filesystem 'tank/volume' cannot be mounted, unable to open the dataset

za flag

I'm running ZFS and after zfs clone of a snapshot, I tried to mount the volume with command

mount -t zfs tank/volume /mnt

, but got an error message:

filesystem 'tank/volume' cannot be mounted, unable to open the dataset

How to fix this?

The problem is caused by the volume running ext4 and not zfs. Try just plain mount without the filesystem type defined, and use /dev/zvol/ as path, then mount uses filesystem type autodetection:

mount /dev/zvol/tank/volume /mnt

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
