Hello everybody,
I have a big problem during installation of PVE9.1. Here are facts :
  • 3 servers Dell R710 with 4 disks in hardware raid5 each
    • Same version of Idrac6
    • Raid is made with Perc6i
  • USB key made with dd command on debian 12
I succeeded installing on the first server. I have the same error on the two other during the installation :

Bash: 
DMAR: ERROR: DM PTE for vPFN ’some hexa numbers’ already set (to hexanum not ’another hexanumber’)
same line many times with hexa numbers differents
SQUASHFS error: zstd decompression error: 20
SQUASHFS error: zstd decompression failed, data probably corrupt
SQUASHFS error: failed to read block 0x1f21bbf3: -5

It finished with an Installation aborted - unable to continue.
I used the same USB key for the 3 servers, only few minutes between installations. And I had exactly the same errors on the servers 2 and 3.

If you have an idea of why, I take advices.
 
Hi,

I'd first try to update UEFI/firmware (which usually is different from the IPMI, i.e. iDRAC in your case), never hurts - these often fix things esp. with regards to Linux compatibility.

Although on a hunch these errors may have not have anything to do with squashfs error during the installation.
Can you try some other USB flash drive? Maybe it has gone bad, and the first one worked by accident.
Or booting the ISO directly via iDRAC.
 
Thx for your reply. I did the update of Idrac6 to the last version (2.92) before installing PVE.

I tried differents USB keys. 2 made with dd, and 2 made with Rufus with dd mode as said on manual.

I will search how to boot directly via iDRAC, I’m not sure it’s possible with these version.

but the problem is to put the iso on the server.
Click to expand...
Usually the relevant .iso has been downloaded to (and is stored on) the same PC where I am using the web browser for iDrac on = my local PC.

The whole point of this mechanism is that the .iso is not copied to the server ahead of (boot-) time but used "directly" via iDrac from the disk on my local computer for booting.
 
I finally find the solution. I suceeded an installation with a DVD for one of the two (it’s strange but it worked with only one) and I used a VM with W7 and java6 to access to virtual media and used it to install PVE.

Thx for your help.
