Subject: [PVE-User] ZFS Disk Usage unexpected high
Date: Mon, 05 Apr 2021 10:22:56 +0200 [thread overview]
Message-ID: <7e9d1358dcb12b288e884547553e39b4@konsec.com> (raw)
Hi,
I set up a single VM which currently used 15TB of data.
/dev/sdb is technically a ZFS volume on the Proxmox Host.
[root@vm ~]# df -h /data
Filesystem Size Used Avail Use% Mounted on
/dev/sdb 40T 15T 25T 37% /data
[root@vm ~]# du -s /data/
14874345100 /data/
[root@host /]# zfs list zfs01/PVE-BE/vm-1-disk-1
NAME USED AVAIL REFER MOUNTPOINT
zfs01/PVE-BE/vm-1-disk-1 31.5T 5.82T 31.5T -
Why is the usage on the host about twice as large as within the vm?
(Yes, I have given fstrim and discard a try).
