I.e., two things - a comment that is displayed only and has no duplication checks and a relatively flexible format (maxLength 64 and /^[\S ]+/) saved as, e.g.,= URL-encoded. This is realtively easy to do, and someone already tried but went IMO way overboard and added comment fields for everything, which just does not makes sense for most options but disks and nics. - a alias, that is checked unique per VMID (via config) and is actually inside the volume name. This is a bit harder to get nicely right, especially if one wants to do queries on that information. Storage move's would need some handling for (non-recommended) sharing of storage between clusters, or just left-over volumes. Similar for disk-movements to other guests, but as the counter would stay it wouldn= 't be that hard. My question here is is duch a thing is really worth it, as having that encoded is one thing, but the user actually needs to have the foresight= to set the correct alias so that they have some value from it listing volumes at the storage-layer in the disaster case. And having the confi= g around, they could to that mapping too if they used comments. So, I'd not go for the alias/description/... in volume name for now, rather do the per-disk comment first, which is way simpler to maintain forever and provides not that less benefits, while being quite a bit less work.
