Environment: Dell XPS 400, which uses Intel 82801GR (ICH7) I/O controller with RAID RAID set has 2 drives configured for mirroring System and swap are on the RAID set Problem: When the system is booted after installing the system, the mirroring did not get activated. This can be seen in the disk write counts shown by vmstat -d. Almost all the writes are on one drive; with mirroring the counts should be about the same for both drives. How reproducible: Every time Steps to Reproduce: 1. Clear disk 2. Install system 3. Boot installed system Actual results: Almost all the disk reads and writes are on one drive Expected results: Disk writes should be about the same on both drives. I would expect reads to be split across the drives, but they don't have to be.

It looks like the source of the problem is the + in the raid group name. Here is the output from dmsetup: [root@localhost fedora]# dmsetup table isw_dgjddddaee_Drives0+13: 0 20482875 linear 253:1 290824695 isw_dgjddddaee_Drives0+1: 0 312494080 mirror core 2 131072 nosync 2 8:0 0 8:16 0 isw_dgjddddaee_Drives0+12: 0 249858945 linear 253:1 40965750 isw_dgjddddaee_Drives0+11: 0 40965687 linear 253:1 63 live-rw: 0 8388608 snapshot 7:121 7:119 P 8 The + causes problems in resolve_dm_name (in /etc/init.d/functions) when the name is used as a pattern in awk. The + is interpreted by awk as meaning "match one or more of the preceeding character", not match itself.

I changed the name of the raid group to remove the +. That made it work.
