How do I resume an interrupted ZFS send/receive on Debian/stretch via ZFS on Linux? It seems that the zfs send -t option isn't there.
How do I change the default options for zfs filesystems on an existing zpool?
That is, ZFS stored for each zpool pool the default values for new zfs filesystems. Those are then used by zfs create as default values if they aren't explicitly overwritten.
I know that zpool allows to set those default values on creation, by using the capital -O flag:
zpool create -O atime=off -O compression=on ...
That way, all filesystem creation commands can be shortened from:
zfs create -o atime=off -o compression=on ...
to:
zfs create ...
However, what if I didn't set the -O on zpool creation? How can I set or change them for an existing pool?
Update
The following command finally worked for me:
zfs set atime=off compression=on zroot
