Thanks all to provide the useful information.
Let me give some more background
There are two physical servers which are tie to a SAN disk. One server is active[A] and the other is standby[B].At any given time, only active server has mount to the san disk which means access to /app/logs/error.log
If active server has problem, then it will failover to standby server and that server become active and will have access to /app/logs/error.log
The idea is
1) if server A is active, and app is generating the logs in error.log, then copy that into server A /var/error.log. so lets say if there are three errors 1,2,3, then it should copy those three into var/error.log on server A
2) if server B is active, and app is generating the logs in error.log, then copy that into server B /var/errorl.log. so lets say if there are new errors 4,5,6, then it should copy those new errors into var/error.log on server B.
The error.log file never rollback / truncated. it just keep growing.
Not sure how to handle this situation. if the error.log file is too big and someone decided to archive and empty the file.
i think we need some well structured shell script
