Why not ZFS
ZFS is a hybrid filesystem and volume manager system that is quite popular recently but has some important and unexpected problems. It has many good features, which are probably why it is used: snapshots (with send/receive suppport), checksumming, RAID of some kind (with scrubbing support), deduplication, compression, and encryption. But ZFS also has a lot of downsides. It is not the only way to a
New – Amazon FSx for OpenZFS | Amazon Web Services
AWS News Blog New – Amazon FSx for OpenZFS Last month, my colleague Bill Vass said that we are “slowly adding additional file systems†to Amazon FSx. I’d question Bill’s definition of slow, given that his team has launched Amazon FSx for Lustre, Amazon FSx for Windows File Server, and Amazon FSx for NetApp ONTAP in less than three years. Amazon FSx for OpenZFS Today I am happy to announce Amazon F

FreeBSD ZFS File-System Code To Be Re-Based Over ZFS On Linux - Phoronix
FreeBSD ZFS File-System Code To Be Re-Based Over ZFS On Linux Written by Michael Larabel in BSD on 19 December 2018 at 08:55 AM EST. 22 Comments With ZFS On Linux (ZOL) being more actively developed than the ZFS file-system code within the OpenSolaris-derived Illumos kernel, FreeBSD will be transitioning their ZFS file-system kernel driver to be based on ZOL.

About ZFS Performance
If you are a regular reader of this blog, you likely know I like the ZFS filesystem a lot. ZFS has many very interesting features, but I am a bit tired of hearing negative statements on ZFS performance. It feels a bit like people are telling me “Why do you use InnoDB? I have read that MyISAM is faster.†I found the comparison of InnoDB vs. MyISAM quite interesting, and I’ll use it in this post. To
