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. install 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 new guessing game away from exactly what information is on which controller sucks
Their tough when you’ve reflected you root partition. In such cases, you tend to wind up dealing with one example of the latest echo, rather than the whole thing. Discover a selection challenging reasons on what that gets wedged such a posture, however, its not uncommon. Anyhow, in this instance, you have a couple (or maybe more?) copies from /etc/fstab into the play. Which one will get made use of becomes a purpose of the latest bootloader, new help save diskette, new arbitrary BIOS push numberings system, and you may user distress. Towards any given restart, the latest /etc/fstab that will get put may or may not end up being the one to you merely got complete editing.
Ext2fs brands. Their higher that one may place a tag with the ext2fs which have this new e2label order. However, are you aware that if you make an effective RAID-1 echo /dev/md1 off /dev/hda1 and you may /dev/hdc1, and place a keen Ext2fs identity inside, that around three of those gizmos are certain to get alike ext2fs title? Labels are needed within cut off-equipment peak, and the name must live with the actual sites media becoming labelled. The brand new mount demand, and you can /etc/fstab have to take stop-product labels, perhaps not file-program names.
The modern Linux md subsystem uses ‘raid superblocks’ to save a good UUID and you may cache almost every other information. But there aren’t any gadgets that truly allows you to look at this information, nor to http://datingranking.net/pl/gaydar-recenzja place a label in there. Never mind that you’ll require your own partition sorts of to get 0xfd and never 0x83, and you may yada yada yada.
Possibly MSDOS-compatible disk drive partition tables are incorrect? Maybe among most other partition desk looks is perfect? If the I’m not running MSDOS or Screen to the servers, I really don’t need to use brand new MSDOS partition dining table. Where’s the fresh new HOWTO one to talks about posts at this level? How can we score systems to use these things?
File-program brands is actually interesting, but they are not a whole address
The brand new LILO (variation 25.5.3.1) went wild. My history brand of LILO failed to complain that both of my personal hard disk drives was in fact on 0x80. Now it will. Now I want to give its clearly, one to drive 1 is 0x80 and you can drive dos are 0x81. What is step one and 2? I dunno. Precisely what does 0x80 and you will 0x81 denote? I dunno, a crazy & fortunate assume. And you can, from the maintaining the fresh society of machines doing everything you advised these to create, in place of that which you desired these to do, LILO has grown to become most, extremely capable of carrying out a footwear sector which is unbootable. It is completely unsuitable.
My resources partition is mirrored. You will find a copy of / into each other /dev/hda1 and on /dev/hdc1. As i give LILO that i need a boot markets strung towards /dev/hda and on /dev/hdc, and also to attach either /dev/hda1 or /dev/hdc1 while the sources partition, that’s what Needs. I do not wanted which L 40 forty forty crap. Really don’t wanted LI 80 80 80 both. I don’t want it bringing confused about what type is /dev/hda and you may which is /dev/hdc. We particularly do not want they creating a new view on which is which, compared to my personal save diskette.
