복잡할 거 같지만 단순합니다. 사용자들이 freebsd 에 익숙하지 않을 뿐입니다. 편하게 생각하세요...
사용하시는 가상서버호스팅에서 서비스상 디스크 크기 늘리시고요.. (회사마다 관리자 페이지가 다르겠죠..)
이제 나머지는 서버 콘손에서 실제 늘리는 작업만 하시면 됩니다.
회사별 장치명이나 등등... 약간씩 차이는 있습니다만 원리는 똑같습니다.


Found myself exploring /etc/rc.d/growfs. Discovered it worked when called as a service.

FreeBSD 10.2> df -h

Filesystem      1K-blocks    Used    Avail Capacity  Mounted on
/dev/gpt/rootfs  20307196 5350028 13332596    29%    /
devfs                   1       1        0   100%    /dev

FreeBSD 10.2> service growfs onestart

Growing root partition to fill device
vtbd0 recovered
vtbd0p3 resized
super-block backups (for fsck_ffs -b #) at: ###, ###, ...

FreeBSD 10.2> df -h

Filesystem      1K-blocks    Used    Avail Capacity  Mounted on
/dev/gpt/rootfs  29442440 5350028 21737020    20%    /
devfs                   1       1        0   100%    /dev

Examined $rootdev in /etc/rc.d/growfs and found to have the value of gpt/rootfs
 

So for the ‘hip’ crowd, we do

FreeBSD 10.2> sysctl kern.geom.debugflags=16

kern.geom.debugflags: 0 -> 16

FreeBSD 10.2> gpart show

=>       3  44040224  vtbd0  GPT  (30G) [CORRUPT]
         3        32      1  freebsd-boot  (16K)
        35   2097152      2  freebsd-swap  (1.0G)
   2097187  41943040      3  freebsd-ufs  (20G)

FreeBSD 10.2> gpart recover /dev/vtbd0

vtbd0 recovered

FreeBSD 10.2> gpart show

=>       3  62914555  vtbd0  GPT  (30G) **no longer corrupt**
         3        32      1  freebsd-boot  (16K)

   2097187  41943040      3  freebsd-ufs  (20G)
  44040227  18874331         - free -  (9.0G) --> 요 부분이 새로 추가한 용량 되겠습니다. 이제 위에 3번에 합쳐 크기 조정해야죠...

FreeBSD 10.2> gpart resize -i 3 vtbd0

vtbd0p3 resized

FreeBSD 10.2> gpart show

=>       3  62914555  vtbd0  GPT  (30G)
         3        32      1  freebsd-boot  (16K)
        35   2097152      2  freebsd-swap  (1.0G)
   2097187  60817371      3  freebsd-ufs  (29G)

FreeBSD 10.2> df -h

Filesystem      1K-blocks    Used    Avail Capacity  Mounted on
/dev/gpt/rootfs  20307196 5350052 13332572    29%    /
devfs                   1       1        0   100%    /dev

FreeBSD 10.2> growfs -y /dev/gpt/rootfs

super-block backups (for fsck_ffs -b #) at: ###, ###, ...

FreeBSD 10.2> df -h

Filesystem      1K-blocks    Used    Avail Capacity  Mounted on
/dev/gpt/rootfs  29442440 5350052 21736996    20%    /
devfs                   1       1        0   100%    /dev

All the while mounted.

I’m not sure if sysctl kern.geom.debugflags=16 is really needed now as the /etc/rc.d/growfs script makes no attempt to call it, and it is successful.
