FreeBSD 8.1, working toward a 4 jail system with vimage.
I have a pair of hd's in raid 1 for the host (18gb), and have setup 4 additional 18gb hd's each hd for a jail. Each jail uses full (nearly) 18gb scsi. After installing the host, I initially set up each jail with this code:
I run this code only once, to set up structure
Other 3 jails in a similar fashion.
I then got the jail running:
I run above code at each reboot
I did networking, entered jail, and pkg'd in xorg and firefox. (Only for jail 1, so far)
I exit'd jail and did a df from host:
Jail 1 is on /dev/da1s1d. Please look at what happened to my file space. I am noticing that my drive is now beyond fully allocated. My intention, of course, was to set up a dummy file that occupied the entire drive and that anything that I added after the construction, would go in place of the nulls that I first entered, filesize should not have changed. I know xorg is big, but 17g's? It appears that my assumption is incorrect and I would really like to understand why. If my additional software adds to the original filesize, then I should make the initial file very small ???? (bs<<1M) This isn't setting right with me, though. Why would I allocate at all? In Virtualbox, the same sort of allocation is done(fixed size mode)and all code, data resides within that initial space. I am way off on something, but what. BTW, jail 1, before installing xorg and firefox was the same size as jails 2-4.
