[Gluster-users] GeoRep Faulty after Gluster 7 to 8 upgrade - gfchangelog: wrong result

Thu Mar 18 22:22:37 UTC 2021

Sadly,
I'm out of ideas. It makes sense... if the changelog was changed - then it won't work after the upgrade.
I guess that once you delete the session, you can remove the extended attribute for the time.

 But I did notice that the changelog format had changed, instead of them being dumped into one directory, they now seem to be separated in year/month/day directories... 

 Looks like this change in 8.0: https://github.com/gluster/glusterfs/issues/154

 And there seems to be an xattr for time in the brick root - presumably for when changelogs were enabled: 

 [root at storage01 changelogs]# getfattr -d -m. -e hex /data/storage_a/storage 2>&1 | egrep xtime
trusted.glusterfs.cf94a8f2-324b-40b3-bf72-c3766100ea99.xtime=0x60510140000ef317

 Reading through the changes, it looks like there is a script to convert from one format to the other... I didn't see anything in the release notes for 8.0 about it... this seems like it could be the fix, and explain why gluster can't get through the changelogs....  Thoughts?

 Have you verified all steps for creating the geo-replication ? 
  If yes , maybe using "reset-sync-time + delete + create" makes sense.Keep in mind that it will take a long time once the geo-rep is established again.

 I wanted to make sure the issue wasn't occurring because there were no new changes to sync from the master volume. So I created some files and restarted the sync, but it had no effect.

 So, then if I'm going to have to resync, what is the best way to do this? 

 With delete or delete reset-sync-time ?   https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/sect-starting_geo-replication#Deleting_a_Geo-replication_Session

 Erasing the index? So I don't have to transfer the files again that are already on the backup? 

   - https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.1/html/administration_guide/sect-troubleshooting_geo-replication#Synchronization_Is_Not_Complete 
   - https://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Administrator%20Guide/Geo%20Replication/#best-practices   

 Is it possible to use the special-sync-mode  option from here: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/sect-disaster_recovery

 Thoughts? 

 Thanks,

 Usually, when I'm stuck - I just start over. For example, check the prerequisites: - Is ssh available (no firewall blocking) - Is time sync enabled (ntp/chrony) - Is DNS ok on all hosts (including PTR records) - Is the gluster version the same on all nodes (primary & secondary) 
  Then start over as if the geo rep was never existing. For example , stop it and start over with the secondary nodes's checks (mountbroker, user, group) . 
  Most probably somwthing will come up and you will fix it. 
  In worst case scenario, you will need to clean ip the geo-rep and start fresh.

 Yes, SELinux was put into permissive mode on the secondary nodes as well: 

 [root at pcic-backup01 ~]# sestatus | egrep -i  "^SELinux status|mode"
 SELinux status:                 enabled
 Current mode:                   permissive
 Mode from config file:          enforcing

 [root at pcic-backup02 ~]# sestatus | egrep -i  "^SELinux status|mode"
 SELinux status:                 enabled
 Current mode:                   permissive
 Mode from config file:          enforcing

 The secondary server logs didn't show anything interesting:

 I'm really at a loss for where to go from here, it seems like everything is set up correctly, and it has been working well through the 7.x minor versions, but the jump to 8 has broken something...

 There definitely are lots of changelogs on the servers that fit into the timeframe..... I haven't made any writes to the source volume.... do you think that's the problem? That it needs some new changelog info to sync? 
 I had been holding off making any writes in case I needed to go back to Gluster7.9 - not sure if that's really a good option or not.

 It looks like perhaps the changelog_log_level and log_level options? I've set them to debug: 

 [root at storage01 ~]# gluster volume geo-replication storage geoaccount at 10.0.231.81::pcic-backup config | egrep -i "log_level"

 [root at storage01 ~]# gluster volume geo-replication storage geoaccount at 10.0.231.81::pcic-backup config log_level DEBUG

 Then I restarted geo-replication:

I think you have to increase the debug logs for geo-rep session.
I will try to find the command necessary to increase it.

Thanks Strahil,

Right - I had come across your message in early January that v8 from the CentOS Sig was missing the SELinux rules, and had put SELinux into permissive mode after the upgrade when I saw denied messages in the audit logs.

[root at storage01 ~]# sestatus | egrep "^SELinux status|[mM]ode"
SELinux status:                 enabled
Current mode:                   permissive
Mode from config file:          enforcing

Yes - I am using an unprivileged user for georep:

[root at pcic-backup01 ~]# gluster-mountbroker status

I have tested georep on v8.3 and it was running quite well untill you involve SELINUX.

Are you using SELINUX ?

Are you using unprivileged user for the georep ?

Also, you can check https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.4/html/administration_guide/sect-troubleshooting_geo-replication .

Hello,

I recently upgraded my Distributed-Replicate cluster from Gluster 7.9 to 8.3 on CentOS7 using the CentOS Storage SIG packages. I had geo-replication syncing properly before the upgrade, but not it is not working after.

After I had upgraded both master and slave clusters I attempted to start geo-replication again, but it goes to faulty quickly:

I went through the gsyncd logs and see it attempts to go back through the changlogs - which would make sense - but fails:
