geo-rep: Fix invalid disk size in gverify.sh

2016-03-01T07:57:20+00:00

Problem:
        Due to the wrong interpretation of disk size, gverify.sh script
exits in between with error "integer expression expected".
This error can be observed, only if gverify.sh is run standalone.

Solution:
        Fix the interpretation of disk size.

Also, verify that master and slave's gluster version are same.

glusterd/geo-rep: Adding ssh-port option for geo-rep create

2015-11-18T19:33:37+00:00

Geo-replication uses default ssh port 22 for setup.
i.e., to distribute ssh keys to slaves. In container
environments, custom port number might be used.
Hence to support custom port number for ssh, option
is provided in geo-rep create command to take the
same.

gverify: Adding StrictHostKeyChecking=no for ssh verification

2015-06-13T06:28:06+00:00

Before actually checking the compatibility between master and
slave, gverify checks if there is a passwordless ssh connection
between master to slave.  So if the entry of the slave was not
present in 'known_hosts' file in master gverify used to complain
that passwordless ssh has not been setup. This used to happen
even if there is a passwordless ssh between master to slave.

This patch fixes the above problem by using StrictHostKeyChecking=no
while doing ssh to slave.

geo-rep/gverify: Ignore .trashcan while checking slave is empty.

2015-03-20T17:27:05+00:00

With trash translator, '.trashcan' is created in gluster volume
during init. So geo-rep create used to fail, with slave not
being empty. The gverify script should ignore '.trashcan' while
checking whether slave is empty.

Regression test portability: mktemp

2014-08-20T20:46:44+00:00

Linux mktemp accepts to run without a template, NetBSD mandates it. Since
the template option has the same syntax, add it everywhere. While there,
also do this in scripts outside of regression testing.

geo-rep/gverify: Never use ping to check for host reachability

2014-06-12T12:48:23+00:00

On many linux distributions with iptables enabled, ICMP traffic
is usually dropped even when port 22 is open for SSH service

So practically `ping` is an unreliable command

glusterd/geo-rep: Allow gverify.sh and S56glusterd-geo-rep-create-post.sh

2014-05-14T17:24:25+00:00

to operate for non-root privileged slave volume

Mounting the slave-volume on local node, to perform disk checks
in order to allow gverify.sh to operate for non-root privileged
slave volume

Allowing the hook script S56glusterd-geo-rep-create-post.sh
to operate for non-root privileged slave volume

Modified peer_add_secret_pub.in to accept username as argument
and add the pem keys to the users's_home_dir/.ssh/authorized_keys

Wrote set_geo_rep_pem_keys.sh which accepts username as argument
and copies the pem keys from the user's home directory to
$GLUSTERD_WORKING_DIR/geo-replication/ and then copies the keys
to other nodes in the cluster and add them to the respective
authorized keys. The script takes as argument the user name and
assumes that the user will be present in all the nodes in the
cluster. It is not needed for root.

To summarize:
For a privileged slave user, execute the following on master node as super user:
gluster system:: execute gsec_create
gluster volume geo-replication  [root@]:: create push_pem

For a non-privileged slave user execute the following on master node as super user:
gluster system:: execute gsec_create
gluster volume geo-replication  @:: create push_pem
then on the slave node execute the following as super user:
/usr/local/libexec/glusterfs/set_geo_rep_pem_keys.sh
