Linux 6.2 的 Btrfs 改進

Linux 6.2 的 Btrfs 改進

在 Hacker News 上看到 Btrfs 的改善消息：「Btrfs With Linux 6.2 Bringing Performance Improvements, Better RAID 5/6 Reliability」，對應的討論在「 Btrfs in Linux 6.2 brings performance improvements, better RAID 5/6 reliability (phoronix.com)」這邊。 因為 ext4 本身很成熟了，加上特殊的需求反而會去用 OpenZFS，就很久沒關注 Btrfs 了，這次看到 Btrfs 在 Linux 6.2 上的改進剛好可以重顧一下情況。 看起來是針對 RAID 模式下的改善，包括穩定性與效能，不過看起來是針對 RAID5 的部份多一點。 就目前的「情勢」看起來，Btrfs…

Forgot to add this the first time

Normalize creating your own private household cloud storage network instead of renting a hard drive from a corporation

Folks, WASDkeyboards got stock! Got one for my personal workstation. Obligatory OpenZFS key and WASD to match the Ubuntu orange (also the super key).

OpenZFS 2.0 será lançado em 2020 com suporte unificado ao Linux e FreeBSD

OpenZFS 2.0 será lançado em 2020 com suporte unificado ao Linux e FreeBSD

Na semana passada, em San Francisco, aconteceu a cúpula anual do desenvolvedor do OpenZFS. Como sempre, Matthew Ahrens, co-fundador do Sun ZFS e atual colaborador do OpenZFS na Delphix, falou sobre o trabalho em relação ao código aberto do ZFS em sua palestra. A grande novidade anunciada é que o OpenZFS 2.0 será lançado em 2020 com suporte unificado ao Linux e FreeBSD.

Virtualization platform Proxmox VE 6.4 changes to OpenZFS 2.0

Virtualization platform Proxmox VE 6.4 changes to OpenZFS 2.0

The new Proxmox VE 6.4 is based on Debian GNU / Linux 10.9 “Buster” with a Linux kernel 5.4 (LTS) or optionally 5.11. The HA-enabled virtualization solution manages both virtual machines and Linux containers via a clear WebGUI. The virtual machines provide a combination of QEMU 5.2 with KVM, whereby VMs can be linked to certain QEMU machine versions by “pinning”. Linux containers, provided by…

Setup openzfs on freebsd

Ongoing maintenance and monitoring can also be achieved from the command line or with the tools that you already have in place for maintaining your other FreeBSD systems. In practical terms, NAS configuration is mostly a one-time thing that is easy enough to perform from the command line. While some vendors offer customized hardware builds, if you already know what you want for hardware, you can build it yourself without adding the cost of a middleman to build it for you.Ĭonfiguring a NAS on top of your own FreeBSD installation also means that you don’t have the overhead of running a GUI, or learning where to perform the various configuration options from that GUI. Pre-built NAS solutions will only offer a small selection of hardware choices which may or may not meet your needs. Given that several FreeBSD-based NAS distributions are readily available, ranging from completely open source to pre-built with customer support plans, the question naturally arises: “why not just use a FreeBSD-based NAS distro rather than building your own”? After all, someone else has done the work to tune FreeBSD and most solutions provide a nice GUI for configuring the various NAS options. In this article we take a closer look at the operating system and the configurations, both during and after installation, to fine-tune the system for OpenZFS storage. We’re taking a build-up approach, where we first walk you through the hardware steps, and now we’re bringing up the next layer in our step-up – setting up your FreeBSD operating system. In the first article in this series, we concentrated on selecting suitable hardware for your FreeBSD and OpenZFS-based NAS.

Zpool send resume openzfs

Applications may be affected.Īction: Restore the file in question if possible. Status: One or more devices has experienced an error resulting in dataĬorruption. When I ran zpool status -v on my file server, I saw irrecoverable errors: The first noticeable problems involved videos cutting off midstream, following by I/O errors. In the end, ZFS saved me from what could have been disastrous amounts of data corruption due to faulty hardware. I took a long journey through ZFS bug reports, attempted to switch to Btrfs and even migrated my storage to a different computer. When I attempted to sync snapshots to the new device, I started to see I/O errors and kernel panics. My storage had outgrown my previous backup drive anyway, so I purchased an additional drive. I didn’t see any SMART errors on the drives, but still assumed that my hard drive could be going bad. Not soon after, I started getting random file corruption issues. Recently I upgraded from Alpine 3.12 to 3.14, which included a ZFS 0.8 to ZFS 2.0 update. I’ve been using ZFS for years on my Linux storage server. ZFS Woes, or how ZFS Saved Me From Data Corruption
