This is still a work in progress.

As of now, these things are done:
* Take the snapshot of the backend brick
* Create the new volume for the snapshot
* Create the brick and the client volfiles
* Store the snapshot related info in /var/lib/glusterd
* Create the snap object representing the snapshot

TODO:
Start the brick processes for the snapshot

glusterd: Volume locks and transaction specific opinfos

2013-10-10T07:13:47+00:00

With this patch we are replacing the existing cluster-wide
lock taken on glusterds across the cluster, with volume locks
which are also taken on glusterds across the cluster, but are
volume specific. So with the volume locks we are able to perform
more than one gluster operation at the same time, as long as the
operations are being performed on different volumes.

We maintain a global list of volume-locks (using a dict for a list)
where the key is the volume name, and which saves the uuid of the
originator glusterd. These locks are held and released per volume
transaction.

In order to acheive multiple gluster operations occuring at the
same time, we also separate opinfos in the op-state-machine, as a
part of this patch. To do so, we generate a unique transaction-id
(uuid) per gluster transaction. An opinfo is then associated with
this transaction id, which is used throughout the transaction. We
maintain a run-time global list(using a dict) of transaction-ids,
and their respective opinfos to achieve this.

libglusterfs: add glusterfs-acl.h to Makefile.am

2013-10-01T02:04:03+00:00

Without this, glusterfs-acl.h is left out of 'make dist'
and building RPM fails.

gNFS: Incorrect NFS ACL encoding for XFS

2013-09-29T23:54:37+00:00

Problem:
Incorrect NFS ACL encoding causes "system.posix_acl_default"
setxattr failure on bricks on XFS file system. XFS (potentially
others?) doesn't understand when the 0x10 prefix is added to the
ACL type field for default ACLs (which the Linux NFS client adds)
which causes setfacl()->setxattr() to fail silently. NFS client
adds NFS_ACL_DEFAULT(0x1000) for default ACL.

FIX:
Mask the prefix (added by NFS client) OFF, so the setfacl is not
rejected when it hits the FS.

core: block unused signals in created threads

2013-09-25T08:33:16+00:00

Block all signal except those which are set for explicit handling
in glusterfs_signals_setup(). Since thread spawning code in
libglusterfs and xlators can get called from application threads
when used through libgfapi, it is necessary to do this blocking.

logging: Expose set_log_file_path() in libglusterfs.

2013-09-24T19:00:54+00:00

This patch also changes the behavior of glfs_set_logging().
If logfile argument is not provided to glfs_set_logging(),
libgfapi uses set_log_file_path() to create a logfile.

parser: use private namespace 'graphyy' instead of 'yy'

2013-09-22T06:45:09+00:00

This can cause linker errors when accessing glusterfs through
libgfapi if the caller also uses a parser with 'yy' prefix.

rpcsvc: allocate large auxgid list on demand

2013-09-17T18:44:21+00:00

For rpc requests having large aux group list, allocate large list
on demand. Else use small static array by default.

Without this patch, glusterfsd allocates 140+MB of resident memory
just to get started and initialized.
