Installation failed: open3: exec of sgdisk

[smetairie]

I reinstall proxmox 6.0.1 from ISO, the first time it worked. I did 3 nodes but the cluster command pvecm add .. failed. I suspected bad network configuration notably with dns / dhcp.

Now I have this message popup in the proxmox VE installer when it's starting, on each node I try to reinstall.

"open3: exec of sgdisk -n2:1M:+512M -t2:EF00 -n3:513M:0 -t3:8E00 /dev/sda failed ... ... proxinstall line 398"

When i click to [OK] to this popup, i'm invited to press switch to console, I read this : see file attached

" ...

hi,

that's really weird. just to rule out data corruption on the install medium, could you check the hash of the ISO file to see if it matches, and then burn it again on usb and try again to see if that changes anything?

I extract from the code source this :
my $partitions = `lsblk --output kname --noheadings --path --list $disk`;

That means lsblk failed

I removed with fdisk every partition on targeted disk and now that works

I think reinstall on the same node , same disk , has an issue.

this is what we have in the partition

hi,

i'd like to try and reproduce this.

which filesystem did you select in the first installation?

maybe you can send a screenshot of the last screen where all the options you chose are shown before you verify.

 

[smetairie]

default ext4

 

[oguz]

it seems to work here.

can you tell me about your hardware?

i think there's might be something wrong with your disk, because the I/O error with vgchange happens earlier (it runs vgchange -an to deactivate the VGs in the first place before beginning the partitioning)

maybe you could try to run the installer in debug mode, and check dmesg.

(while running in debug mode, you can switch to console with ctrl+alt+f1)

Ok I'll check with another node, I post the reply here
Thanks !
