The reason is that encrypted data has always high entropy making compression ineffective and even from the same input you get different output (thanks to salting) making deduplication impossible. ZFS will see the encrypted data, not the plain-text abstraction, so compression and deduplication will not work. To reduce the unnecessary overhead it is possible to create a sub-filesystem for each encrypted directory and use eCryptfs on it.

Gdisk does not automatically name partitions so if partition labels are desired use gdisk command “c” to label the partitions. Some reasons you might prefer labels over UUID are: labels are easy to control, labels can be titled to make the purpose of each disk in your arrangement readily apparent, and labels are shorter and easier to type. Use gdisk to partition the all or part of the drive as a single partition. GPT partition labels have plenty of space and can store most international characters wikipedia:GUID_Partition_Table#Partition_entries allowing large data pools to be labeled in an organized fashion. These are all advantages when the server is down and the heat is on.

This will import your pools using /dev/sd. This may be as simple as rebooting with a USB drive left in the machine, which harkens back to a time when PC’s would not boot when a floppy disk was left in a machine. Adapt one of the following commands to import your pool so that pool imports retain the persistence they were created with. Which will lead to problems the next time you rearrange your drives.

It worsens when you consider people are being insane with ZFS. Now the admin has to remove noatime from /etc/fstab and basically loses .
