It is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions. Now, many admins (both Windows and Linux/UNIX) follow an old rule of thumb that your swap partition should be twice the size of your main system RAM. Let us say I've 32GB RAM, should I set swap space to 64 GB? Is 64 GB of swap space really required? How big should your Linux / UNIX swap space be? ]]> http://www.cyberciti.biz/tips/linux-swap-space.html/feed 52 Record Labels To Sue SourceForge Open Source Project Hosting Platform http://www.cyberciti.biz/tips/record-labels-sue-vuze-limewire-sourceforge.html http://www.cyberciti.biz/tips/record-labels-sue-vuze-limewire-sourceforge.html#comments Sun, 16 Nov 2008 08:35:05 +0000 Vivek Gite http://www.cyberciti.biz/tips/?p=3548 Consider this ... the stupidest example of law.

How can I test if my hard disk is going bad? I see few errors in /var/log/messages file.
I/O errors in /var/log/messages indicates that something is wrong with the hard disk and it may be failing.
