I have installed a NAS4Free on a VM, and as recommended, i installed it on a 1GB virtual disk, and assigned another disk 500GB to this VM for file storage.

I have created the disk, encrypted it, created a ZFS virtual disk, and then a ZFS storage pool. Everything was working. On every restart of this VM i needed to go on and mount the encrypted drive.

Recently i upgraded the host machine, and now i cant mount or make it work. I have tried removing everything and setting up from scratch everything, with the exception of formating the disk, i have used an encrypted one without formating it.

Does anybody have any suggestion on how can i at least get back my data, can i mount somehow the encrypted drive even in another utility, just need to get back the data that were on it.
