After creating the duplicate volume in the new pool and having tested that it works (it does) I exported the ZFS pool and it gives me the following errors: # zpool export nas1bkp cannot open 'nas1bkp/iscsi-cctvp3': dataset does not exist cannot open 'nas1bkp/iscsi-cctvp2': dataset does not exist cannot open 'nas1bkp/iscsi-cctvp1': dataset does not exist Its quite right, those datasets don't exist. But why is it even trying to touch something that doesn't and has never existed. Devices that actually exist are shown here: # zfs list NAME USED AVAIL REFER MOUNTPOINT nas1 3.19T 2.15T 648M /nas1 nas1/cctv 2.53M 2.15T 2.53M /nas1/cctv nas1/iscsi-cctv 3.19T 2.65T 2.65T - nas1/zfssend 28.4K 50.0G 28.4K /nas1/zfssend nas1bkp 3.19T 2.15T 28.4K /nas1bkp nas1bkp/iscsi-cctv 3.19T 2.65T 2.65T - nas1bkp/zfsrecv 26.9K 50.0G 26.9K /nas1bkp/zfsrecv Anyone any idea whats going on? Spurious errors make me nervous! thanks Andy.
