Check out the pvesr for storage replication. https://pve.proxmox.com/pve-docs/chapter-pvesr.html > > Is there any technical reason why DRBD(8) is not supported anymore? The storage plugin is, AFAIR only for DRBD9. https://docs.linbit.com/docs/users-guide-9.0/#ch-proxmox > > 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.

Try pvesr, as mentioned above, it uses ZFS and snapshots to replicate volumes, less hassle then with DRBD, IMHO. Or give Ceph a go, integrated into PVE. -- Cheers, Alwin _______________________________________________ pve-user mailing list [email protected] https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
