Seems like a shame to boot a nice 9TB disk pack off a floppy Disk or a Pen drive. I mean you do what you have to but that just screams 'workaround' Or worrying about 1 minute longer boot cycle on 90 days+ uptime screams doesn't matter at all. it is workaround, but over strange BIOS software,

On our older servers that wouldn't even recognize a 2TB partition (which is where the OS was too), we used a CF card and CF card adapter to boot from. Slightly more gracious... CD/DVD drive isn't bad too. anyway - you don't change kernel every day. or pendrive. possibly floppy but i don't know

you talk about VM, not real memory. i don't think making 10GB swap is a problem. The problem is the time that it will take to fsck a 9TB filesystem. depends mostly of file count not size. my 1.4TB partition is checked shorter than 20GB squid partition ___

it will be most likely large 32K blocks, so quick fsck and little RAM In my experience with UFS2 and fsck you will want to have a gig of ram per TB of filesystem. You can get by with less sometimes, eventually you'll get bit. Most mere mortals don't take UFS2 past 6-8TB in production. There

That looks like what I need. I've got a seperate 32GB array to boot off of, so that's perfect. Now to just read some man pages. Thanks! How many memory do you have in this machine ?? To fsck 9 TB you will there is swap too . but my 1.4TB partition can be fsck'ed on 1GB RAM without swap.
