June 2021 FreeBSD Developer Summit: Raid-Z Expansion
推荐理由
For those that like videos more than text, there is a youtube video from last year [1] that explain the feature
说明
这是2021年由FreeBSD发布的一部演讲,主题归在Databases & storage。它讲的是zfs raid-z expansion这一支里的具体问题,而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成:Matt Ahrens presents the FreeBSD Foundation sponsored RAID-Z Expansion project for ZFS at the June 2021 FreeBSD Developer Summit. It explains how a RAID-Z vdev can be grown by adding disks on the fly.这些读者给出的理由,核心是:HN points to it as the video explanation of how RAID-Z expansion works without block pointer rewrite.它贴着当时的技术,看的时候要记得那是那个年份的判断。从2021年到2023年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合一次性看完。讲者把一个判断讲透,演示是在给这个判断配例子。如果已经会了基本定义,就把注意力放在它怎么把zfs raid-z expansion变成能跟着复述的例子。
