Which linux has zfs

The mailing list and repository will also be removed shortly. ZFS, developed by Sun engineers, is the first 21st century file system. There are other issues with ZFS. The biggest is that it breaks the OSI 7-layer model.

The only file system that comes close is Btrfs, which has been often maligned as not being stable enough for production systems. ZFS may be the best-known enterprise-grade transactional file system to use storage pools to manage physical storage space. ZFS supports advanced file systems and can manage data long term whereas ext4 cannot.

ZFS is the best file system for data you care about, hands down. I also write a newsletter about the stuff that most history books miss. Check it out. I just went through a night mare with LVM2 shared from a Linux server to mac books.

It would not create the full size of the entire storage pool i. I installed ZFS and configuration was a snap, the entire 7TB was configure without a problem and performance surpasswd LVM2 by copying the same amount of data in just 10 minutes.

Hats of to the ZFS development team as the save my behind and lack of sleep as it is currently am. Nice article. Please log in again. The login page will open in a new tab. After logging in you can close it and return to this page. Why are People Crazy About it? Pooled storage in ZFS. Like what you read? Please share it with others. Thank you very much ZFS team Hats off. Tired Herb ;.

In As explained, having a ZFS on root option on our desktop was only a first step in what we want to achieve by adopting this combined file system and logical volume manager. I strongly suggest you read the 2 blog posts, linked above, as introductions to this blog series we are starting.

We then look at what ZSys , our dedicated helper for ZFS systems, can do for you and how you can interact with it. Finally, for the more tech savy, we deep dive into how we use ZFS, store properties and understand how the puzzle fits together.

We will give you tips on how to tweak it at your convenience if you are a ZFS sysadmin expert, while still keeping ZSys advanced capabilities compatible. The installer highlights this in the corresponding screen. We hope to be able to drop this experimental support in the coming cycle, and backport to a We updated from As usual, those releases 0.

We also backported in Ubuntu ZSys and other components for instance ZFS bindings have been updated to work with the new libzfs version. Thanks to this, we are committed to deliver the best OpenZFS on Linux experience to our audience by continuing to fix any important issues that arise, and backporting any critical fixes from newer releases. The installer experience has been reworked to be clearer and to offer more focused options for the user.

The real function of an LGPL kernel module shim isn't to sanction touching the kernel with non-GPL code, it's to protect the proprietary code on the far side of the shim from being forcibly published in the event of a GPL enforcement lawsuit victory. So far, so good, but then Torvalds dips into his own impressions of ZFS itself, both as a project and a filesystem.

It's that simple. It was always more of a buzzword than anything else, I feel And as far as I can tell, it has no real maintenance behind it any more There's only one other widely available filesystem that even takes a respectable stab at providing most of those features, and that's btrfs—which was not available for the first several years of ZFS' general availability.

In fact, btrfs still isn't really stable enough for production use, unless you nerf all the features that make it interesting in the first place. ZFS' per-block checksumming and automatic data repair has prevented data loss in my own real-world use many times, including this particularly egregious case of a SATA controller gone rabid.

A standard RAID1 mirror would have cheerfully returned that GB of bad data with no warning whatsoever, but ZFS' live checksumming and error detection mitigated the whole thing to the point of never having to so much as touch a backup.
