Aumentare spazio disco freepbx centos vbox

Come prima attività verifichiamo le partizioni presenti:

#fdisk -l

WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.

Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt
Disk identifier: C477DAA5-AD6E-43EC-9B3D-D7AC891AF115

 2       147456      4243455      2G  Microsoft basic           <—— Partizione 1
 3      4243456     33550335     14G  Linux LVM                <—— Partizione 2

Quindi verifichiamo le partizioni utilizzate e lo spazio libero creato:

#parted /dev/sda print free

Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sda: 21.5GB
Sector size (logical/physical): 512B/512B

25.0GB 270GB 245GB Free Space <——– Spazio libero creato

Creiamo la nuova partizione utilizzando lo spazio appena creato:
#fdisk /dev/sda
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

eseguiamo la riscansione delle partizioni:
# partprobe -s
/dev/sda: msdos partitions 1 2 3

verifichiamo le partizioni presenti:
# fdisk -l

Quindi inizializziamo il PhisicalVolume per il suo successivo utilizzo nel nostro LVM:

#pvcreate /dev/sda4
Physical volume “/dev/sda4” successfully created.
# vgdisplay
— Volume group —
VG Name SangomaVG

Metadata Sequence No 4
VG Access read/write
VG Status resizable

Alloc PE / Size 5464 / 21.34 GiB
Free PE / Size 0 / 0
VG UUID Pcc0pu-mUbd-rOg0-V4iI-5jdO-sVUp-tk6Icd

Inseriamo il volume nel nostro volume logico SangomaVG:

# vgextend SangomaVG /dev/sda4
Volume group “SangomaVG” successfully extended

Infine estendiamo il filesystem esistente all’intero spazio disponibile sul volume:

# lvresize -r -l+100%FREE /dev/mapper/SangomaVG-root
Size of logical volume SangomaVG/root unchanged from <247.12 GiB (63262 extents).
Logical volume SangomaVG/root successfully resized.

A questo punto il nostro volume è stato allargato, lo possiamo verificare facilmente con il comando df -lh.
