Problems with rsync between NAS mounted filesystems

[Ed Coates]

Hi All,

Here is my setup.  I've to two NAS filesystems mounted on a SunFire  
V490.  They're mounted on /rsync/ieeprodhome/ECF and  
/rsync/ieeprodhome2/ECF.  The ieeprodhome filesystem is 1.008 TB wiht  
812GB used and the ieeprodhome2 filesystem is 1.2TB with 813GB used.   
One other thing to add that might be of importance is that the source  
filesystem has over 100k files in it.

Here is the command that I'm trying to use:

/opt/csw/bin/rsync -avvvv --delete /rsync/ieeprodhome/ECF/  
/rsync/ieeprodhome2/ECF

This will seem to run just fine for a couple of days, but then it will  
error out with the following:

rsync: connection unexpectedly closed (338935497 bytes received so  
far) [sender]

io.c(600) [sender=3.0.6]
_exit_cleanup(code=12, file=io.c, line=600): about to call exit(12)

Any clues on why it might be losing connection?  I don't have rsync  
running in daemon mode, so what would it be losing a connection to?
