I can't find any way around this. Looking at my /etc/raidtab file: raiddev /dev/md0 raid-level 1 nr-raid-disks 2 nr-spare-disks 0 persistent-superblock 1 device /dev/sdc1 raid-disk 0 device /dev/sdd1 raid-disk 1 raiddev /dev/md1 raid-level 0 nr-raid-...

A last step is missing; something like marking the arrays that they are clean. I see this happening for a flash of a second when...

Hello all, I've got CentOS 5.2 installed on an old Pentium III server. The server is used by a club at my school, and they are rapidly running out of room on the internal IDE drives that are configured in software RAID 1. I have a Silicon Image SATA controller in the server, and I was planning on adding two more SATA hard drives to the computer. Is there a GUI like Disk Druid for
