Hi, to solve this one (for the archives maybe): root@vm:~ # zpool import -N newpool root@vm:~ # zfs set mountpoint=/ newpool/ROOT/default zfs set mountpoint=none newpool/ROOT zfs set mountpoint=/tmp newpool/tmp zfs set mountpoint=/usr newpool/usr zfs set mountpoint=/var newpool/var reboot Machine now starts like a charm with the new pool. Amazing. Thanks for all your help guys, this is very much appreciated.

When trying to set the mount point for the / file system, I am getting strange errors: > > root@vm:~ # zfs set mountpoint=none newpool/ROOT > cannot open 'newpool/ROOT': dataset does not exist > root@vm:~ # zpool import -c /tmp/newpool.cache -R /mnt newpool > root@vm:~ # zfs set mountpoint=none newpool/ROOT > cannot unmount '/mnt': Device busy > root@vm:~ # zfs set mountpoint=/ newpool/ROOT/default > cannot unmount '/mnt': Device busy > root@vm:~ # zfs set mountpoint=/tmp newpool/tmp > root@vm:~ # zfs set mountpoint=/usr newpool/usr > root@vm:~ # zfs set mountpoint=/var newpool/var > root@vm:~ # zfs set mountpoint=none newpool/ROOT > cannot unmount '/mnt': Device busy > root@vm:~ # zpool export newpool > root@vm:~ # zfs set mountpoint=none newpool/ROOT > cannot open 'newpool/ROOT': dataset does not exist > > So basically, when the pool is not mounted the system says „dataset does not exist“ but when I mount it and try to change the mount point it comes back with „Device busy“. Any ideas on how I am supposed to set the mount point for the root file system (first & last line of the commands listed above)? > > Many thanks. > > Kind regards > Sebastian > >> Am 02.05.2016 um 23:45 schrieb Matthias Fechner <idefix@fechner.net>: >> >> Am 02.05.2016 um 22:42 schrieb Sebastian Wolfgarten: >>> root@vm:~ # zfs list >>> NAME USED AVAIL REFER MOUNTPOINT >>> newpool 385M 5.41G 19K /mnt/zroot >>> newpool/ROOT 385M 5.41G 19K /mnt >>> newpool/ROOT/default 385M 5.41G 385M /mnt >>> newpool/tmp 21K 5.41G 21K /mnt/tmp >>> newpool/usr 76K 5.41G 19K /mnt/usr >>> newpool/usr/home 19K 5.41G 19K /mnt/usr/home >>> newpool/usr/ports 19K 5.41G 19K /mnt/usr/ports >>> newpool/usr/src 19K 5.41G 19K /mnt/usr/src >>> newpool/var 139K 5.41G 19K /mnt/var >>> newpool/var/audit 19K 5.41G 19K /mnt/var/audit >>> newpool/var/crash 19K 5.41G 19K /mnt/var/crash >>> newpool/var/log 44K 5.41G 44K /mnt/var/log >>> newpool/var/mail 19K 5.41G 19K /mnt/var/mail >>> newpool/var/tmp 19K 5.41G 19K /mnt/var/tmp >>> zroot 524M 26.4G 96K /zroot >>> zroot/ROOT 522M 26.4G 96K none >>> zroot/ROOT/default 522M 26.4G 522M / >>> zroot/tmp 74.5K 26.4G 74.5K /tmp >>> zroot/usr 384K 26.4G 96K /usr >>> zroot/usr/home 96K 26.4G 96K /usr/home >>> zroot/usr/ports 96K 26.4G 96K /usr/ports >>> zroot/usr/src 96K 26.4G 96K /usr/src >>> zroot/var 580K 26.4G 96K /var >>> zroot/var/audit 96K 26.4G 96K /var/audit >>> zroot/var/crash 96K 26.4G 96K /var/crash >>> zroot/var/log 103K 26.4G 103K /var/log >>> zroot/var/mail 96K 26.4G 96K /var/mail >>> zroot/var/tmp 92.5K 26.4G 92.5K /var/tmp >>> >>> I am assuming I have to amend the zfs parameters for the mount points but I can’t seem to figure out what’s wrong.
