2010-05-30 Thread Gregory Pavelcak
Hi, I've been messing around with setting up a Ken's file server with old hardware that's accumulated over the years. Yesterday, I configured a file server with two IDE drives as ch0fh2. The setup seemed to go OK, but one of the last things on the screen before it brought the server up is in the

[9fans] PCI SATA Controller Cards

2010-05-30 Thread Gregory Pavelcak
On a file-server related note, I almost feel committed to SCSI drives because I have a nice Tekram controller. However all of my drives are so old that I'm suspicious of them and buying new SCSI is expensive. It looks like I could switch to SATA controller and drives for less money than a couple

Thanks Erik. Yeah, the "f" device is just a consistent brain tic for me. Once upon a time I thought for some reason that "f" always went with "c" unless you were using a real jukebox, and now I can't seem to get rid of that misapprehension when I write my configs. I used "h2" because I intended t
