Subject: mkraid creating 5G raid device from 110G partitions
Date: Fri, 05 Dec 2003 17:38:42 -0800 [thread overview]
Message-ID: <3FD13322.4060906@hosttuls.com> (raw)
Hello all,
I'm trying to create a RAID-1 array using 2 WD hard drives on a
server running knoppix. For some reason mkraid /dev/md1 creates a raid
device that is only 5 Gigs, however the partitions I am using in the
array are about 110Gigs. This is urgent, so if the answer to this is
out there but I havent found it on google yet, I apologize.
Here is the relevant Raid configuration:
The server is running knoppix 3.3, 2 WD 120Gig HD's, 2G Ram
mkraid version 0.90.0
root@0[mnt]# fdisk -l
Disk /dev/hda: 120.0 GB, 120034123776 bytes
