freebsd stable - Dec 2003 - newfs for insufficient inodes file system

hi sirs,

four months ago, i faced problem of insufficient inodes for /usr and one of 
solution for that, from Gregory Bond, was that to backup and do a newfs
for that file system.

today the situation become worst since i can not do any portupgrade even
/usr/local is a separate file system though.

am not an expert in FreeBSD but a plain user instead.  i have backed /usr up
already and going to do newfs on that.  my questions are that

      1) should i drop into a single mode first ?
      2) what parameter for newfs to pass to (i used sysinstall to do that
         and did make world and friends to upgrade my machine) ? 

below are my uname and informations about /usr

[firak] ~ # uname -a
FreeBSD firak.thai-aec.org 4.9-STABLE FreeBSD 4.9-STABLE #7: Sun Dec  7 10:19:07
 ICT 2003     firak@firak.thai-aec.org:/var/obj/var/src/sys/Firak  i386

[firak] ~ # newfs -N /dev/ad0s1f
Warning: Block size and bytes per inode restrict cylinders per group to 89.
/dev/ad0s1f:    1740800 sectors in 425 cylinders of 1 tracks, 4096 sectors
        850.0MB in 5 cyl groups (89 c/g, 178.00MB/g, 21504 i/g)
super-block backups (for fsck -b #) at:
 32, 364576, 729120, 1093664, 1458208

any helps and hints are welcome and appreciated.


with best regards,
psr

Urk, running newfs on /usr (or /) is major-league, heavy-duty,
potential-foot-shooting time.  Be VERY VERY careful. In fact, if you have to
ask how, there is a pretty good chance you'll wind up hopping and bleeding.

First step is to run "df -i" and see what the current space/inode
usage is.
Then check if the standard newfs params look OK (i.e. /usr currently has
substantially fewer than the 5x21504 inodes newfs would create in use.) 

Overall the best bet is probably to back up all the data and re-install, using 
adjusted newfs parameters if necessary.

hi sirs,

thanks to all who help me in my case.
after trying to backup, i face another big problems -- no more free hard disk 
available.  so i move the whole /usr/ports to /var and sym.link to that 
one instead.  this time i have a plenty of inodes free.

once again thanks so much for all helps.  and also Happy New Year to you all.
