Samba 4.15 Released With Improved CLI Experience, Modernized VFS Interface

While there is now KSMBD with Linux 5.15 for offering an in-kernel SMB file server, its scope is much more limited than that of the Samba project in user-space. With that said, Samba 4.15 is out now with its latest batch of features and improvements for open-source SMB/CIFS support on Linux and other platforms.

OpenZFS 2.1.1 Arrives As A Big Point Release

Following the big OpenZFS 2.1 release from July that brought Distributed SPARE RAID, a compatibility property for pools, and other new features, OpenZFS 2.1.1 is available today as a follow-up release for this open-source ZFS file-system implementation for Linux and FreeBSD systems.

F2FS Sees More Performance Work For Linux 5.15

With Linux 5.15 there are optimizations for EXT4, big improvements for XFS, and significant work on Btrfs too. Rounding out the notable file-system work on Linux 5.15, the F2FS updates were submitted and subsequently landed for this next kernel version.

Samsung 860/870 SSDs Continue Causing Problems For Linux Users

While Samsung has explicitly stated before that queued TRIM works for Samsung 860 SSDs on Linux and thus leading to only older Samsung 840/850 drives being blocked from queued TRIM usage, that turns out to be inaccurate and now more quirks are added for the Samsung 860 and 870 series SSDs on Linux.

KSMBD As An In-Kernel SMB3 File Server Merged For Linux 5.15

One of the earliest pull requests sent in for the now-open Linux 5.15 cycle was proposing KSMBD land as the in-kernel SMB3 file server as an alternative on Linux systems to running Samba in user-space. At the time it wasn't clear if Linus Torvalds would pull in this file server code to the Linux kernel but now he has indeed landed it.

Linux 5.14 SSD Benchmarks With Btrfs vs. EXT4 vs. F2FS vs. XFS

A number of Phoronix readers have been asking about some fresh file-system comparisons on recent kernels. With not having the time to conduct the usual kernel version vs. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4, F2FS, and XFS file-system benchmarks on a speedy WD_BLACK SN850 NVMe solid-state drive.

HSE 2.0 Open-Source Storage Engine Is On The Way From Micron

Announced back in April of 2020 was Micron's HSE as an open-source storage engine optimized for solid-state drives and persistent memory. After quickly crossing the v1.0 milestone and working its way up to HSE 1.9 at the end of last year, there hasn't been any updates since. Fortunately, the project is still alive and HSE 2.0 is on the way.

Btrfs Set To Land Support For IDMAPPED Mounts In Linux 5.15

Introduced to the Linux kernel earlier this year with Linux 5.12 was IDMAPPED mounts that allow for different mounts to expose the same file or directory with different ownership. IDMAPPED mounts was designed with use-cases ranging from containers to systemd-homed and more as outlined in the earlier article. Btrfs is now ready to begin supporting IDMAPPED mounts.

Paragon's NTFS Driver For The Linux Kernel Spun Up A 27th Time

Those having to deal with data stored on NTFS partitions from Linux have been eagerly awaiting the "NTFS3" kernel driver that Paragon Software has been working now for a year to upstream into the Linux kernel. No pull request has been sent in yet but the twenty-seventh spin of this driver was published today.

Systemd/Microsoft Effort For A Global Counter On Block/Disk Changes Coming To Linux 5.15

Last month I wrote about a possible global counter for block/disk changes on Linux being discussed by Microsoft and systemd developers to better track changes via a system-wide monotonically increasing number as an alternative to the existing per-disk tracking. That functionality is now queued up as part of the block subsystem changes ahead of the Linux 5.15 merge window in a few weeks.

Micron Working On NVMe SSD Abrupt Shutdown Support For Linux

The NVMe specification provides for an abrupt shutdown mode over the normal/safe shutdown command if needing to quickly get the NVMe solid-state storage ready for powering off as quickly as possible. Currently the Linux kernel isn't making use of the NVMe abrupt shutdown command but a proposal by Micron is looking to begin its usage.

SquashFS Tools 4.5 Released To Celebrate 20 Years Of SquashFS

While SquashFS wasn't mainlined in the Linux kernel until 2009, this compressed read-only file-system has been in development for twenty years now with initially being a set of out-of-tree kernel patches. SquashFS has been instrumental to many Linux distributions for their Live DVD/USB environments and other use-cases where needing a general purpose read-only file-system with low overhead.

Linus Torvalds Calls On Paragon To Send In The New NTFS Driver

One year ago was the surprise of Paragon Software wanting to mainline their NTFS Linux kernel driver. The Paragon "NTFS3" kernel driver provides much better read/write support for Microsoft's NTFS file-system than what is available with other kernel or FUSE options for this file-system support on Linux. It looks like this driver might finally be mainlined soon.

Linux 5.14 Works Around Compatibility With Some Digital Camera exFAT File-Systems

Merged back in Linux 5.4 in late 2019 was the exFAT file-system driver that has proven to be quite mature at this stage with the work led by Samsung under the blessing of Microsoft. There hasn't been much in the way of exFAT file-system driver changes in recent kernel releases given its maturity. Even with Linux 5.14 there are just two exFAT patches but end up being notable at least for some users due to fixing file-system compatibility with some digital cameras.
