Hi all, My question has to do more with hardware than with software, but still applys to the list. We are doing raids with debian in my class, and now it's raid 1 on 2 hard drives. My knowledge of hardware almost equals zero. SO, on my linux box, how do I install 2 master hard drives w/o messing up the cd rom as well since there are only 2 IDE channels plus the floppy drive one? I need to set it up for excersising purposes. Many thanks in advance! Ned ^ permalink raw reply [flat|nested] 8+ messages in thread

I don't know if it's software or hardware, and I also haven't used software raid since the 2.4.x kernels. So, I stand to be corrected, but if you're setting up software raid under gnu/linux, partitioning the drives individually, with separate file systems, is not the way to do it, unless things have drastically change since I did it, which I doubt is the case.

* Re: raids ` raids Gregory Nowak @ ` Luke Davis ` raids Ned Granic 1 sibling, 0 replies; 8+ messages in thread From: Luke Davis @ UTC (permalink / raw) To: Speakup is a screen review system for Linux. Greg is correct on all counts. You have to create the MD devices from the "setup software RAID" option, prior to formatting anything. After you do this, you will have to create your new file systems (EXT3, etc.) on those MD devices, not on HDA or HDB. You are building layers. It seems as if you have tried to put layer 2 on top of layer 0, instead of layer 1 (RAID) on top of 0 (the raw partitions), and then 2 (the file systems) on top of 1 (RAID). Additionally, since you are trying to mount both file systems on slash, you may not realize that unix sees everything as one single file system. You have one, mounted at slash (the root FS), and others mounted at various mount points thereunder. You should not think of software RAID as a file system which must be mounted, but as a partitioning layer gwhich must be created before you can mount anything. For example, if you have HDA1 and HDB3, of identical sizes, and you wanted to operate a RAID 1 device using those partitions, you would create a device called MD0, by using the RAID setup tools appropriate (or the installer if it supports it, which yours' seems to do). Then, instead of having HDA1 or HDB3 any more, you will have only MD0. You will make one file system, on MD0, and leave the HDA1 and HDB3 devices alone, as RAID's md0 is now handling them.

* Re: raids ` raids Gregory Nowak ` raids Luke Davis @ ` Ned Granic 1 sibling, 0 replies; 8+ messages in thread From: Ned Granic @ UTC (permalink / raw) To: Speakup is a screen review system for Linux. Thanks Greg for your promptness. Yes, I am, and in fact succeeded in setting up the software raid 1 in Debian/New 2.6. I messed up while matching the partitions and did not quite understand the error message; impatience or what. But now everything is clear. Yes, nothing has changed as far as partitioning each drive separately goes, but why with different file systems? I know nothing about hardware raids. Anyway, I dug my self out of the ditch and found out what was the problem; one needs to be careful when checking things with the space bar since speakup "read line" command will miss that asterisk in front of the designated line, so we need to verify it with the char-by-char navigation. And that thing is now working! Thanks for the site as well! Cheers!
