[PVE-User] Proxmox and DRBD

[Klaus Darilion]

Hi!

Reading the archives I learnt that Proxmox removed DRBD as the 
consequence of license issues (which were reverted). As far as is know 
this was about DRBD9 and older Proxmox releases had support for DRBD8.

Checking the Proxmox sources (storage modules) it seems that there is 
still some code for DRBD left, but apperently not used.

IMO it is a real pitty that DRBD is not supported anymore. There are 
several use case where DRBD is a perfect and cost efficient solution 
avoiding additional external storages. Debian 9 comes with DRBD8 out of 
the - so why not use it (without needed any additonal software from Linbit)?

Is there any technical reason why DRBD(8) is not supported anymore?

Is it possible to activate and use the leftover DRBD code in Proxmox?

If not, I think the simple "manual" solution would be a DRBD-backed LVM 
storage in active-active mode. Any experiences with such a setup (except 
that it is not nice to have a single DRBD ressource for all VMs instead 
of one DRBD ressource per virtual disk)?

Thanks
