• If you are still using CentOS 7.9, it's time to convert to Alma 8 with the free centos2alma tool by Plesk or Plesk Migrator. Please let us know your experiences or concerns in this thread:

  • Please beaware of a breaking change in the REST API on the current Plesk release (18.0.62).
    Starting from Plesk Obsidian 18.0.62, requests to REST API containing the Content-Type header with a media-type directive other than “application/json” will result in the HTTP “415 Unsupported Media Type” client error response code. Read more here

Question CentOS2Alma conversion: Your expectations and experience?

rkbonatto said:
Why update from Centos7 to Alma when plesk in Centos receives updates before Alma, and Alma has been presenting problems and instabilities with Plesk?
Click to expand...
That a rather bold statement, that simply isn't true. AlmaLinux is an excellent and stable distro, used thousands of Plesk customers. We are not aware of any stability issues. If you have encountered any issues I recommend opening a ticket with Plesk support for an investigation.
 
Successfully upgraded two servers with no issues, but the third fails claiming it needs "At least 358MB more space needed on the / filesystem."

However, output of df -m shows:

Code: 
Filesystem              1M-blocks  Used Available Use% Mounted on
devtmpfs                     3971     0      3971   0% /dev
tmpfs                        3982     0      3982   0% /dev/shm
tmpfs                        3982    10      3973   1% /run
tmpfs                        3982     0      3982   0% /sys/fs/cgroup
/dev/mapper/centos-root    120318 30485     89834  26% /
/dev/vda1                     497   254       244  51% /boot
tmpfs                         797     0       797   0% /run/user/0

26% equates to ~30GB of space. Any ideas how to resolve this?

I've posted an issue to the centos2alma GitHub issues page.
 
Updated 3 servers had a few issue with the dovecot had changed the nameing sheme of its min ssl req but just had to comment out the wrong one and two domains did not have php versions but it was easly fixed by adding php version so great work :)
 
Want to upgrade one of my 5 servers - same problem - failed with "At least 835MB more space needed on the / filesystem."

The script makes the first boot - so i have to revert via snapshot!
Will try tommorow another!

Is it possible that make the acronis-plugin some difficults? Should it deinstalled for the conversation?
 
The /dev/mapper/centos-root path is strange. This is not a normal partition as it would come with a true, physical CentOS installation. It's probably a virtual path. What's the real physical device underneath? And what's its status?
 
Hi, i do a conversion of another server without problems. Run smooth.
But i try the above one again. I check the kernel-modules, delete old php versions - all fine.
But i get following error-message:

Whats going wrong on this machine?

Bye, Klaus
 
I recently went through the CentOS to AlmaLinux conversion, and overall, it was pretty smooth. The AlmaLinux community has been super helpful, and the documentation is thorough. I expected some minor hiccups, but everything went pretty seamlessly.
 
We have the same problem on another server! One server we could convert without problems, two others failed with more space needed on the / filesystem, while there are 70GB free!

selinux is disabled: SELinux status: disabled
What can we do?
 
the only difference between the server who works and the servers they want work is an installed plesk acronis. Can this be the problem (dkms?)
 
This should be advertised inside the Plesk control panel as very few pleask users visit the forum and are unaware of this change!
 
For anyone having the following error:
"checking if there is more than one NIC interface using ketnel-name' not met:"
"checking if there is more than one NIC interface using kernel-name' not met:"
Please mind that it seems this software has quite some typo's,for which I created a fork, and included the new text hear just in case someone is searching for it in the future.
chatGPT created a script to easily rename the network interfaces which served me very well:
pastebin.com

#!/bin/bash# Function to get user inputget_input() { read -p "$1: " i - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.
pastebin.com pastebin.com
Bash: 
#!/bin/bash
 
# Function to get user input
get_input() {
    read -p "$1: " input
    echo $input
}
 
# Backup reminder
echo "Always backup your server data before making changes."
read -p "Have you backed up your data? (yes/no): " backup_confirm
if [ "$backup_confirm" != "yes" ]; then
    echo "Please backup your data before proceeding."
    exit 1
fi
 
# Get the current NIC names and MAC addresses

ifconfig | grep -o -E 'eth[0-9]' | while read -r nic; do
    mac=$(cat /sys/class/net/$nic/address)
    echo "Interface: $nic, MAC Address: $mac"
    new_name=$(get_input "Enter new name for $nic (e.g., ens192)")

    echo "Updating udev rules..."
