I have a server running on linode. The server is a headless Ubuntu 10.0.4 64 bit installation.
I have recently started getting high disk I/O alerts from the server. As far as I know, nothing much has changed on the server.
Is there a *nix utility that I can run on the server to either monitoring and log, or perhaps analyze an existing log in order to find out which process(es) are "trashing" the disk?
