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. attach 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 relax and play the new speculating game of just what info is on what control sucks
The bad when you have mirrored you resources partition. In these instances, your have a tendency to end up handling one illustration of the brand new reflect, rather than the whole thing. You will find an option complicated factors as to how that becomes wedged this kind of the right position, but it’s just not unusual. Anyhow, in cases like this, you’ve got one or two (or even more?) duplicates off /etc/fstab during the play. Which becomes made use of will get a purpose of the latest bootloader, the save diskette, new haphazard BIOS push numberings system, and you may agent confusion. Into any given restart, the fresh new /etc/fstab you to gets used might or might not end up being the you to definitely you only got complete modifying.
Ext2fs labels. Their great you could place a tag on ext2fs having the latest e2label demand. However, are you aware that if one makes a great RAID-1 reflect /dev/md1 out-of /dev/hda1 and you can /dev/hdc1, and put an Ext2fs title inside it, that all about three of these gadgets can get the same ext2fs name? Brands are needed on stop-tool level, and title needs to accept the true shops mass media becoming labelled. The brand new attach demand, and /etc/fstab need to use take off-equipment labels, perhaps not document-program brands.
The present day Linux md subsystem uses ‘raid superblocks’ to save good UUID and cache almost every other info. However, there are no products that truly will let you look at that details, neither to place a tag inside. Never attention that you have to have their partition method of is 0xfd and not 0x83, and you may yada yada yada.
Possibly MSDOS-compatible disk drive partition dining tables is actually completely wrong? Maybe one of the most other partition table looks is better? In the event the I’m not powering MSDOS otherwise Windows for the host, I really don’t have to take the fresh MSDOS partition desk. Where’s the fresh HOWTO you to definitely discusses content at this top? How do we score tools to utilize this stuff?
File-system labels was fascinating, however they are perhaps not a whole respond to
Brand new LILO (type twenty five.5.3.1) has gone crazy. My personal history form of LILO don’t grumble one each of my hard disk drives had been from the https://www.datingranking.net/pl/catholic-singles-recenzja 0x80. Today it does. Now I have to tell its explicitly, one to drive step one is actually 0x80 and you can push dos was 0x81. What is 1 and you will 2? I dunno. How much does 0x80 and you will 0x81 denote? I dunno, a crazy & fortunate guess. And you may, in the maintaining the fresh new tradition out-of machines starting what you advised these to perform, in place of what you desired these to carry out, LILO is now most, really effective at undertaking a boot field that is unbootable. This will be completely improper.
My personal supply partition is reflected. You will find a copy regarding / towards each other /dev/hda1 and on /dev/hdc1. Once i share with LILO which i want a boot field strung on /dev/hda and on /dev/hdc, and to mount often /dev/hda1 or /dev/hdc1 due to the fact sources partition, that is what I want. Really don’t need which L 40 forty 40 shit. I really don’t want LI 80 80 80 possibly. Really don’t want it bringing unclear about which is /dev/hda and which is /dev/hdc. I especially wouldn’t like it discovering a different advice on what was and therefore, than the my rescue diskette.
