Hi,
I wrote a rsync script to backup my laptop data on my desktop. The script tries to mount a directory from the desktop, checks that is is properly mounted and starts rsync to backup my laptop home directory on the desktop.
This worked fine when I tested it on small amount of data. But as soon as I run it to backup a bigger directory, rsync will hang after around 60Mb of data uploaded.
dmesg reports nfs timeout on the laptop. From that point onwards, the network does not work anymore. A new nfs timeout comes in dmesg every 20 seconds. No ping, no web surfing. I can still disconnect and reconnect using network manager, this will report proper connection, but in reality no connection works.
I eventually had a full system hang when rebooting...
I googled and found few similar cases, people telling this could be related to some specific network cards not managing "big ammount of data", but no clear solution found so far.
I changed mount option for the NFS directory to "soft" and icreased timeo from 14 to 24. No idea if that could be the right idea, but in all cases it didn't work so far...
Any suggestions ?
