
- create a volume for storing the shared rmtab file
- mount the volume on all storage servers, at the same location
- make sure that the volume is mounted at boot (add to /etc/fstab)
- place the rmtab file on the volume:
   # gluster volume set  nfs.mount-rmtab /
- any subsequent mount requests will add an entry to this file
- 'showmount -a' requests will return the NFS-clients using the cluster

Note:
The NFS-server does currently not support reconfigure(). When a
configuration option is set/changed, the NFS-server glusterfs process
gets restarted. This causes the active NFS-clients to be forgotten (the
entries are saved in the old rmtab, but we do not have a reference to
that file any more, so we can't re-add them). Therefor a re-mount done
by the NFS-clients is needed before they get listed in the rmtab again.
