" Hello all im having an issue with ZFS and proxmox, for some reason it is reporting that im using X amount of data on side but different on another. Here is the zfs list -r data Code: zfs list -r data NAME USED AVAIL REFER MOUNTPOINT data 2.45T 100G 140K /data data/backup 5.73G 100G 5.73G /data/backup data/data 2.45T 100G 45.0M /data/data data/data/subvol-103-disk-1 2.45T 100G 104G /data/data/subvol-103-disk-1 data/iso 2.14G 100G 2.14G /data/iso and here is my df -h Code: df -h Filesystem Size Used Avail Use% Mounted on udev 7.8G 0 7.8G 0% /dev tmpfs 1.6G 109M 1.5G 7% /run rpool/ROOT/pve-1 85G 1.5G 84G 2% / tmpfs 7.8G 46M 7.8G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 7.8G 0 7.8G 0% /sys/fs/cgroup data 100G 256K 100G 1% /data data/backup 106G 5.8G 100G 6% /data/backup data/data 101G 45M 100G 1% /data/data data/data/subvol-103-disk-1 205G 105G 100G 52% /data/data/subvol-103-disk-1 data/iso 103G 2.2G 100G 3% /data/iso rpool 84G 128K 84G 1% /rpool rpool/ROOT 84G 128K 84G 1% /rpool/ROOT rpool/data 84G 128K 84G 1% /rpool/data rpool/data/subvol-100-disk-1 64G 4.5G 60G 7% /rpool/data/subvol-100-disk-1 rpool/data/subvol-101-disk-1 8.0G 1.1G 7.0G 14% /rpool/data/subvol-101-disk-1 rpool/data/subvol-102-disk-1 16G 1.6G 15G 10% /rpool/data/subvol-102-disk-1 rpool/data/subvol-103-disk-1 16G 1.5G 15G 10% /rpool/data/subvol-103-disk-1 /dev/fuse 30M 32K 30M 1% /etc/pve tmpfs 1.6G 0 1.6G 0% /run/user/0 tmpfs 1.6G 0 1.6G 0% /run/user/1000 As you can see in zfs list -r data, we see "data/data/subvol-103-disk-1 2.45T 100G 104G /data/data/subvol-103-disk-1" says using 2.45T but when i run df -f it says that data/data/subvol-103-disk-1 its only using 105GB. Also my VM only sees this 205GB mount instead of the 2.45T
Hi, df use for calculation fixed block size, but zfs has dynamic blocks. Also, df do not know dedub, compression, snapshots and all other zfs features.
