Hi, Could anyone tell me if an md device can be partitioned. when I do an fdisk on it it gives me a message telling me that md ioctl is obsolete, install new software and use new ioctl. i am currently using raidtools-0.90 the kernel patch I am using is raid0145-19990724-2.2.10 Thank you

I've got a dual proc SS20 that I'm using at my toy here. I'm running tiobench/tiotest on this machine to test out the raw performance of these disks, but I was sort of wondering what that (CPU%) number means on an SMP machine. Does it represent XX% of the total CPU cycles available are being use

I am trying to figure out what the best way to use paging space is with SW RAID. Should you avoid swapping altogether? Advantages: a) increased performance since you're not swapping (provided you've got enough physical memory) b) decreased risk of filesystem corruption on the RAID array in case
