RAID-0 swap is not the thing to run if reliability is a must, clearly. Interestingly, after a long fight with poor RAID-5 write speed, I moved my swap to RAID-10, only to find that recovery disks don't know how to use it. Tried Fedora and then a live CD (puppy, I think).
Detail on the RAID-5 performance thing in the linux-raid archives, won't rehash here. -- bill davidsen <davidsen@tmr.com> CTO TMR Associates, Inc Doing interesting things with small computers since 1979 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
