Subject:   Root partition size too small for FreeBSD 10.1?
Message-ID:  <54C3D0A0.1000500@webtent.org>

Next in thread | Raw E-Mail | Index | Archive | Help
I have a server I tried to upgrade to 10.1-RELEASE and it gave me out of 
disk space errors when it came time at the end to making changes to 
/boot/kernel. I reverted the snapshot taken on this VPS back to 8.4 for 
now. The root partition is 85% used of a 500MB, and since more than half 
the used space is in /boot/kernel, I think its the new kernel size that 
is the issue and the root partition will have to grow? If that is the 
case, I would have to make some room....

root@www:/usr/local/etc # df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/da0s1a 484M 378M 67M 85% /
devfs 1.0k 1.0k 0B 100% /dev
/dev/da0s1d 9.5G 1.6G 7.1G 18% /usr
/dev/da0s1e 9.2G 2.7G 5.7G 32% /var
/dev/da1s1 19G 4.0G 13G 23% /www

Looking at the handbook, perhaps I could use the swap to extend the root 
partition and resize /var to add swap back in single user mode? And 
would that be enough space, still less than 1GB.

root@www:/usr/local/etc # gpart show da0
=>      63  41942977  da0  MBR  (20G)
         63  41929587    1  freebsd  [active]  (20G)
   41929650     13390       - free -  (6.6M)

root@www:/usr/local/etc # gpart show da0s1
=>       0  41929587  da0s1  BSD  (20G)
          0   1024000      1  freebsd-ufs  (500M)
    1024000    524288      2  freebsd-swap  (256M)
    1548288  20480000      4  freebsd-ufs  (9.8G)
   22028288  19901299      5  freebsd-ufs  (9.5G)

Thanks for any help or pointers...?
