[Gluster-users] geo-replication not syncing files...

Hi all,
i need some help with a geo-replication issue...
recently i upgraded two 6-node distributed-replicated gluster from
ubuntu 12.04.5 lts to 14.04.3 lts resp. glusterfs 3.4.7 to 3.5.6
since then the geo-replication does not start syncing but remains as
shown in the 'status detail' output below for about 48h.
I followed the hints for upgrade with an existing geo-replication :
http://www.gluster.org/community/documentation/index.php/Upgrade_to_3.5
the master_gfid_file.txt was created and applied to the slave volume.
geo-replication was started with 'force' option.
in the gluster.log on the slave i can find thousands of lines with
messages like :
".../.gfid/1abb953b-aa9d-4fa3-9a72-415204057572 => -1 (Operation not
permitted)"
and no files are synced.
I'm not sure whats going on and since there are about 40TByte of data
already replicated by the old 3.4.7 setup I have some fear to try around...
so i got some questions...maybe somebody can give me some hints...
1. as shown in the example below the trusted.gfid of the same file
differs in master and slave volume. as far as i understood the
upgrade-howto after applying the master_gfid_file.txt on the slave they
should be the same on master and slave...is that right ?
2. as shown in the config below the change_detector is 'xsync'.
Somewhere i red that xsync is used for the initial replication and is
changing to 'change_log' later on when the entire sync is done. should i
try to modify the change_detector to 'change_log', does it make sense...?
any other idea which could help me to solve this problem....?
best regards
dietmar
