• Decrease size of the ZFS file system after installation


    Hi,
    How do I resize my partition zfs? I just installed Antergos on my machine, I used the option to erase the disk completely, but would like to decrease the size of the partition and use the space for other things. Research lead me to solutions for freebsd or solar systems. In several comments say it would be possible through the gpart command. already tested, but the options are not the same, not even in the manual there is a reference to the zfs.

  • The available space was limited internally, externally size remained the same. Decreases from 500GB to 170GB, but fdisk also tells me that I do not have free space to create another partition.

    $ sudo zfs set quota=170g antergos_vu1o/home

    $ sudo zfs list
    NAME USED AVAIL REFER MOUNTPOINT
    antergos_vu1o 8.42G 441G 6.36G /mnt
    antergos_vu1o/home 140K 170G 140K /mnt/home
    antergos_vu1o/swap 2.06G 443G 72K -

    $ sudo zfs set quota=170g antergos_vu1o

    $ sudo zfs list
