I think Proxmox UI is showing the % of wearout consumed. I just checked = SMART using smartctl and it is showing 2.86 TB witten of a maximum of 18= 0 TBW of this model (6%). I think those numbers are too much for the usage of this drive, but the = number of power on hours match (52 days). I think the TBW are elevated b= ecause we had an instance with swap actived and that could generate s lo= t of IO (that's no longer the case from a couple of weeks ago). However, the strange behaviour of showing much more space used than the = sum of VM disks + snapshots continue, and I'm really worried that the pe= rformance issue after copying some data can come from that situation. Al= so, the unit is showing now a 96% of space used, which worries me about = decreased performance because of fragmentation issues.
