800xa SV 4.1 Aspect server 3 File set distribution service in synchronizing state
We are using 800xA SV 4.1 system having 2oo3 aspect servers. We are having always third aspect server service "File set distribution service " in synchronizing state not coming to service state. Restart server but still same situation any solution how to normalize,
Could be a corrupted database preventing synchronization.
Have you looked in the [Workplace Structure]Web System Workplace:System Event List for FSD related events?
I believe synchronization is made with the Service Provider listed first in the FSD Service Group. If AS3 can not sync with AS1 (normally being the first in group) try reordering the group so that AS2 becomes first.
Also, it is possible to force a full cold start by renaming the \OperateITData\FsdServer folder on the failing server and see if the slaving FSD provider can complete synchronization when starting from a clean slate. If this works (AS3 enter Service state after completing synchronization) you could then cold start FSD in AS1. In the end, the \OperateITData\FsdServer\data folder should be more or less equally sized on all three aspect servers.
In later versions of System 800xA, a problem with something called "Orphan Filesets" have been corrected or improved. Orphaned filesets can cause trouble for FSD if they became too many in numbers.
If you can't sort out the problems on your own, I suggest filing a support case with your regional ABB support center.
