ZFS 10 drives in rpool installer possible

[mram]

Is there any way to install to a 10 drive ZFS RAIDZ2 from the installer? Right now the limit appears to be 8 drives.

I don't want separate pools nor do I want to lose half the drive space on vdev mirrors by adding the remaining drives after installation.

Yes, the current limit is 8 drives.

The only way I can come up with is to

• install on a smaller amount of disks
• boot a live linux with ZFS support
• snapsnot the system and send the installed filesystem to a file on a remote location
• recreate the pool with all devices and configure booting over all devices
• receive the installed Proxmox VE installation
• fix ZFS cache file, zpool stuff and grub
• reboot

and then you'll hopefully have a working Proxmox VE on 10 devices. You can "test" your environment from the live linux with Qemu.

Thanks for the idea. I will give it a try.
