[S.u.S.E. Linux] Multiple drives with only 1 mount point
How do I install everything (all packages) onto three hard disks using one mount point ( / ). I have not been able to figure this out. Thanks, Otis Lamar CLUE Denver -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
There are good reasons to use multiple partitions. If however you choose to use only a single partition you will not be able to use all three drives. Linux sees each hard drive as a device, and subsequently each partition as a device as well. / could not exist across multiple devices to my knowledge, because each mount point can only occupy one device. Perhaps a better approach would be for you to use multiple partitions. A little more information on how large your hard drives are and whether this will be a single-user or multiple-user box and perhaps we can be more help. Otis Lamar wrote:

Hi Otis!! Look in the multi-disk how-to. It appears that you need to add partitions together using 'mdadd' then activate the partitions using 'mdrun'. I know that is oversimplified so you'll need to read. on my system, running suse5.2: file://localhost/usr/doc/howto/html/Multi-Disk-HOWTO-9.html several examples included :-) on the web: <A HREF="http://sunsite.unc.edu/LDP/HOWTO/Multi-Disk-HOWTO.html"><A HREF="http://sunsite.unc.edu/LDP/HOWTO/Multi-Disk-HOWTO.html</A">http://sunsite.unc.edu/LDP/HOWTO/Multi-Disk-HOWTO.html mc p.s. Let me know if that helps. Or, you can drag you box over to my place on the weekend and we can figure it out. -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
Otis, I was unaware of this. I didn't mean to mislead you with my earlier response, I simply didn't know that it was possible to have a single partition exist across multiple devices. My bad.

let me see: If you want to have *one* extremely big partition for everything (spanning all 3 HD's) then you'd need a raid controller (hardware). And I'd tell you this would be a very bad idea: if a log-file grows like mad it can lock up all the space you have, instead of only filling up /var (which is bad enough) and fscking takes a long time with such large partitions ... and fragmentation (though usually not a problem) might hit you, because you have short and long-life files on the same partition. In other words ... if you don't have a very compelling reason, don't. Use separate / /usr /home /tmp /var /var/spool/news /usr/src ... -Partitions. Or at least / /usr /home and /tmp ... Anyway you'll need 2 partitions at least ... you'll want swap partitions (I'd say 1 per HD, so the head movement is reduced). But: Linux --- like any Unix --- has no c: d: e:, maybe this is your misunderstanding ... it's like a tree: / /usr /home /var /tmp /user1 /user2/ /var/spool /var/spool/news and noone needs to know if /usr is on the same partition, or the same HD, or even on the same computer (if you use nfs or something like it). The kernel knows, and handles it completely transparently. So installing in such a system will work ... and if / is on HD1, /usr is on HD2 and /usr/src is on HD3, all files in /... that are not /usr/... go to HD1, all /usr/... but not /usr/src/... go to HD2 etc. Actually that means that you can move (e.g. with tar) a part of your files (all in or below a directory, e.g. /usr/src) on a different partition/disk/computer and just mount them to the old name (/usr/src) and nothing will break, because the path (e.g. /usr/src/linux/README) did not change --- you just have suddenly much more space in /usr and in /usr/src ...

Won't work (here), because you must activate the partitions by mdrun, which is on / --- thus / can't be multi-disked. Same with software-raid ... you need to start it, before you can use it, so it both will work for all partitions but /. -Wolfgang -- PGP 2 welcome: Mail me, subject "send PGP-key".
