pwd.db too big for / partition

[Marcelo Maraboli]

Hi

my / partition has only 73.196 Mbytes available and since I
have 22.000 users, I now cannot change anyone´s password..

root at server:~$ passwd marcelo.maraboli
Changing local password for marcelo.maraboli
New Password:
Retype New Password:

/: write failed, filesystem is full
pwd_mkdb: write old: No space left on device
passwd: pam_chauthtok(): error in service module

How can I rezise the "/" partition or move the spwb.db
and pwd.db files to another partition ?? (each of them is 44 Mbytes)

thanks.
