[Gluster-users] Geo-Replication faulty - Changelog register failed error=[Errno 21] Is a directory
Hello - I am having a problem with geo-replication on glusterv5 that I hope
someone can help me with.
I have a 7-server distribute cluster as the primary volume, and a 2 server
distribute cluster as the secondary volume. Both are running the same
version of gluster on CentOS 7: glusterfs-5.3-2.el7.x86_64
I was able to setup the replication keys, user, groups, etc and establish
the session, but it goes faulty quickly after initializing.
I ran into the missing libgfchangelog.so error and fixed with a symlink:
[root at pcic-backup01 ~]# ln -s /usr/lib64/libgfchangelog.so.0
/usr/lib64/libgfchangelog.so
[root at pcic-backup01 ~]# ls -lh /usr/lib64/libgfchangelog.so*
lrwxrwxrwx. 1 root root 30 May 16 13:16 /usr/lib64/libgfchangelog.so ->
/usr/lib64/libgfchangelog.so.0
lrwxrwxrwx. 1 root root 23 May 16 08:58 /usr/lib64/libgfchangelog.so.0 ->
libgfchangelog.so.0.0.1
-rwxr-xr-x. 1 root root 62K Feb 25 04:02 /usr/lib64/libgfchangelog.so.0.0.1
But right now, when trying to start replication it goes faulty:
[root at gluster01 ~]# gluster volume geo-replication storage
geoaccount at 10.0.231.81::pcic-backup start
Starting geo-replication session between storage &
geoaccount at 10.0.231.81::pcic-backup
