The host is a special system based on Linux und VirtualBox and I have no chances to configure the VBox. Somehow the VBox crashed and hung up the complete computer, so I had to cold start it after approx. 30 minutes of waiting. After that, rhe virtual drive and its ZFS filesystem was wrecked, shwing a stream of zio_read error: 5 ZFS: i/o error - all block copies unavailable After a quick search I found some advices howto try fixing, last an longest one was zpool import -fFX -N -R /alternate/path zroot which took approx 20 minutes - with no success. There are some valuable data on the partition, which are all backed up, but it would take its time to restore everything, so I'd like to ask whether there is any cance to "repair" the mysterious damage. I'm able to boot off from an USB flash drive ... Kind regards oh -- O. Hartmann
