There is no need to create the swap partitions as RAID drives. The simple solution is to use the ionice command to set the I/O priority of all swap partitions to the same value. The kernel then treats them in a manner similar to RAID 0. For performance reasons, you don't want anything to slow down swap.
And what will happen, should a drive containing swap fail, while the system is running? Would you recommend that to someone when uptime is critical?
If uptime were absolutely critical, I wouldn't be using Linux or any standard Unix for that matter. I would be have those apps running on QNX or a Stratus server.
QNX is the only OS certified for "life and death" equipment, such as hospital monitoring machines.
Regardless of the OS, the question remains the same. If you had a critical system, would you have swap on a non RAID drive? BTW, according to what I've read in several articles, Linux is being used in many critical applications. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
