Hi folks, I've followed fearedbliss' guide for installing Gentoo on ZFS [1] and am trying to understand why /dev/zol/rpool/swap does not show up on reboot even though I saw it initially when creating the zvol and can still see it with zfs list:
xm2 ~ # zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 29.1G 176G 96K none rpool/HOME 4.98G 176G 4.98G /home rpool/ROOT 7.10G 176G 96K none rpool/ROOT/gentoo 7.10G 176G 7.10G / rpool/swap 17.0G 193G 354M - xm2 ~ # ls /dev/zvol ls: cannot access '/dev/zvol': No such file or directory xm2 ~ # I'm actually surprised my system boots at all, because /etc/fstab looks for that partition to be the swap: xm2 ~ # grep ^/dev /etc/fstab /dev/zvol/rpool/swap none swap sw,discard 0 0 xm2 ~ # My best guesses at the problem are either that it's udev related or that the various ZFS services need to be better configured to expose the zvol. I read the "Admin Documentation" links on the zfsonlinux.org website looking for mentions on "zvol" and the only relevant section seems to be the `zpool import` should apply `zfs share -a` to zvols [2]. Maybe I need to run `zfs share`? But that doesn't seem to help: xm2 ~ # zfs share rpool/swap cannot open 'rpool/swap': operation not applicable to datasets of this type xm2 ~ # zfs share -a xm2 ~ # ls /dev/zvol ls: cannot access '/dev/zvol': No such file or directory xm2 ~ # I haven't posted on this list in many years, so go easy on me :) Pariksheet [1] https://wiki.gentoo.org/wiki/User:Fearedbliss/Installing_Gentoo_Linux_On_ZFS#Create_your_swap_zvol [2] http://open-zfs.org/wiki/System_Administration#Boot_process
