Please forgive my ignorance. I'll provide any info required. Here's my situation. 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 exist: 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] 3 disks 4 partitions 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. _______________________________________________ Ataraid-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ataraid-list
