Re: Upgrade to 4.1.1 geo-replication does not work

[Kotresh Hiremath Ravishankar <khiremat@xxxxxxxxxx>]

Hi Marcus,

Well there is nothing wrong in setting up a symlink for gluster binary location, but

there is a geo-rep command to set it so that gsyncd will search there.

To set on master
#gluster vol geo-rep <mastervol> <slave-vol> config gluster-command-dir <gluster-binary-location>

To set on slave
#gluster vol geo-rep <mastervol> <slave-vol> config slave-gluster-command-dir <gluster-binary-location>

Thanks,

Kotresh HR

Hi Marcus,

I am testing out 4.1 myself and I will have some update today.

For this particular traceback, gsyncd is not able to find the library.

Is it the rpm install? If so, gluster libraries would be in /usr/lib.

Please run the cmd below.

#ldconfig /usr/lib

#ldconfig -p /usr/lib | grep libgf  (This should list libgfchangelog.so)

Geo-rep should be fixed automatically.

Thanks,

Kotresh HR

Hi again,

I continue to do some testing, but now I have come to a stage where I need help.

gsyncd.log was complaining about that /usr/local/sbin/gluster was missing so I made a link.

After that /usr/local/sbin/glusterfs was missing so I made a link there as well.

Both links were done on all slave nodes.

Now I have a new error that I can not resolve myself.

It can not open libgfchangelog.so

Many thanks!

Ämne: Re: Upgrade to 4.1.1 geo-replication does not work

 

Hi Kotresh,

I have been testing for a bit and as you can see from the logs I sent before permission is denied for geouser on slave node on file:

/var/log/glusterfs/cli.log

I have turned selinux off and just for testing I changed permissions on /var/log/glusterfs/cli.log so geouser can access it.

Starting geo-replication after that gives response successful but all nodes get status Faulty.

If I run: gluster-mountbroker status

I get:

+-----------------------------+-------------+---------------------------+--------------+--------------------------+
|             NODE            | NODE STATUS |         MOUNT ROOT        |    GROUP     |          USERS           |
+-----------------------------+-------------+---------------------------+--------------+--------------------------+
| urd-gds-geo-001.hgen.slu.se |          UP | /var/mountbroker-root(OK) | geogroup(OK) | geouser(urd-gds-volume)  |
|       urd-gds-geo-002       |          UP | /var/mountbroker-root(OK) | geogroup(OK) | geouser(urd-gds-volume)  |
|          localhost          |          UP | /var/mountbroker-root(OK) | geogroup(OK) | geouser(urd-gds-volume)  |
+-----------------------------+-------------+---------------------------+--------------+--------------------------+

and that is all nodes on slave cluster, so mountbroker seems ok.

gsyncd.log logs an error about /usr/local/sbin/gluster is missing.

That is correct cos gluster is in /sbin/gluster and /urs/sbin/gluster

Another error is that SSH between master and slave is broken,

but now when I have changed permission on /var/log/glusterfs/cli.log I can run:

ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no -i /var/lib/glusterd/geo-replication/secret.pem -p 22 geouser@urd-gds-geo-001 gluster --xml --remote-host=localhost volume info urd-gds-volume

as geouser and that works, which means that the ssh connection works.

Is the permissions on /var/log/glusterfs/cli.log changed when geo-replication is setup?

Is gluster supposed to be in /usr/local/sbin/gluster?

Do I have any options or should I remove current geo-replication and create a new?

How much do I need to clean up before creating a new geo-replication?

In that case can I pause geo-replication, mount slave cluster on master cluster and run rsync , just to speed up transfer of files?

Many thanks in advance!

Hi Kotresh,

Yes, all nodes have the same version 4.1.1 both master and slave.

All glusterd are crashing on the master side.

Will send logs tonight.      

Thanks,

Marcus

Is the gluster geo-rep version is same on both master and slave?

Hi Kotresh,

i have replaced both files (gsyncdconfig.py and repce.py) in all nodes both master and slave.

I rebooted all servers but geo-replication status is still Stopped.

I tried to start geo-replication with response Successful but status still show Stopped on all nodes.

Nothing has been written to geo-replication logs since I sent the tail of the log.

So I do not know what info to provide?

Please, help me to find a way to solve this.

Thanks!

Thanks Kotresh,

I installed through the official centos channel, centos-release-gluster41.

Isn't this fix included in centos install?

I will have a look, test it tonight and come back to you!

Thanks a lot!

I think the fix [1] is needed in 4.1

Could you please this out and let us know if that works for you?

Hi all,

I have upgraded from 3.12.9 to 4.1.1 and been following upgrade instructions for offline upgrade.

I upgraded geo-replication side first 1 x (2+1) and the master side after that 2 x (2+1).

Both clusters works the way they should on their own.

After upgrade on master side status for all geo-replication nodes is Stopped.

I tried to start the geo-replication from master node and response back was started successfully.

Status again .... Stopped

Tried to start again and get response started successfully, after that all glusterd crashed on all master nodes.

After a restart of all glusterd the master cluster was up again.

Status for geo-replication is still Stopped and every try to start it after this gives the response successful but still status Stopped.

Please help me get the geo-replication up and running again.

Best regards

Marcus Pedersén
