\nBasic guide (may need improvments and it’s not failproof) to shrink zfs disks:
\n1. prepare your vm disk for shrinking and shut it down
\n2. in pve shell set new zfs pool size
\n\n\t\n\t\n\n\n\n\t\n\t\tCode:\n\t\n\t\n\t\t<\/p>\n\n\n
\n$zfs set volsize=<new size>G rpool\/data\/vm-<vm id>-disk-<disk number>\n<\/pre><\/div>\n\n\n\n\t\n3. edit vm config in \/etc\/pve\/local\/qemu-server\/<vm id><\/strong>.conf on line
\n\n\t\n\t\n\n\n\n\t\n\t\tCode:\n\t\n\t\n\t\t<\/p>\n\n\n\nvirtio0: local-zfs:vm-<vm id>-disk-<disk number>,size=<new size>G\n<\/pre><\/div>\n\n\n\n\t\nObviusly the line may not be the same, just edit the disk size
\n4. in pve panel change the cache mode to something else and then revert back, this should update the config
\nNote: you may corrupt your partition table, to fix it in linux boot on a recovery live image like gparted and launch gdisk
\n\n\t\n\t\n\n\n\n\t\n\t\tCode:\n\t\n\t\n\t\t<\/p>\n\n\n
\n$ gdisk \/dev\/vda\n<\/pre><\/div>\n\n\n\n\t\nand then press v,x,e,w and y.
\nThis should do the trick.\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
