In fairness though, with spare capacity, not reaching it's capacity, Btrfs has been rock solid for several years now.
Might check this again with the test server, time constraints, mean you never get to fully test stuff. But the raid remained healthy, on checking it. Before choosing Btrfs, we had a test server set up using small 5 x 250GB drives, and pulled drives, to simulate failed disks, implementing a rebuild to get a good understanding of issues and time to rebuild etc.Įven though we did test a raid array to near capacity, the main thing I remember is the transfers stopping before the limit was reached, and you'd lose access to the server over the network, based on notifications that 3% storage remained, then it would come back. Guessing from what you said, the array crashed went into read only mode. Thanks for the heads up on Btrfs, I'm looking at a Raid 5 device that is near its limit right now, though 10% not 3%. But, lawsuits by Oracle are not going to be a problem.
#Openzfs draid software#
So, yes, if you only want to use GPL software then OpenZFS might be a problem because it's CDDL licensed instead. They are obviously not going to sue either.
#Openzfs draid code#
Modern OpenZFS contains new code contributions from Nexenta Systems, Delphix, Intel, iXsystems, Datto and a whole bunch of other companies that have voluntarily offered their code when practically all of the non-Oracle ZFS implementations merged to become OpenZFS 2.0.
That's is why the majority of the code in OpenZFS 2 is from long after the various forks. The various ZFS implementations all developed their own support for TRIM, or Sequential Resilvering, or Zstd compression, or Persistent L2ARC, or Native ZFS Encryption, or Fusion Pools, or Allocation Classes, or dRAID long after 2005. A lot of storage tech, or even entire storage concepts, did not exist when SUN open sourced ZFS. Oracle have created their own closed source version of ZFS but outside some Oracle shops nobody uses it (and Oracle is rumoured to have stopped working on ZFS all together some time ago).Ĭonsidering the forks (first from SUN to the various open source implementations and later the fork from open source into Oracle's closed source version) were such a long time ago, there is not that much original code left. The question is, sue about what? The original ZFS was code open sourced before Oracle bought SUN.
If Oracle had the ability to sue, they would have done that years ago (knowing how litigious they are). The Lawrence Livermore National Laboratory uses OpenZFS on Linux to store their unfathomably large data sets. Entire enterprise storage product lines have been based on ZFS. ZFS is technically, economically and legally mature and has been in use by giants with deep pockets in the enterprise storage space for years. The suggestions of potential lawsuit around the use of ZFS have been a giant red herring (pun not intended) for years now.
