Please forgive my ignorance. I'll provide any info required. Here's my
I've been running a windows box with a promise fastrak controller. It's
got two disks in a striped configuration.
I recently installed an indepented 3rd disk, used it to install FC3, and
set up dmraid. dmraid recognized my raid and the entries in /dev/mapper
crw------- 1 root root 10, 63 Apr 29 00:19 control
brw-r----- 1 root root 253, 0 May 18 12:41 pdc_djbcgacc
brw-r----- 1 root root 253, 1 May 18 12:41 pdc_djbcgacc1
brw-r----- 1 root root 253, 2 May 18 12:41 pdc_djbcgacc5
The total disk space on the raid is 120 GB. I haven't allocated it all.
I want to use the unused space to create a linux "partition". This is
where I start to flounder. I don't have any experience configuring
software raid on Linux.
It seems like I should use LVM2 somehow except that I'm not sure how to do
so without destroying what I've already got on the disks. Here's the
output of lvmdiskscan:
/dev/hda [ 3.74 GB]
/dev/hde [ 57.25 GB]
/dev/hdg [ 57.25 GB]
/dev/hda1 [ 2.73 GB]
/dev/hde1 [ 4.89 GB]
/dev/hda2 [ 1019.75 MB]
/dev/hde2 [ 1.00 KB]
0 LVM physical volume whole disks
0 LVM physical volumes
What's my next step here? Please talk to me like I am 3 years old.
Thanks in advance.
