I've taken a quick look at this, and got a bit more with: ><rescue> ln -s ../run/lock /var/lock ><rescue> zfs-fuse-helper start Starting zfs-fuse: [ OK ] Immunizing zfs-fuse against OOM kills[ OK ] Mounting zfs partitions: [ OK ] and after this the zpool/zfs commands were usable. Just note that: a) the first command is not needed now with the newly released development version libguestfs 1.25.33 b) I couldn't mount the image you provided, since it was created with versions of zpool and zfs greater than what zfs-fuse currently supports (it seems not having been updated in a while...) so even if we automate somehow the starting of the zfs-fuse helper and the handling of zpool/zfs, I'm not sure it could be actually useful with a zfs-fuse not supporting recent versions. (To have a test partition with ZFS, I had to create it on a Debian/kFreeBSD 6.0 (oldstable), as even Debian/kFreeBSD 7 (stable) had "too new" zfs stuff for zfs-fuse.) -- Pino Toscano _______________________________________________ Libguestfs mailing list Libguestfs@redhat.com https://www.redhat.com/mailman/listinfo/libguestfs
