I understand. However, the created volumes should use a total=
of 1211GB. That's not 1.6TB like zfs list says. But 1211 + 431 (referre=
d) does come close to 1.6TB.n And 1.6 TB still isn't the 1.77TB that's i=
n the zpool.
I have this feeling that zfs has reserved the spac=
e for each volume, but counts data written to the volumes in usage of th=
e main filesystem. Mainly because zfs list shows me that the volumes hav=
e only 16KB referenced, where /storage has 431GB referenced.
