Today I had a name-server stop resolving DNS due to the /var directory being full from the named.run cache build up. I tried removing all the files using:
rm -rf name*
However, although running ls showed now files in the directory "data" running df -h still showed 100% use on /var. In the end I rebooted the machine and this resolved the problem but I am a little confused why this did not delete the files. (Obviously rebooting is not something I want to do every time even though we have failover.) Does anyone know the reason?
