/var too small [was Gap of years = loss of memory!!]

Hi
This is the sort of thing I used to do regularly but not having done this task
for a few years I feel the need to check up on the best way to deal with the
circumstances described below.
I decided to change the subject - maybe you thought the original was spam :-)
I have a freebsd system with the following
hard drive configuration:
$ df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad6s1a 253678 44804 188580 19% /
devfs 1 1 0 100% /dev
/dev/ad6s1e 253678 15732 217652 7% /tmp
/dev/ad6s1f 148665266 18848290 117923756 14% /usr
/dev/ad6s1d 253678 107022 126362 46% /var
The full output from dmesg.boot is included as a postscript (all comments
welcome). Its last two lines are:
Opened disk da1 -> 6
Mounting root from ufs:/dev/ad6s1a
The motherboard is an Abit VA-20 with two SATA slots on the motherboard-
SATA1 & SATA2
/dev/ad6 is a 160G SATA hard drive currently connected to the SATA2 slot (dont
know why!)
(a) /dev/ad6s1d [ /var ] is far too small for my needs
(b) With the development project I am embarking on /usr will also be small to
hold the development files as well as other stuff.
(c) I have therefore bought a new 200G SATA drive to add to the system.
(d) I wish to allocate 40G to /var and
(e) 160G to /dev
(f) rename /var to /var.old
(g) move /var.old to /var
(h) have /var.old mounted as /logs
(i) At the same time I also propose increasing memory from 1G to 2G which will
hopefully speed up my compiling a little.
OK so far .. now
If I put the new drive onto SATA 1 with the exiting drive remaining on SATA2
the bios expects to boot from CD. Currently the bios is set to boot from HDD0
but if I change the bios to HDD1 it makes no difference. The system does not
boot at all.
Unless I have missed something it seems the bios cannot be set to allow boot
from SATA2 if a drive is present on SATA1.
If I put the existing drive onto SATA 1 with the new drive onto SATA2 then the
root mount fails. The existing drive appears to be recognized as ad4 so if my
recollection is correct the first step would be to alter /etc/fstab to read:
/dev/ad4s1b none swap sw 0 0
/dev/ad4s1a / ufs rw 1 1
/dev/ad4s1e /tmp ufs rw 2 2
/dev/ad4s1f /usr ufs rw 2 2
/dev/ad4s1d /var ufs rw 2 2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
and the system should mount OK???
IS that correct?
I want to get this right first time (if possible!!)
Then presumably I can
(a) use sysinstall to add the new drive which should presumably mount as ad6?
(b) Create partition ad6s1a (+/-40g)
(c) Create partition ad6s1b (+- 160G)
(d) I am inclined to use sysinstall to mount the first partition ad6s1a
as /logs and
(e) the second partition ad6s1b as /dev
(f) reboot - resumably sysinstall will automatically add the entries
to /etc/fstab and then I can
(g) copy the contents of /var to /logs
(h) switch the fstab entries for /var and /logs
And I should boot up OK
Is this a sound plan
In light of the added memory should I modify the plan to allow for additional
swap space on the new drive?
Thanks in advance for any input
David
