geo-rep / gsyncd: fix cleanup of temporary mounts

2012-03-09T14:14:22+00:00

The "finally" clause that was meant to cleanup after the
temp mount has not covered the case of getting signalled
(eg. by monitor, upon worker timing out).

So here we "outsource" the cleanup to an ephemeral child process.
Child calls setsid(2) so it won't be bothered by internal process
management. We use a pipe in between worker and the cleanup child;
when child sees the worker end getting closed, it performs the cleanup.
Worker end can get closed either because worker closes it (normal case),
or because worker has terminated (faulty case) -- thus as bonus, we get
a nice uniform handling with no need to differentiate between normal and
faulty cases.

The faulty case that was seen IRL -- ie., users of maintainance mounts
hang in chdir(2) to mount point -- can be simulated for testing purposes
by applying the following patch:

geo-rep / syncdaemon: make the timeout for establishing the connection to slave configurable

2012-03-01T17:28:20+00:00

It can be set through the connection-timeout tunable but we keep it hidden,
intended as a workaround for some special scenarios not for general use.

cli: add geo-replication log-rotate command

2011-11-04T09:06:44+00:00

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
