morning,
I have a software Raid 1 setup with 2 disks.
/dev/hdc1
/dev/hdd1
I've noticed that preformance has slowed a bit since the raid setup.
I also have both disks on the same controller.
Would it make a difference if the disks were on seperate controllers?
ex.
Move /dev/hdd1 to /dev/hda1, the
Thank ya Alvin for all the help. By what youi wrote the first time I was
not clear on wether or not you knew I did not have a hardware controller.
But the built in kernel raid is what I was talking about. Thanks for the
additional info it will help a lot.

Hi,
Thanks for the info. But my issue is that I do not have a RAID Controller.
I was looking at

Thanks

Is it possible with the newer kernels to actually boot to a software
raid?? I have a machine with 4 SCSI drives and I want to be able to RAID
1 the drives in pairs. One pair for the / and the second pair for /var
only. But everything I have read to date says you cannot do this.
