Re: mkraid could not lock sda2
UPDATE on bottom
[snip]
_______________________________________________________
sda1 is a swap partition and im 100% sure that isnt being used (I have
2 gigs of ram hehe) sda2 is being used thats what I boot from ... but ..
what else can I do ? the error is on sda1 .. /etc/fstab =
below ..
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump>
<pass> /dev/sda2 / ext3 errors=remount-ro 0
1 /dev/sda1 none swap sw &
amp;
nbsp; 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto user,noauto 0 0
/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0
Your fstab shows that sda1 is being used, as swap. Remove that line from
your fstab when you boot, and also use a program such as fdisk to change
the partition type from Linux swap to Linux Raid Autodetect. If you're
going to try to boot from your raid array, mark the partition as bootable.

I booted from sda and thats where i running mkraid from. Do I need
to run it on a floppy or something? on boot I got this ..
It doesn't matter what physical disk you boot from, but you have to be sure
that you aren't using the partitions you want to use in your raid set for
anything else when you boot.

Thanks.
UPDATE : ok I did swapoff -a (turns the swap off and it let me
mirror the swap partition)
:0)
but now i try to do the
main partition sba2 and it says device is busy ..
I went into ini1 (I think thats one user mode) and it still did
it... heeelllpppppp
I thought your swap partition was sda1. I'm assuming you mean sda2 instead
of sba2 above, right? If so, that device is still busy, because it's your
root partition (at least, according to your fstab).
Concentrate on /dev/md0 for now. Make sure you aren't using /dev/sda1
and /dev/sdb1 for anything when you boot. Don't mount them, or anything.
Then, you should be able to make them into a raid device.
Post your results, and we'll go from there.

my swap partition is sda1. I have turned swap off and I have /dev/md0
= the mirrored swap ...... but I cant get the sda2 (all the data and
stuff) ...
so you say I just need to restart? I have tried that but ... it just
gives errors.. do I need to boot a special way?
