Proxmox 7.4 - unable to create data thin-pool

[0chi0]

Hi,
trying to install Proxmox 7.4-1.

at the "target harddisk" stage, I choose swapsize 128 and maxroot 100. I do it on ext4, I don't reduce the hdsize value by 228 (GB). after starting the installation itself - after the "create patition" step, then "create lv-s" - an error pops up unable to create data thin-pool. when I run the installer again, it won't change these values - the installer goes through fine. sha256 sum is correct. I run it on another flash drive - same thing. raid 5, element size 64KB, 11x 2TB

 

[noel.]

Selected chunk size 64.00Kib cannot address more then 15.82 TiB of thin pool data space. makes me think your element size is too small, I am assuming it would work with 512KiB.

I am no RAID expert, fyi, but wouldn't it make sense to use RAID 6 [1] or nested RAID [2] for extra redundancy?

Hope this helps.

PS: why is your swap so huge?
