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.

feature/glusterfind: A tool to find incremental changes

2015-03-18T09:54:25+00:00

Documentation is available in patch:
http://review.gluster.org/#/c/9800/

A tool which helps to get list of modified files or list of all files in
GlusterFS Volume using Changelog or find command.

Usage
=====
glusterfind --help

Create:
-------
glusterfind create --help

The tool creates status file $GLUSTERD_WORKDIR/SESSION/VOLUME/status
and records current timestamp to initiate the session. This timestamp
will be used as start time for next runs.

As part of create also generates ssh key and distributes to all peers.
and enables build.pgfid and changelog using volume set command.

Pre:
----
glusterfind pre --help

This command is used to generate the list of files modified after session
creation time or after last run. To get list of all files/dirs in Volume,
run pre command with `--full` argument.

The tool gets all nodes details using gluster volume info and runs node
agent for each brick in respective nodes via ssh command. Once these node
agents generate the output file, tool copies to local using scp. Merges all
the output files to generate the final output file.

Post:
-----
glusterfind post --help

After consuming the list, this sub command is called to update the session
time based on pre command status file.

List:
-----
glusterfind list --help

To view all the sessions

Delete:
-------
glusterfind delete --help

Delete session.

Known Issues
------------
1. Deleted files will not get listed, since we can't convert GFID to
   Path if file/dir is deleted.
2. Only new name will get listed if Renamed.
3. All hardlinks will get listed.

geo-rep: mountbroker user management

2015-03-17T11:56:24+00:00

Non root geo-replication setup is now simplified. This
patch provides cli for mountbroker user and options management

To set Options,
    gluster system:: execute mountbroker opt  
    # for example,
    gluster system:: execute mountbroker opt mountbroker-root /var/mountbroker-root
    gluster system:: execute mountbroker opt geo-replication-log-group geogroup
    gluster system:: execute mountbroker opt rpc-auth-allow-insecure on

To remove option,
    gluster system:: execute mountbroker optdel 
    # for example,
    gluster system:: execute mountbroker optdel geo-replication-log-group

To add/edit user,
    gluster system:: execute mountbroker user  
    # for example
    gluster system:: execute mountbroker user geoaccount slavevol1,slavevol2

To remove user,
    gluster system:: execute mountbroker userdel 
    # for example
    gluster system:: execute mountbroker userdel geoaccount

For info,
    gluster system:: execute mountbroker info
    gluster system:: execute mountbroker -j info

For JSON output add -j after mountbroker, for example,
    gluster system:: execute mountbroker -j user geoaccount slavevol1,slavevol2

PS: Each peer prints its own JSON output, aggregator required from consumer side

geo-rep: Avoid duplicate entries in authorized_keys file

2015-03-06T02:27:40+00:00

When Georep create(force) command is run multiple times
it appends master nodes public keys to Slave nodes without
checking the existence of the key.

With this patch, create push-pem force adds pub key only if
not available in authorized_keys.

geo-rep: Add support for non standard AuthorizedKeysFile location

2015-02-20T02:56:28+00:00

In /etc/ssh/sshd_config, AuthorizedKeysFile can be customized
using %u and %h variables, %u will be replaced by user name
and %h will be replaced by home dir name. Default location is
.ssh/authorized_keys

For example,
AuthorizedKeysFile .ssh/authorized_keys
AuthorizedKeysFile %h/.my_secret_dir/authorized_keys
AuthorizedKeysFile /etc/ssh/keys/%u/authorized_keys

PS: Support only added for %h and %u in sshd_config

geo-rep: Handle copying of common_secret.pem.pub to slave correctly.

2015-01-22T06:58:41+00:00

Current Behaviour:
    1. Geo-replication gsec_create creates common_secret.pem.pub file
       containing public keys of the all the nodes of master cluster
       in the location /var/lib/glusterd/
    2. Geo-replication create push-pem copies the common_secret.pem.pub
       to the same location on all the slave nodes with same name.

Problem:
    Wrong public keys might get copied on to slave nodes in multiple
    geo-replication sessions simultaneosly.

     E.g.
      A geo-rep session is established between Node1(vol1:Master) to
      Node2 (vol2:Slave). And one more geo-rep session where
      Node2 (vol3) becomes master to Node3 (vol4) as below.

      Session1: Node1 (vol1) ---> Node2 (vol2)
      Session2: Node2 (vol3) ---> Node3 (vol4)

      If steps followed to create both geo-replication session is as
      follows, wrong public keys are copied on to Node3 from Node2.

      1. gsec_create is done on Node1 (vol1) -Session1
      2. gsec_create is done on Node2 (vol3) -Session2
      3. create push-pem is done Node1 - Session1.
          -This overwrites common_secret.pem.pub in Node2
           created by gsec_create in second step.
      4. create push-pem on Node2 (vol3) copies overwrited
         common_secret.pem.pub keys to Node3. -Session2

Consequence:
      Session2 fails to start with Permission denied because of wrong
      public keys

Solution:
      On geo-rep create push-pem, don't copy common_secret.pem.pub
      file with same name on to all slave nodes. Prefix master and
      slave volume names to the filename.

NOTE: This brings change in manual steps to be followed to setup
      non-root geo-replication (mountbroker). To copy ssh public
      keys, extra two arguments needs to be followed.

      set_geo_rep_pem_keys.sh   \
      
      
      Path to set_geo_rep_pem_keys.sh:
      Source Installation: 
              /usr/local/libexec/glusterfs/set_geo_rep_pem_keys.sh
      Rpm Installatino: 
              /usr/libexec/glusterfs/set_geo_rep_pem_keys.sh

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.

build: make GLUSTERD_WORKDIR rely on localstatedir

2014-08-07T08:17:29+00:00

- Break-way from '/var/lib/glusterd' hard-coded previously,
  instead rely on 'configure' value from 'localstatedir'
- Provide 's/lib/db' as default working directory for gluster
  management daemon for BSD and Darwin based installations
- loff_t is really off_t on Darwin
- fix-off the warnings generated by clang on FreeBSD/Darwin
- Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all
  platforms.
- Define proper environment for running tests, define correct PATH
  and LD_LIBRARY_PATH when running tests, so that the desired version
  of glusterfs is used, regardless where it is installed.
  (Thanks to manu@netbsd.org for this additional work)
