Aaron Toponce : ZFS Administration, Part II- RAIDZ
The previous post introduced readers to the concept of VDEVs with ZFS. This post continues the topic discusing the RAIDZ VDEVs in great detail. Standards Parity RAID To understand RAIDZ, you first need to understand parity-based RAID levels, such as RAID-5 and RAID-6. Let's discuss the standard RAID-5 layout. You need a minimum of 3 disks for a proper RAID-5 array. On two disks, the data is stripe
Linus Torvalds Doesn't Recommend Using ZFS On Linux - Phoronix
Linus Torvalds Doesn't Recommend Using ZFS On Linux Written by Michael Larabel in Linux Storage on 9 January 2020 at 04:49 PM EST. 255 Comments Linux kernel creator Linus Torvalds doesn't recommend using ZFS On Linux at least until Oracle were to re-license the code to make it friendly for mainline inclusion. But even then he doesn't seem turned on by the ZFS features or general performance. Derai

The ZFS filesystem has been a game-changer in the way we approach local application data storage, shared storage solutions, replication and general data backup. I've been a long-time proponent of ZFS storage in a variety of scenarios, going back to my first experiences with OpenSolaris in 2008, buying my own ZFS Thumper/Thor in 2009, adopting ZFS on Linux for production use in 2012, and through co

Aaron Toponce : Install ZFS on Debian GNU/Linux
UPDATE (May 06, 2012): I apologize for mentioning it supports encryption. Pool version 28 is the latest source that the Free Software community has. Encryption was not added until pool version 30. So, encryption is not supported natively with the ZFS on Linux project. However, you can use LUKS containers underneath, or you can use Ecryptfs for the entire filesystem, which would still give you all
