help help?: using mkfs -G

Post by David Lei Arjani » Sat, 01 May 1999 04:00:00

I am trying to grow / using the -G switch for mkfs, first I wanted to
increase swap by:

bash-2.02#  /usr/lib/fs/ufs/mkfs -G /dev/rdsk/c0t03d0s1 166160
Bad superblock; magic number wrong

what does this error mean?  also when I tried to grow / anyway...:

bash-2.02#  /usr/lib/fs/ufs/mkfs -G /dev/rdsk/c0t03d0s0 143038
/dev/rdsk/c0t03d0s0 is mounted on /; can't growfs

help help?
