petasan-3.0.1 iso installation fails

Hi all,

we planned to install petasan on 5 supermicro servers, type CSE-826 (quite old), Adaptec Controller ASR-5405z.

A RAID1 array is configured, trying to install petasan OS here.

We have additional 10 JBOD disks for the ceph storage.

The installation is cancelled with the following errors:

mount: mounting /mnt/cdrom/petasan.squashfs on /mnt/petasan failed: No such file or directory

mount: mounting /mnt/cdrom/installer.squashfs on /mnt/installer failed: No such file or directory

...

This error repeats for various filepaths, also mkdir /mnt/installer-merged/dev/pts fails.

It finally loads VESA graphics driver and the last stdout message is:

Chroot: Cant execute /root/installer.sh: No such file or directory.

Obviously it does not find the target mounts, is the culprit missing disk/backplane drivers?

Any help appreciated :).

Thanks so much in advance.

Kind regards

Can you check maybe the iso is corrupt, try re-downloading.  Else if it still happens, it maybe hardware related to your server, or you have very little ram memory.

Thanks for your quick reply.

I already re downloaded the iso file and flashed to another USB stick.

RAM should not be an issue (32GB), as I said, I have the feeling the disks are not recognised by the installer.

Do you happen to know which OS the installer is based on?

Maybe a solution is to inject specific drivers to the installer (though not sure yet which drivers I need).

Kind regards

This is very strange, it seems the iso is read to some degree as it loaded the install script, yet it does not find the squashfs from the iso

Does the boot screen of the installer show after the yellow PetaSAN 3.0 message, on third or fourth like a message like Detecting PetaSAN install device  with volume label PETASAN:  does it show found device XX,  does it show it detected the install device ?

The iso is based on Ubuntu 20.04 and kernel SUSE 15 SP1

Hi and thanks again for your quick reply.

It recognizes the device labeled "petasan" but failed with the very next step mounting /mnt/cdrom/petasan.squashfs on /mnt/petasan.

 

But you gave me the crucial hint :), Ubuntu 20.04 installs and works fine on my machines.

I redownloaded and flashed the iso image a third time, this time using rufus (used etcher before) and out of a sudden it worked.

No clue if etcher broke the medium...

Thanks you so much.

Kind regards
