Well, the reason we have our systems set to swap on RAID (we use RAID-1) is
that this improves our robustness. Even if one of our disks dies then the
swap continues to work and the system is still stable. Also, I believe, it
is possible to use a RAID-10 to stripe and mirror and actually improve
Hi all,
Is there an easy way to copy the partition information from one disk to
another disk that is exactly the same size? I'm guessing a dd on the right
device might do this but the exact command would be appreciated.
My goal is to not have to manually fdisk multiple disks
Hi all,
I think my situation is the same as this "two failed disks" one but I
haven't been following the thread carefully and I just want to double check.
I have a mirrored RAID-1 setup between 2 disks with no spare disks.
Inadvertantly the machine got powered down without a

Whether or not the array is in sync should not make a difference to the
boot process. I have both raid1 and raid 5 systems that run root raid and
will boot qu
Hi all,
I'm trying to add mirroring RAID to an existing partition. Is this possible?
It appears to me that when I do mkraid I'm going to kill the existing data.
Is there no way to tell it to use my exisiting data in a new RAID seting and
sync it to the new partition(s)?
Thank,

Speaking of IDE, can anyone answer me this. How come, when I use my IDE
drive heavily (like cat /dev/zero somefile) my system virtually freezes
up. This includes mouse, keyboard, everything. Eventually it comes back when
the disk IO is done but in the interim nothing moves. And, yes, I do have
Hi all,
I'm back and looking for more advice.
Ok, so I got my SCSI stuff running, seemingly smoothly, and decided to try
out RAID again. I started up md0 with 4 drives and 1 spare (actually the
spare was just another partition on one of the base 4 drives but what the
heck). I
Hi all,
I'm trying to do 2 things with SCSI/RAID both of which are having
problems. Any help would be greatly appreciated. My system is 2.2.14 with
the 5.1.22 Adaptec AIC-7xxx drivers.
First, I'm trying to get 4 SCSI drives working. Forget RAID, forget
anything complex, I just want
