Here's a couple more Slackware RAID1 tidbits: I'm building another RAID1 array right now on Slackware 9.1 using the "Lange Method" :-) 1. I omitted "chunk-size" from /etc/raidtab, and got an error message. I had to add it before I could proceed. I suppose that answers my own "is chnk-size really necessary for RAID1" question. I went for size=4. 2. I am trying to create 5 devices (/dev/md0 to /dev/md4). The /dev/ directory (the one on the install CD I suppose it must be) only has 4 md devices (0 to 3). I tried creating an extra /dev/md4, but couldn't make it happen. An installed system has 16 possible md devices.
