Tim,
You can find out how much each of your directories are using with the du
command, so you might cd to /usr and issue
du -a ./
then cd to /var
du -a ./
also, you have log files under /var/log, these files can get really big over
time and the info may not be of any value, so check out what you have under /
var/log, and see if you can free up some of that too (its possible you have
webserver logs(or whatever) that are humongous, and you dont even use your
webserver!) check out your messages, and syslog files, they get new stuff all
the time, if you dont need any of that info, and they are taking up 250 megs
you might tail the last 100 lines into another file, then move it to the
existing file...
also check out lastlog, wtmp, they can get big, and may not be of much use to
you (although they really can be handy if you have an intruder!)
as far as the partition deal goes... lets say you have 2g of data under /usr,
you want to make it its own partition. you have a 4 gig disk partition in the
system as hdc1.
Mount your partition as /new
mount /dev/hdc1 /new (or edit your /etc/fstab and put it in) then mount -a
so... do a df (this will show you disk free space, and the number of inodes
and size (hopefully both your disks will have the same size inodes to keep
this simple!) keep this info handy for comparison later...
no first copy your data from your /usr partition to your /new partition
heres a nice way using tar... (btw, cd to /usr first!)
tar cf - . | ( cd /new ; tar xvpf -)
now you will have a duplicate of your /usr on /new, do a du -a, and compare
that the sizes match (just incase... it will be, but its good to double check
incase)
now, the scary part... in the /usr dir, rm -rf *
that will wipe out your /usr dir...
now edit your /etc/fstab to include /usr on /dev/hdc1
unmount /new, then mount -a
(mount -a will mount everything in your fstab)
I dont think you need anything in /usr while performing this task, so you
probably dont need to boot the system on ramdisk (so your / partition isnt
mounted), but if you do, Im sure someone on this list will yell at me...
