Here is my disklabel layout :
16 partitions:
#size   offsetfstype   [fsize bsize   cpg]
  a:   307377   634.2BSD 2048 16384   304   # (Cyl.
0*- 304)
  b:   196560   307440  swap# (Cyl.  305
- 499)
  c:  42336000unused0 0 # (Cyl.0
- 4199)
  d:   245952   5040004.2BSD 2048 16384   244   # (Cyl.  500
- 743)
  e:   614880   7499524.2BSD 2048 16384   328   # (Cyl.  744
- 1353)
  f:  2868768  13648324.2BSD 2048 16384   328   # (Cyl. 1354
- 4199)

So f seems the last one (/usr).

*nods*

And if i leave /var as it is, only /usr must be reduced.

You wanted to grow /var instead, didn't you?

You could try growfs for /usr then, but you should backup anyway,
best everything.

But /usr has to be unmounted to make a backup, do it ?

Best you do it in single user mode. You can have it mounted
though (perhaps read-only, e.g. if you want to gzip the backup).

That case can't get the system running.

Thanks for your time

Kind regards,

Hannah.
