Dear All,
My configuration is a Dell PowerEdge R720 that comes with a dual 1GB SD card in RAID1 on the motherboard (rest being 2x Xeon E2650, 32GB RAM, 2x 300GB SAS in RAID1.
I didn't realize the 1GB of the SD cards were not enough to install ProxMox. My first installation failed saying that the HDD was not big enough.
Then I moved to installing on the RAID1 made of the 2 SAS drives. Again the installation failed saying it was unable to create VG on the system.
Looking at ALT+F2 messages I noticed it mentionned a VG was already present on the system. I made me think that the first install on the SD Card maybe created it [as vgdisplay doesn't care about the physical drive and the SD card would be seen as sdb) and that the install script would be trying to use that already preconfigured VG. With the size problem that would maybe explain the issue.
I deactivated the SD cards so they would not be seen anymore and retried. There it goes PVE installs properly.
Conclusion: if
- an installation fails AFTER the VG/LV have been created
- [TBC] At least one of the errors is that the size of the drives was unsufficient
- you try to install again on another drive
- You may have to format or deactivate the previous drive to make sure PVE can install properly.
I though this may help future users trying to install on a similar configuration. As those servers are really new I am not sure yet if bigger SD cards are available. In terms of development maybe when an install fails the script should also attempt to undo all steps that impact the system and potentially new installs (but that is maybe too much to ask, I should have checked the size earlier in the process).
Have a nice day!
