Recommended Partition for cPanel WHM Centos 7

[dsteam]

Dear Seniors and Expert Sifu,

Recommended Partition for cPanel WHM Centos 7
Server spec : 2x2TB HDD, 32GB Ram
Mainly for host customer website and emails

1 Primary XFS /boot 2GB
2 Primary XFS / ( All Space left )
3 Primary SWAP swap 16GB

is it need any other partition? example /home ?

And Type should I use XFS Or Ext4?

Please advise
Thank you very much

Hi dsteam

The partition style is ok, it is not necessary to create /home as a separate partition. it will work perfectly fine. but some says separating /home is good.. no other partition is needed in generally. if you separate /home as a different partition make sure to give necessary space to / not less than 150GB if its a big shared server, as MySQL dbs are stored in /var/lib/mysql and all installed softwares goes to /

Also, you can go with xfs filesystem as it supports intensive I/O workloads than older filesystems.

And another suggestion is to go with Almalinux8 instead of centos7

Hello techAMIGO,

Thanks for your reply, helps alot.

How ab Almalinux8 and Cloudlinux OS Shared?
If I want to limit the resources like LVE manager?
What is your suggestion?

Thanks again

@dsteam

If you want to limit the recourses then go with CloudLinux, even if you go with Almalinux you need to convert the OS to CloudLinux to use the LVE manager ( Cloud Linux manager) , but conversion is not a big deal as cloudlinux is giving their own script to convert to it.

@techAMIGO

Yes, cloudlinux is giving their own script to convert to it, but when I try to setup found another error >.<

From the warning msg, it advise me refer

https://cloudlinux.zendesk.com/hc/en-us/articles/360021620699

But I not sure how to do it

 

[techAMIGO]

Ok,, it seems there is some issues with the boot partition or issues with mounting. would you show me the contents of /etc/fstab .

@techAMIGO
Here is the content
TQ^^

Ah yes,, As I thought the cloudlinux will not support LABEL with multiple partitions, you need to remove the LABEL from fast and add uuid instead of it , so it will point only to a single partition.

for more info you can refer the doc

https://cloudlinux.zendesk.com/hc/en-us/articles/360021620699-CloudLinux-7-8-kernel-unable-to-boot-on-UEFI-enabled-soft-raid-1-server-

also mean time don't reboot the server too.

 

[dsteam]

Yes, I read and follow, but I do not know the command for " 1. Replace LABEL or UUID with a path to a partition,"
Google unable to found the guide

 

[techAMIGO]

Hi,
find the exact partition which is mounted to /boot/efi and also UUID
both can be see with the command

 lsblk -f

then comment out current entry from fstab and add it as new entry for /boot/efi with the UUID


Make sure to double confirm you're replacing the correct line and adding the correct entry else the server won't boot the kernel

 

[dsteam]

Hi techAMIGO,

I am not expert on command code, I only know follow the guide step by step ^^
Attached file is lsblk -f Result

I have no idea how to do it next....

 

[techAMIGO]

From the screenshot I can see the /boot/efi is mount from /dev/sdb1 which means all UEFI boot files are located under sdb1.

so the entry in fstab should be like

  /dev/sdb1  /boot/efi  vfat   defaults 0  0

after that the script will work fine..
but, I recommend contacting a sysadmin to perform a check in this case as the server might lead to unbootable if the boot files are missing in the partition, so I will not recommend doing anything blindly.

 

[dsteam]

Hi @techAMIGO

It show me permission denied

 

[techAMIGO]

HI @dsteam,

It's not a command .
it needs to be added to /etc/fstab file instead of the current LABEL entry, Be careful while editing /etc/fstab if you don't know how to edit, please don't for it, wrong entry makes the server unbootable.. so I'm again suggesting to contacting a sysadmin to perform the same if you're unaware how to do it. It can be done in a few minutes.

so again,
1) edit the /etc/fstab file
2) remove the line with LABEL=EFI_SYSPART
3) add the line

   /dev/sdb1  /boot/efi  vfat   defaults 0  0

4) continue the cloudlinux script

Thanks, @techAMIGO !

And yes, no one should be creating new machines with CentOS 7 at this point.
