Making ZFS file systems available is similar to Oracle Solaris 10 releases in the following ways:
A ZFS file system is mounted automatically when it is created and then remounted automatically when the system is booted.
You do not have to modify the /etc/vfstab file to mount a ZFS file system, unless you create a legacy mount for ZFS file system. Mounting a ZFS file system automatically is recommended over using a legacy mount.
You do not have to modify the /etc/dfs/dfstab file to share file systems. See ZFS File System Sharing Changes.
Similar to a UFS root, the swap device must have an entry in the /etc/vfstab file.
File systems can be shared between Oracle Solaris 10 and Oracle Solaris 11 systems by using NFS sharing.
File systems can be shared between Oracle Solaris 11 systems by using NFS or SMB sharing.
You can export ZFS storage pools from an Oracle Solaris 10 system and then import them to an Oracle Solaris 11 system.
