Hi all, I'm configuring Amanda over ZFS, with plans for a five 'tape' diskless cycle. When I'm calculating the size of each 'tape', should I divide up my dedicated backup space based on a 'df -h', or a 'zpool list'? Assume that if I go by the 'zpool list' command, I'd like to allocate 1.8TB, divided by five to tapes. Should I use this number, or would it be more appropriate to slice up the space based on the 'df -h' below? I'm assuming the latter, but I'd just like to ask for clarification. amanda# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT storage 1.82T 2.86G 1.82T 0% ONLINE - amanda# df -h Filesystem Size Used Avail Capacity Mounted on storage 1.3T 2.1G 1.3T 0% / devfs 1.0K 1.0K 0B 100% /dev Regards, Steve
