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.

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.

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.

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.

rpc: fix typo which refers glibc macro

A typo which read MAX_AUTH_BYTES instead of GF_MAX_AUTH_BYTES was
picking the value 400 instead of the larger 2048. This causes
failures when number of aux group ids is a large number.

libglusterfs/client_t client_t implementation, phase 1

2013-07-30T05:22:21+00:00

Implementation of client_t

The feature page for client_t is at
http://www.gluster.org/community/documentation/index.php/Planning34/client_t

In addition to adding libglusterfs/client_t.[ch] it also extracts/moves
the locktable functionality from xlators/protocol/server to libglusterfs,
where it is used; thus it may now be shared by other xlators too.

This patch is large as it is. Hooking up the state dump is left to do
in phase 2 of this patch set.

(N.B. this change/patch-set supercedes previous change 3689, which was
corrupted during a rebase. That change will be abandoned.)

glusterd/cli changes for distributed geo-rep

2013-07-26T20:19:18+00:00

Commands:
gluster system:: execute gsec_create
gluster volume geo-rep   create [push-pem] [force]
gluster volume geo-rep   start [force]
gluster volume geo-rep   stop [force]
gluster volume geo-rep   delete
gluster volume geo-rep   config
gluster volume geo-rep   status

The geo-replication is distributed. The session will be created, and
gsyncd will be spawned on all relevant nodes, instead of only one
node.

geo-rep: Collecting status detail related data

Added persistent store for saving information about
TotalFilesSynced, TotalSyncTime, TotalBytesSynced

Changes in the status information in socket:
Existing(Ex):
FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;

New(Ex):
FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;SyncTime=0.69978;
TotalSyncTime=2.890044;TotalFilesSynced=6;TotalBytesSynced=143640;
