Re: [PVE-User] Proxmox and ZFS on large JBOD ?

[Adam Thompson <athompso@athompso.net>]

For additional clarity, I meant TrueNAS CORE, which is still based on FreeBSD and is still free as in beer.
TrueNAS SCALE is Linux-based, as another commenter mentioned, but also optimized for large storage... and is also free?
SCALE is the future direction, I think, while CORE is the tried and true, mature product but is now sort of deprecated?  iX's messaging and branding isn't very clear on this.
Either should work for you, AFAICT, a lot better than trying to use Proxmox as a NAS.
FWIW, I have used TrueNAS CORE in the past (when it was still called FreeNAS) as the NFS server *for* a Proxmox install, and it was solid.

IMHO, you want TrueNAS, not Proxmox, to solve this problem.

Ultimately, the problem is SystemD's notion of dependencies and timeouts, which Proxmox+OpenZFS still relies on.

Source: I have a Debian 10 system with 29 storage devices, 24 of which are multipathed, and have had to edit & override various systemd settings to get it to boot cleanly, reliably.

Hi pve-users !

Does anybody has experiences if proxmox works
flawlessly to manage a large zfs volume consisting
of a SAS-connected  JBOD of 60 * 1TB-HDDs ?

Right now, management is done with a regular
Debian 11 installation, and rebooting the thing
always ends up in a timeout mess at network startup,
because it takes ages to enumerate all those member disks,
import the zpool and export it via NFS.

I am considering to install Proxmox on this server for the
sole purpose of smooth startup and management operation.
Might that be a stable solution ?

Best regards,
Martin
