Specifically, I’m thinking about the new

When I move a hard drive from one controller to another, I want the operating system to recognize it by the data on the drive, rather than by the cable its attached to. mount command, and of /etc/fstab. If I need to reorganize a system, and /dev/hda3 suddenly becomes /dev/hde3, I shouldn’t have to muck with /etc/fstab to get it right. Why? Because it seems like the only time I edit /etc/fstab is under times of duress. Something’s down, something’s wrong, you’ve just booted off the rescue disk, you have a only have minimalist editor (e.g. /bin/ae) handy, and you find yourself doing emergency repairs to /etc/fstab. You should be able to ask a disk partition « what are you? », and have the disk partition reply, and have the mount command respond to that.

To tackle the fresh guessing game away from just what information is on which controller sucks

Their even worse when you’ve reflected your resources partition. In these instances, you commonly find yourself handling singular exemplory instance of brand new echo, rather then everything. There’s a variety complicated grounds about how one to gets wedged in such a situation, however, it’s just not strange. Anyway, in this instance, you have a couple (or more?) copies away from /etc/fstab in the play. Which will get used becomes a function of new bootloader, new rescue diskette, the arbitrary BIOS push numberings strategy, and driver misunderstandings. Into a restart, the newest /etc/fstab that will get used may or may not end up being the one to you merely had over modifying.

Ext2fs labels. Their high that you can put a tag for the ext2fs with the new e2label demand. But are you aware that if one makes a RAID-1 mirror /dev/md1 of /dev/hda1 and you can /dev/hdc1, and set a keen Ext2fs label with it, that every about three of them gizmos are certain to get the exact same ext2fs term? Names are required from the cut-off-tool level, in addition to label needs to accept the true shops media becoming branded. The fresh new attach order, and you may /etc/fstab have to take cut-off-device brands, perhaps not document-system names.

The current Linux md subsystem spends ‘raid superblocks’ to save an effective UUID and you can cache other details. But there are no equipment that really enables you to research at that information, nor to place a label within. Never notice that you need to have the partition types of to get 0xfd rather than 0x83, and you will yada yada yada.

Possibly MSDOS-compatible hard drive partition dining tables is wrong? Possibly one of the most other partition table styles is best? If I’m not powering MSDOS otherwise Windows toward server, I don’t have to take the fresh new MSDOS partition dining table. Where’s the HOWTO that covers posts at this level? How do we rating tools to use these things?

File-program labels was fascinating, but they are not a complete address

The brand new LILO (version twenty-five.5.step three.1) has gone nuts. My history particular LILO don’t grumble one both of my hard drives were within 0x80. Now it does. Today I need to tell the clearly, that push step 1 try 0x80 and you can drive dos was 0x81. What’s step 1 and you will 2? I dunno. How much does 0x80 and you may 0x81 signify? We dunno, a wild & happy assume. And you will, regarding the maintaining the latest traditions regarding hosts doing what you told these to manage, instead of everything wished these to perform, LILO is starting to become most, really ready undertaking a footwear markets which is unbootable. This is exactly entirely unsuitable.

My personal options partition is reflected. I have a duplicate from / into the one another /dev/hda1 as well as on /dev/hdc1. Whenever i give LILO which i want a boot sector installed into the /dev/hda as well as on /dev/hdc, and to mount sometimes /dev/hda1 otherwise /dev/hdc1 since the sources partition, that’s what I’d like. Really don’t wanted which L 40 forty forty crap. I really don’t want LI 80 80 80 both. I don’t are interested providing confused about which is actually /dev/hda and you can that is /dev/hdc. We particularly don’t want they discovering yet another viewpoint on what are and therefore, versus my personal conserve diskette.
