OpenZFS/ZFS on Linux Releases Versions 2.2.2 and 2.1.14, Addressing Critical Data Corruption Issue

OpenZFS has released versions 2.2.2 and 2.1.14 to address a critical data corruption issue.

The bug, which was discovered due to changes in cp in coreutils 9.x, could cause data corruption due to an incorrect dirty dnode check. While it is unlikely that the bug was encountered on EL7, EL8, or EL9 when running cp, it is still recommended that users upgrade to either version 2.2.2 or 2.1.14 to ensure the fix is applied.

In addition to the data corruption fix, the release includes several other bug fixes and improvements. These include fixing ZFS so that snapshots under .zfs/snapshot are NFS visible on FreeBSD, addressing compatibility issues with Linux 6.6, and fixing build and shell-init errors on FreeBSD.

For a full list of changes and bug fixes, refer to the release notes.

OpenZFS Continues to Grapple with Data Corruption Challenges

Last week saw the release of OpenZFS 2.2.1, which was initially believed to have fixed a data corruption issue attributed to a block cloning bug in a new feature introduced in the v2.2 release. However, further investigation over the US holiday weekend revealed that the block cloning feature was not the root cause, and both v2.2.1 and pre-v2.2 releases remain susceptible to data corruption.

It has been discovered that the data corruption bug affects not only the v2.2 release but also older versions of OpenZFS. While real-world instances of data corruption are believed to be limited, scripting can reproduce the issue. Additionally, it is now understood that the OpenZFS 2.2 block cloning feature increases the likelihood of encountering the problem.

The FreeBSD project has issued an advisory regarding the OpenZFS data corruption issue and recommends a workaround involving setting sysctl vfs.zfs.dmu_offset_next_sync=0 to “drastically reduce the likelihood” of experiencing the problem.

A pending pull request on GitHub is anticipated to address the OpenZFS data corruption issue. Hopefully, a new OpenZFS point release will be available soon, effectively resolving the data corruption problem.

AOOSTAR Unveils Powerful NAS with 6 HDD, 6 NVMe, Ryzen 7 5800U Processor

AOOSTAR, a Chinese PC maker known for its attractively-priced hardware, has announced that it is developing a powerful and versatile network attached storage (NAS) system set to launch early next year. The upcoming NAS will be a compact computer powered by an AMD Ryzen 7 5800U processor, featuring 8 Zen 3 CPU cores and Radeon Vega graphics, offering the performance of a decent 2021-era laptop.

What sets this NAS apart is its impressive specifications:

The upcoming AOOSTAR NAS is reminiscent of the ZimaCube Pro, with its similar shape and support for up to 6 SATA connectors for 2.5 inch or 3.5 inch hard drives, as well as multiple Ethernet ports. However, the ZimaCube Pro features an Core i5-1235U processor, Thunderbolt 4 ports, and a total of four Ethernet ports. The retail price for the ZimaCube Pro is expected to be $1,199, while AOOSTAR’s NAS is expected to have a lower price tag due to the company’s focus on budget computers.

AOOSTAR does not provide software with its NAS; customers are expected to provide their own software. However, there are several compatible options, such as TrueNAS, OpenMediaVault, Unraid, or even building a CasaOS system by installing Ubuntu, Debian, or CentOS and then loading the CasaOS user interface.

While AOOSTAR’s NAS systems offer competitive pricing, some users may prefer more well-known brands like Synology or QNAP for a hassle-free experience. However, for those who have the time and interest in configuring a DIY solution, AOOSTAR’s NAS systems provide powerful features and customization options.

More details about AOOSTAR’s upcoming 6-bay NAS will be available closer to its launch.
