so I don't think a hard error would be possible always (it could prevent migrating VMs that have enough space in destination although not being evident...

Adding a check of [current VM size] vs [remaining space on target dataset] would be helpful, and a good way to avoid shooting yourself in the foot (which proxmox usually does pretty well). There could be a warning when the target dataset will be almost entirely filled (>97% usage), and an error when the target dataset isn't big enough to migrate the VM. > > I'm sorry if this is not the correct place to report this, but I didn't see any "feature request" subforum on the proxmox forum. > > Regards, > > Guillaume Vandenhove > > > > _______________________________________________ > pve-user mailing list > pve-user@lists.proxmox.com > https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user > Eneko Lacunza Zuzendari teknikoa | Director técnico Binovo IT Human Project Tel. +34 943 569 206 | https://www.binovo.es Astigarragako Bidea, 2 - 2º izda.
