Hi guys

I've got a weird problem with my server which has 5 Gig swap space however it shows only 2 Gig by free -m

Do you have any idea?


[root@server ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sr0 11:0 1 1024M 0 rom
vda 252:0 0 55G 0 disk
├─vda1 252:1 0 50.1G 0 part /
└─vda2 252:2 0 5G 0 part [SWAP]



[root@server ~]# free -m
total used free shared buffers cached
Mem: 2006 1929 76 0 9 30
-/+ buffers/cache: 1889 116
Swap: 2047 145 1902
 
You have to identify which causing the swapping in your system.
Use top / htop and check the memory usage.
 
Your (virtual) server is installed with 1 GB of ram resulting in a default of 2x1GB swapspace.
Afterwards your vda2 is expanded to 5GB but the swap fs is not resized.

Usually you'll need a few swapoff, resize2fs, mkswap, swapon commands that might have some different parameters depending on the filesystem you use.

Google 'expand swap partition ext4' (or lvm).

It is weird, are you sure you setup swap correctly. I guess you did wrong configurations while setting up swap :)

I also am using swap for my hosting server and it is displaying correctly what I set.

Following this article https://forumweb.hosting/13622-how-...-memory-(swap-file)-on-linux-vps-systems.html

Hope it helps!
