I've downloaded the image and written it to a microSD card and booted CentOS 7 on my Raspberry Pi 4. I'm using a 256GB card so I wanted to expand but was unable to do that as rootfs-expand is missing:

[root@localhost ~]# cat README
== CentOS 7 userland ==

If you want to automatically resize your / partition, just type the following (as root user):
rootfs-expand

[root@localhost ~]# rootfs-expand
-bash: rootfs-expand: command not found

Thank you so much. I installed the AARCH64 image on a SD card and resized 10GB more for my first installations. I have reached the rpm world finally after so much googling.

Is there a CentOS version for the Odroid N2? Propably the most powerfull ARM V8. I will get one in a few days.

Again thak you. I am so lucky. Though I am with Linux very long I suspended for two years after my first attempts to get ARM64 running useful. That was with the Odroid C2. The only useful hardware I knew at this time because 1GB RAM is way to small today. 2GB are fair and 4GB are OK.

I found many things chaged these two years. I installed XRDP on two systems and it worked. Last time I needed to install an HDMI to VGA adapter for correct config and use VNC.

How did you resize the image?

Put the SD card in a linux machine with gparted installed. Select the SD card on the right top. Unmount the EXT partition and chose resize. Modify the size. When you shrink to save space for a snapshot make sure to leave some space for the next boot.

Klick "apply" and wait to finish.

Unmount the other partion(s) and remove the SD card.

Hope adding on to this thread is ok. I've tried to get an SSD connected via usb3 configured as '/' following approximately this https://jamesachambers.com/raspberry-pi ... sh-drives/ blog post. I know it's Raspbian, but the result has been...interesting.

Code: Select all

[root@localhost /]# mount | grep ^\/dev
/dev/mmcblk0p3 on / type ext4 (rw,noatime,seclabel)
/dev/sda1 on /boot type vfat (rw,noatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)

Code: Select all

/dev/mmcblk0p1: SEC_TYPE="msdos" UUID="16CB-DE38" TYPE="vfat" 
/dev/mmcblk0p2: LABEL="_swap" UUID="8322aeee-a657-49db-b257-46d8e4467591" TYPE="swap" 
/dev/mmcblk0p3: LABEL="_/" UUID="96a7d256-5af0-4b28-91c0-c414e8249b38" TYPE="ext4" 
/dev/sda1: SEC_TYPE="msdos" UUID="16CB-DE38" TYPE="vfat" 
/dev/sda2: LABEL="_swap" UUID="8322aeee-a657-49db-b257-46d8e4467591" TYPE="swap" 
/dev/sda3: LABEL="_/" UUID="562d2eb7-5971-4f07-b009-c6c39d4d35b6" TYPE="ext4" PTTYPE="dos" 
/dev/mmcblk0: PTTYPE="dos" 

Code: Select all

[root@localhost boot]# cat cmdline.txt
console=ttyAMA0,115200 console=tty1 root=UUID=562d2eb7-5971-4f07-b009-c6c39d4d35b6 rootfstype=ext4 elevator=deadline rootwait

I would like to get at least /var, /usr, and /home from the ssd mounted. In other attempts, I've gotten /home and I think /usr mounted, but, getting that last mount has been problematic, it could be due to something with SELinux, but, I thought I had set Permissive in /etc/selinux.conf and the pi 4 just wouldnt boot. I would guess I've run into something with the device overlay tree, but I don't know how to update it after a first read-through of the docs. I'm running C7 with the experimental 64 bit image listed in this thread... (thanks for working on that btw!)

So, a bit of news, I have TEST version a TEST image for a TEST rpi4 using TEST aarch64.
For those who want to TEST, here's te TEST link https://people.centos.org/pgreco/CentOS ... al-4-1908/
I have been using it for a few days and haven't seen anything strange, but it's been only cli/ssh.

Pablo.

P.S.1 ) Did I mention this is a TEST? :D :D
P.S.2 ) I compiled some things and made the image itself in machines other than CentOS' servers, if you don't trust me, don't use it :mrgreen: :D
Thanks for this awesome work!

How usable is this iso or should I fallback to 32bit?

My goal is to run a few things like httpd, mysql, dotnet, no gui required mainly cli/ssh, etc, pretty much a dev server for testing.
