Kako spremeniti velikost diska v FreeBSD

Operacijski sistem FreeBSD uporablja UFS (Unix File System) za datotečni sistem svoje korenske particije; drugače znan kotfreebsd-ufs

In the event of an upgraded disk size, we will illustrate how to expand this file system.

Prerequisites

1) To follow this tutorial, deploy one of the following:

• FreeBSD 11 x64

OR

• FreeBSD 10 x64

We utilized the following plan to begin our deployment:

CPU:        1 vCore
RAM:        1024 MB
Storage:    25 GB SSD

2) Prior to upgrading your intance, confirm its current disk allocation & partition table:

# df -h  
Filesystem         Size    Used   Avail Capacity  Mounted on
/dev/ufs/rootfs     24G    924M     21G     4%    /
devfs              1.0K    1.0K      0B   100%    /dev

# gpart show
=>      40  52428720  vtbd0  GPT  (25G)
        40      1024      1  freebsd-boot  (512K)
      1064  52427696      2  freebsd-ufs  (25G)

3) Upgrade your instance's plan:

1. Visit your Vultr management page
2. Select the instance that you'd like to upgrade.
3. Choose the "Settings" link near the top of the page.
4. Click the "Change Plan" link on the Side to show a dropdown menu of available upgrade choices.

In this case, we upgraded our plan to the following:

CPU:        1 vCore
RAM:        2048 MB
Storage:    40 GB SSD

1. Confirm New Disk Space

Čeprav se dodelitev diska sprva zdi enaka, gpartponazarja spremembo::

# df -h
Filesystem         Size    Used   Avail Capacity  Mounted on
/dev/ufs/rootfs     24G    924M     21G     4%    /
devfs              1.0K    1.0K      0B   100%    /dev

# gpart show
=>      40  52428720  vtbd0  GPT  (40G) [CORRUPT]
        40      1024      1  freebsd-boot  (512K)
      1064  52427696      2  freebsd-ufs  (25G)

2. Obnovite poškodovano particijo

# gpart recover vtbd0
vtbd0 recovered

# gpart show
=>      40  83886000  vtbd0  GPT  (40G)
        40      1024      1  freebsd-boot  (512K)
      1064  52427696      2  freebsd-ufs  (25G)
  52428760  31457280         - free -  (15G)

3. Spremenite velikost freebsd-ufsparticije

OPOZORILO!!!
Po priročniku FreeBSD :

There is risk of data loss when modifying the partition table of a mounted file system. It is best to perform the following steps on an unmounted file system while running from a live CD-ROM or USB device.

Ker je to nedavno nameščen primerek, ni občutljivih podatkov za varnostno kopiranje; vendar je v primeru nadgradnje primerka, ki je trenutno v produkciji, najboljša praksa, da izvedete varnostno kopiranje zunaj mesta, preden spremenite tabelo particij.

Ko ste pripravljeni nadaljevati, naredite naslednje:

# gpart resize -i 2 vtbd0
vtbd0p2 resized

# gpart show
=>      40  83886000  vtbd0  GPT  (40G)
        40      1024      1  freebsd-boot  (512K)
      1064  83884976      2  freebsd-ufs  (40G)

4. Razvijte datotečni sistem UFS

Če želite razširiti freebsd-ufsali /dev/vtbd0p2particijo, zaženite growfsstoritev:

# service growfs onestart
Growing root partition to fill device
vtbd0 recovering is not needed
vtbd0p2 resized
super-block backups (for fsck_ffs -b #) at:
 53224896, 54248448, 55272000, 56295552, 57319104, 58342656, 59366208, 60389760, 61413312,
 62436864, 63460416, 64483968, 65507520, 66531072, 67554624, 68578176, 69601728, 70625280,
 71648832, 72672384, 73695936, 74719488, 75743040, 76766592, 77790144, 78813696, 79837248,
 80860800, 81884352, 82907904

Lahko pa zaženete tudi naslednji ukaz.

growfs /dev/ufs/rootfs

5. Potrdite spremembe

# gpart show
=>      40  83886000  vtbd0  GPT  (40G)
        40      1024      1  freebsd-boot  (512K)
      1064  83884976      2  freebsd-ufs  (40G)

# df -h
Filesystem         Size    Used   Avail Capacity  Mounted on
/dev/ufs/rootfs     39G    924M     35G     3%    /
devfs              1.0K    1.0K      0B   100%    /dev
