Resize disk centos7

[Andrea Carnevali]

Hello.
I tried to enlarge a disk connected to a VM centos7 where I installed a zimbra mail server.
In this I say I store all the emails and then after 3 years I want to go from 250Gb to 350 Gb.
Without turning off the machine, I used the "resize disk" command.

Now the partition is :

Disco /dev/vdb: 322.1 GB, 322122547200 byte
255 testine, 63 settori/tracce, 39162 cilindri
Unità = cilindri di 16065 * 512 = 8225280 byte
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Identificativo disco: 0x00081831
Dispositivo Boot Start End Blocks Id System
/dev/vdb1 1 32636 262142976 83 Linux

I have not turned off the vm centos but only restarted and the filesystem is this:

Filesystem Size Used Avail Use% Mounted on
/dev/vdb1 246G 232G 2,0G 100% /opt/zimbra

Can you give me a guide now on how to enlarge the filesystem and show it the whole disk?



Thank you

Andrea

In the guest you have to
- extend the partition ( /dev/vdb1 )
- then run

resize2fs /dev/vdb1
