Freebsd Cannot Work Out Which Disk We Are Booting From
If you need a little reminder, you can run the command below to see your drives. Yep, and in this case NSD is currently 90% faster with prospects to push it even higher with some further kernel changes (so far we have improved it by 45%). Perhaps an alternative install method, or perhaps the Loader is not configured properly for the R900. Can't work out which disk we are booting from. navigate here

I'm not entirely sure how much difference spinning the disks down would make to the power usage - it's a personal choice. This code lives in the bootblocks on the partition superblock of the installed FreeBSD system.

This laptop is a nightmare: the Linux kernel hates my ACPI and my sound card; OpenSolaris hates my hard drive; and BSD refuses to boot from ZFS partitions… Reply ↓ Josh I use ZFS for root on all my storage servers, and I have deliberately failed drives to simulate failures without any trouble at all. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. However, I was wondering if any extra steps are required when upgrading world.
It will be educational. It booted fine, but attempting to use Fixit generated an error that there was no media present. For me, the extra capacity was worth the extra power usage. Cheers, Peter Smerdon.

when I simulate one disk missing, it cannot boot any more. I searched high and low for a clue to no avail. Unavoidable for booting from it however. his comment is here Unfortunately I wasn't able to load the kernel (/boot/kernel/kernel) directly from grub.
Ideally I want to take the faulty disk offline, reinsert a new one without having to go into single user mode. http://perforce.freebsd.org/chv.cgi?CH=158721 Andrew: Another patch to commit. --HPS Next Message by Thread: pendrive recognizing problem Hello, First of all, please bear with me were this not the appropriate list for my question.

In case the ~/.bash_history file can also be written to another location that the root alone can access then perhaps we can solve this problem.

Does not help. Peter Smerdon. How can you make the file readable and writeable by root alone? I'm using ULE and device polling.
Now whilst trying to boot I get BTX loader 1.00 BTX version is 1.02 Consoles: internal video/keyboard BIOS drive C: is disk0 BIOS drive D: is disk1 BIOS 639kB/3668736kB available memory That's what confused me. Anyway, the motivation here is not a DNS deathmatch, but part of our ongoing effort to look for aspects of FreeBSD performance that can be improved. That's going to be interesting, as by default this motherboard wants to boot from, and see the updater on, a floppy drive (remember those) - this box doesn't have a floppy.
