[2] [3] It is built upon enterprise-tested components LVM and XFS with over a decade of enterprise deployments and the lessons learned from System Storage Manager in Red Hat Enterprise Linux 7. [ 4 ] Stratis provides ZFS/Btrfs-style features by integrating layers of existing technology: Linux's device mapper subsystem, and the XFS filesystem.
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
On most LVM setups, only one copy of the LVM head is saved to each PV, which can make the volumes more susceptible to failed disk sectors. This behavior can be overridden using vgconvert --pvmetadatacopies. If the LVM can not read a proper header using the first copy, it will check the end of the volume for a backup header.
NetBSD from version 6.0 supports its own re-implementation of Linux LVM. Re-implementation is based on a BSD licensed device-mapper driver and uses a port of Linux lvm tools as the userspace part of LVM. There is no need to support RAID5 in LVM because of NetBSD superior RAIDFrame subsystem. NetBSD: ZFS: Yes Yes Yes Yes Yes Yes Yes
Bcachefs describes itself as "working and stable, with a small community of users". [11] When discussing Linux 6.9-rc3 on April 7, 2024, Linus Torvalds touched on the stability of bcachefs, saying "if you thought bcachefs was stable already, I have a bridge to sell you ", [ 12 ] and in August of 2024 that "nobody sane uses bcachefs and expects ...
Lustre Cluster filesystem will use FUSE to allow it to run in userspace, so that a FreeBSD port is possible. [11] However, the ZFS-Linux port of Lustre will be running ZFS's DMU (Data Management Unit) in userspace. [12] MinFS: MinFS is a fuse driver for Amazon S3 compatible object storage server.
As the FSF (Free Software Foundation) claimed that there was a legal incompatibility between the CDDL and the GPL in 2005, Sun's implementation of the ZFS file system couldn't be used as a basis for the development of a module in the Linux kernel, couldn't be merged into the mainline Linux kernel, and Linux distributions generally did not include it as a precompiled kernel module.
EVMS had more features and better userland tools, but the internals of LVM were more attractive to kernel developers, so in the end LVM won the battle for inclusion. In response, the EVMS team decided to concentrate on porting the EVMS userland tools to work with the LVM kernelspace.
