Causing ZFS corruption for fun, NetBSD Assembly Programming Tutorial, The IKEA Lack Rack for Servers, a new OmniOS Community Edition LTS has been published, List Block Devices on FreeBSD lsblk(8) Style, Project Trident 19.10 available, and more. Headlines Causing ZFS corruption for fun and profit Datto backs up data, a lot of it. At the time of writing Datto has over 500 PB of data stored on ZFS. This count includes both backup appliances that are sent to customer sites, as well as cloud storage servers that are used for secondary and tertiary backup of those appliances. At this scale drive swaps are a daily occurrence, and data corruption is inevitable. How we handle this corruption when it happens determines whether we truly lose data, or successfully restore from secondary backup. In this post we'll be showing you how at Datto we intentionally cause corruption in our testing environments, to ensure we're building software that can properly handle these scenarios. Causing Corruption Since this is a mirror setup, a naive solution to cause corruption would be to randomly dd the same sectors of both /dev/sdb and /dev/sdc. This works, but is equally likely to just overwrite random unused space, or take down the zpool entirely. What we really want is to corrupt a specific snapshot, or even a specific file in that snapshot, to simulate a more realistic minor corruption event. Luckily we have a tool called zdb that lets us view some low level information about datasets. Conclusion At the 500 PB scale, it's not a matter of if data corruption will happen but when. Intentionally causing corruption is one of the strategies we use to ensure we're building software that can handle these rare (but inevitable) events. To others out there using ZFS: I'm curious to hear how you've solved this problem. We did quite a bit of experimentation with zinject before going with this more brute force method. So I'd be especially interested if you've had luck simply simulating corruption with zinject. NetBSD Assembly Programming Tutorial A sparc64 version is also being prepared and will be added when done This post describes how to write a simple hello world program in pure assembly on NetBSD/amd64. We will not use (nor link against) libc, nor use gcc to compile it. I will be using GNU as (gas), and therefore the AT&T syntax instead of Intel. Why assembly? Why not? Because it's fun to program in assembly directly. Contrary to a popular belief assembly programs aren't always faster than what optimizing compilers produce. Nevertheless it's good to be able to read assembly, especially when debugging C programs Due to the nature of the guide, visit the site for the complete breakdown News Roundup The IKEA Lack Rack for Servers The LackRack First occurrence on eth0:2010 Winterlan, the LackRack is the ultimate, low-cost, high shininess solution for your modular datacenter-in-the-living-room. Featuring the LACK (side table) from Ikea, the LackRack is an easy-to-implement, exact-fit datacenter building block. It's a little known fact that we have seen Google engineers tinker with Lack tables since way back in 2009. The LackRack will certainly make its appearance again this summer at eth0:2010 Summer. Summary When temporarily not in use, multiple LackRacks can be stacked in a space-efficient way without disassembly, unlike competing 19" server racks. The LackRack was first seen on eth0:2010 Winterlan in the no-shoe Lounge area. Its low-cost and perfect fit are great for mounting up to 8 U of 19" hardware, such as switches (see below), or perhaps other 19" gear. It's very easy to assemble, and thanks to the design, they are stable enough to hold (for example) 19" switches and you can put your bottle of Club-Mate on top! Multi-shiny LackRack can also be painted to your specific preferences and the airflow is unprecedented! Howto You can find a howto on buying a LackRack on this page. This includes the proof that a 19" switch can indeed be placed in the LackRack in its natural habitat! OmniOS Community Edition r151030 LTS - Published at May 6, 2019 The OmniOS Community Edition Association is proud to announce the general availability of OmniOS - r151030. OmniOS is published according to a 6-month release cycle, r151030 LTS takes over from r151028, published in November 2018; and since it is a LTS release it also takes over from r151022. The r151030 LTS release will be supported for 3 Years. It is the first LTS release published by the OmniOS CE Association since taking over the reins from OmniTI in 2017. The next LTS release is scheduled for May 2021. The old stable r151026 release is now end-of-life. See the release schedule for further details. This is only a small selection of the new features, and bug fixes in the new release; review the release notes for full details. If you upgrade from r22 and want to see all new features added since then, make sure to also read the release notes for r24, r26 and r28. For full relase notes including upgrade instructions; release notes upgrade instructions List Block Devices on FreeBSD lsblk(8) Style When I have to work on Linux systems I usually miss many nice FreeBSD tools such as these for example to name the few: sockstat, gstat, top -b -o res, top -m io -o total, usbconfig, rcorder, beadm/bectl, idprio/rtprio,… but sometimes – which rarely happens – Linux has some very useful tool that is not available on FreeBSD. An example of such tool is lsblk(8) that does one thing and does it quite well – lists block devices and their contents. It has some problems like listing a disk that is entirely used under ZFS pool on which lsblk(8) displays two partitions instead of information about ZFS just being there – but we all know how much in some circles the CDDL licensed ZFS is unloved in that GPL world. Example lsblk(8) output from Linux system: $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 1024M 0 rom sda 8:0 0 931.5G 0 disk |-sda1 8:1 0 500M 0 part /boot `-sda2 8:2 0 931G 0 part |-vg_local-lv_root (dm-0) 253:0 0 50G 0 lvm / |-vg_local-lv_swap (dm-1) 253:1 0 17.7G 0 lvm [SWAP] `-vg_local-lv_home (dm-2) 253:2 0 1.8T 0 lvm /home sdc 8:32 0 232.9G 0 disk `-sdc1 8:33 0 232.9G 0 part `-md1 9:1 0 232.9G 0 raid10 /data sdd 8:48 0 232.9G 0 disk `-sdd1 8:49 0 232.9G 0 part `-md1 9:1 0 232.9G 0 raid10 /data What FreeBSD offers in this department?

DragonFlyBSD vs. FreeBSD vs. Linux benchmark on Ryzen 7, JFK Presidential Library chooses TrueNAS for digital archives, FreeBSD 12.1-beta is available, cool but obscure X11 tools, vBSDcon trip report, Project Trident 12-U7 is available, a couple new Unix artifacts, and more. Headlines DragonFlyBSD 5.6 vs. FreeBSD 12 vs. Linux - Ryzen 7 3700X For those wondering how well FreeBSD and DragonFlyBSD are handling AMD's new Ryzen 3000 series desktop processors, here are some benchmarks on a Ryzen 7 3700X with MSI MEG X570 GODLIKE where both of these popular BSD operating systems were working out-of-the-box. For some fun mid-week benchmarking, here are those results of FreeBSD 12.0 and DragonFlyBSD 5.6.2 up against openSUSE Tumbleweed and Ubuntu 19.04. Back in July I looked at FreeBSD 12 on the Ryzen 9 3900X but at that time at least DragonFlyBSD had troubles booting on that system. When trying out the Ryzen 7 3700X + MSI GODLIKE X570 motherboard on the latest BIOS, everything "just worked" without any compatibility issues for either of these BSDs. We've been eager to see how well DragonFlyBSD is performing on these new AMD Zen 2 CPUs with DragonFlyBSD lead developer Matthew Dillon having publicly expressed being impressed by the new AMD Ryzen 3000 series CPUs. For comparison to those BSDs, Ubuntu 19.04 and openSUSE Tumbleweed were tested on the same hardware in their out-of-the-box configurations. While Clear Linux is normally the fastest, on this system Clear's power management defaults had caused issues in being unable to detect the Samsung 970 EVO Plus NVMe SSD used for testing and so we left it out this round. All of the hardware was the same throughout testing as were the BIOS settings and running the Ryzen 7 3700X at stock speeds. (Any differences in the reported hardware for the system table just come down to differences in what is exposed by each OS for reporting.) All of the BSD/Linux benchmarks on this eight core / sixteen thread processor were run via the Phoronix Test Suite. In the case of FreeBSD 12.0, we benchmarked both with its default LLVM Clang 6.0 compiler as well as with GCC 9.1 so that it would match the GCC compiler being the default on the other operating systems under test. JFK Presidential Library Chooses iXsystems TrueNAS to Preserve Precious Digital Archives iXsystems is honored to have the TrueNAS® M-Series unified storage selected to store, serve, and protect the entire digital archive for the John F. Kennedy Library Foundation. This is in support of the collection at the John F. Kennedy Presidential Library and Museum (JFK Library). Over the next several years, the Foundation hopes to grow the digital collection from hundreds of terabytes today to cover much more of the Archives at the Kennedy Library. Overall there is a total of 25 million documents, audio recordings, photos, and videos once the project is complete. Having first deployed the TrueNAS M50-HA earlier in 2019, the JFK Library has now completed the migration of its existing digital collection and is now in the process of digitizing much of the rest of its vast collection. Not only is the catalog of material vast, it is also diverse, with files being copied to the storage system from a variety of sources in numerous file types. To achieve this ambitious goal, the library required a high-end NAS system capable of sharing with a variety of systems throughout the digitization process. The digital archive will be served from the TrueNAS M50 and made available to both in-person and online visitors. With precious material and information comes robust demands. The highly-available TrueNAS M-Series has multiple layers of protection to help keep data safe, including data scrubs, checksums, unlimited snapshots, replication, and more. TrueNAS is also inherently scalable with data shares only limited by the number of drives connected to the pool. Perfect for archival storage, the deployed TrueNAS M50 will grow with the library’s content, easily expanding its storage capacity over time as needed. Supporting a variety of protocols, multi-petabyte scalability in a single share, and anytime, uninterrupted capacity expansion, the TrueNAS M-Series ticked all the right boxes. Youtube Video News Roundup FreeBSD 12.1-beta available FreeBSD 12.0 is already approaching one year old while FreeBSD 12.1 is now on the way as the next installment with various bug/security fixes and other alterations to this BSD operating system. FreeBSD 12.1 has many security/bug fixes throughout, no longer enables "-Werror" by default as a compiler flag (Update: This change is just for the GCC 4.2 compiler), has imported BearSSL into the FreeBSD base system as a lightweight TLS/SSL implementation, bzip2recover has been added, and a variety of mostly lower-level changes. More details can be found via the in-progress release notes. For those with time to test this weekend, FreeBSD 12.1 Beta 1 is available for all prominent architectures. The FreeBSD release team is planning for at least another beta or two and around three release candidates. If all goes well, FreeBSD 12.1 will be out in early November.

While MeetBSD caters to Silicon Valley BSD enthusiasts on even years, vBSDcon caters to East Coast and DC area enthusiasts on odd years. Verisign was again the key sponsor of vBSDcon 2019 but this year made a conscious effort to entrust the organization of the event to a team of community members led by Dan Langille, who you probably know as the lead BSDCan organizer. The result of this shift was a low key but professional event that fostered great conversation and brainstorming at every turn.
