I have seen several methods to do this: Well, on a Red Hat system I have here, this works fine: #boot=/dev/sda default=0 timeout=10 #splashimage=(hd0,0)/grub/splash.xpm.gz title Red Hat Linux (2.4.9-34enterprise) root (hd0,0) kernel /vmlinuz-2.4.9-34enterprise ro root=/dev/md3 console=ttyS0,9600n8 initrd /initrd-2.4.9-34enterprise.img There are multiple RAID1 partitions on two disks, and grub is installed to /dev/sda. I don't believe grub is mirrored across disks, though. Since software RAID on Linux works partition-by-partition, and not on whole disks, I don't see how you could automatically mirror the MBR across disks. You could install grub to multiple MBR's, though, one for each disk. It wouldn't gain you anything unless your BIOS can boot from the other disks, though. -- Charles R.

[Fwd: Clarify: GRUB setup on RAID1]

by Brett Russ

Can anyone on this list shed some light on my question below? Thanks, Brett -------- Original Message -------- Subject: Clarify: GRUB setup on RAID1 Date: Tue, 19 Nov 2002 15:34:03 -0500 From: Brett Russ <icycle(a)charter.net> To: bug-grub(a)gnu.org I looked through all of the archives on this list as well as google searching for help. I want to make sure that GRUB supports installation on RAID1 (mirror) units. I have seen several methods to do this: Method 1) device (hd0) /dev/hde root (hd0,0) install /boot/grub/stage1 (hd0,0) /boot/grub/stage2 0x8000 (hd0,0)/boot/grub/menu.lst install /boot/grub/stage1 d (hd0) /boot/grub/stage2 0x8000 (hd0,0)/boot/grub/menu.lst device (hd0) /dev/hdg root (hd0,0) install /boot/grub/stage1 (hd0,0) /boot/grub/stage2 0x8000 (hd0,0)/boot/grub/menu.lst install /boot/grub/stage1 d (hd0) /boot/grub/stage2 0x8000 (hd0,0)/boot/grub/menu.lst ...and so on for each device--substituting each additional RAID1 member drive in the /dev/hdX line. Method 2) echo '(hd0) /dev/md0' > /boot/grub/device.map grub-install '(hd0)' ...and so on for each (hd#) that is part of the md. Method 3) root (hd0,0) setup (hd0) ...and so on for each hd# present in the RAID1. My question is whether the /dev/hdX syntax or /dev/md# or (hd#) syntax is correct and what the significance of the value 0x8000 for the Stage 2 load address. It certainly seems like method 3 is the cleanest. And, are any of these methods considered better than the others?

I've got an HP OfficeJet K60 that works quite nicely under SANE. I'm afraid the demo of installing would be a bit boring... printing worked out of the box with redhat 7.3, and scanning required installing 1 rpm. I've been playing with a CGI to make scanning a bit more streamlined (and something that I can do from work when I don't feel like working). It's still a work in progress, but I can show it off too. All this and we should still be able to hit the Boytan by 7:30. :) Scott

Hi Andy, I have, and can demo LTSP, as well as using sockets in a Linux/ Win4Lin environment to do distributed, Linux/Windows batch jobs (I have a batch job that runs perl under Linux (requires too much memory for win4lin) and three windows programs under win4lin in order to convert RTF to ThML). Rob Bellville has some Macs running LTSP at the Millbury HS, and said he'd be willing to host a WLUG meeting at the school so we could have a hands-on demo. Unfortunately, I have aconflict on Wednesdays, so can only make the Thursday meetings. Perhaps at a future date we can work something out. --Skip

I know, I know, I never come to the meetings; but I'll put in a couple of sugguestions.... How about a demo of one of the open-source pvr projects? If anyone has worked with one, that is... ***OR*** I wonder if a "patch-night" would be fun. Take a vanilla kernel, have everyone bring in their favorite patches; and people can build a custom super-kernel..... Need acpi? no problem. Need supermount? no problem (I'm a mandrake loser, sue me) Win4lin? Sure! Tpconfig? Got it right here! AMD Chip? we're compiling now Was that for PPC? Right this way.... And so on. The more I read kernel lists and such, the more I realize that I don't know half of the great kernel-patches out there; this might be a fun way to learn... Just an idea....

Well, I won't be able to make the meeting, but if you want to see a little hack I did to my TiVo (yes, it runs Linux on a PPC processor), you can look at my homepage: http://www.kluge.net/~felicity/ It tells you what my TiVo is currently watching, as well as the listing of what it will be recording (todo), what's available to watch (now showing), and programs we told it to record (season passes). All the programming is done in TCL. I use the tivoweb software, which is essentially a webserver that interfaces with the TiVo data. I wrote/hacked together a few modules that grabs the information from the TiVo and spits it out in an easily parsible format. My linux server then grabs periodically via cron that information and puts it on the web server. :) There are some other standard modules that let you control the TiVo via web browser, etc. I really just like the fact that it uses my home broadband connection to get the daily information instead of the usual dial-up via modem. ;) -- Randomly Generated Tagline: They can always run stderr through uniq. :-) -- Larry Wall in <199704012331.PAA16535(a)wall.org>
