cluster/afr: unwind instead of returning directly if no open is required on any child

2011-11-04T16:55:31+00:00

Currently if no open is required on any child of replicate, we are
returning directly instead of unwinding and returning. This is leading
to the frame loss, which results in application hang. Unwind and then
return if no open is to be done on any child.

nfs: do not return -1 (error), if the transmission buffer list is empty

2011-11-04T12:37:17+00:00

In the rpc implementation of nfs suppose the transmission buffer list
is empty for the nfs server, -1 is being returned which is treated as
an error and the socket fd is closed to handle it. Because of this the
reply submission of the server will be failed. Thus if the transmission
buffer list is empty error should not be returned.

Rotating geo-replication master/monitor log files from cli.
On invocation, the log file for a given master-slave session
is backed up with the current timestamp suffixed to the file
name and signal is sent to gsyncd to start logging to a new
log file.

Sample commands:

* Rotate log file for this : session:
gluster volume geo-replication   log-rotate

* Rotate log files for all session for master volume 
gluster volume geo-replication  log-rotate

* Rotate log files for all sessions:
gluster volume geo-replication log-rotate

performance/write-behind: queue setattr fop with writes always.

2011-11-03T13:18:03+00:00

stat returned in setattr_cbk can be cached by the kernel. Hence it is
always necessary that we return correct stat, which implies that setattr
should not be out of order with respect to write fops.

stripe readv_cbk: Propogate the correct size and blk cnt in stbuf

2011-11-03T13:16:37+00:00

We were passing the stbuf returned by the first child/index, which
can be different to the size/blocks returned by stat. This led to
applications viewing the file as being truncated.

The stbuf size needs to be the largest of all results, and blocks
the aggregation from all subvolumes. (similar to stat)
