Hello,

I have installed VestaCP from scratch. I want to increase swap partition to 8GB, but don't know how to do it. Thank you in advance.

Here is the result of lsblk command:

[root@cpanel /]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 220G 0 disk
├─sda1 8:1 0 500M 0 part /boot
└─sda2 8:2 0 219.5G 0 part
├─vg_cpanel-lv_root (dm-0) 253:0 0 50G 0 lvm /
├─vg_cpanel-lv_swap (dm-1) 253:1 0 3.9G 0 lvm [SWAP]
└─vg_cpanel-lv_home (dm-2) 253:2 0 165.6G 0 lvm /home
sr0 11:0 1 1024M 0 rom

do this as "root" :

Code: Select all

fallocate -l 8G /swapfile
ls -lh /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

Check if it is correctly done

Code: Select all

swapon -s

Edit your fstab to survive reboot

Code: Select all

nano /etc/fstab

Code: Select all

/swapfile   none    swap    sw    0   0

Code: Select all

reboot

and verify again with

Code: Select all

swapon -s

Thanks. I have some questions:
1. When I want to add swap it says: fallocate: /swapfile: fallocate failed: Text file busy.
2. Here swap is partition or file?
3. Which method do you recommend about partitioning? I can do custom partition or let VestaCP do its partitioning? If I do custom partitioning it will be so:

HDD 220GB
sda 1 - / - 50GB
sda2 - /home - 162GB
sda3 - /swap partition - 8GB

Is it correct or do I have to add something here? Vestacp added /boot - 500mb. Is it necessary?

You need to switch OFF Swap first in order to release OS control over it.
