tl;dr - I had an 8TB disk in proxmox that only had 2TB of data, wanting to free space, i used `zfs set volsize=5T` on that volume, after repairing the filesystem, only 1TB of data remains (mostly bitcoin node blockchain data and nostr.download data)
I will continue to attempt data recovery to restore those critically missing databases.
On a side note, are there any data recovery experts on nostr? #asknostr
