Btrfs to be the Default Filesystem on Fedora? Fedora 33 Starts Testing Btrfs Switch
|
||||
======
|
||||
|
||||
While we’re months away from Fedora’s next stable release ([Fedora 33][1]), there are a few changes worth keeping tabs on.
|
||||
|
||||
Among all the other [accepted system-wide changes for Fedora 33][1], the proposal of having Btrfs as the default filesystem for desktop variants is the most interesting one.
|
||||
|
||||
Here’s what Fedora mentions for the proposal:
|
||||
|
||||
> For laptop and workstation installs of Fedora, we want to provide file system features to users in a transparent fashion. We want to add new features, while reducing the amount of expertise needed to deal with situations like running out of disk space. Btrfs is well adapted to this role by design philosophy, let’s make it the default.
|
||||
|
||||
It’s worth noting that this isn’t an accepted system-wide change as of now and is subject to tests made on the [Test Day][2] (**8th July 2020**).
|
||||
|
||||
So, why is Fedora proposing this change? Is it going to be useful in any way? Is it a bad move? How is it going to affect Fedora distributions? Let’s talk a few things about it here.
|
||||
|
||||
![][3]
|
||||
|
||||
### What Fedora Editions will it Affect?
|
||||
|
||||
As per the proposal, all the desktop editions of Fedora 33, spins, and labs will be subject to this change, if the tests are successful.
|
||||
|
||||
So, you should expect the [workstation editions][4] to get Btrfs as the default file system on Fedora 33.
|
||||
|
||||
### Potential Benefits of Implementing This Change
|
||||
|
||||
To improve Fedora for laptops and workstation use-cases, Btrfs file system offers some benefits.
|
||||
|
||||
Even though this change hasn’t been accepted for Fedora 33 yet – let me point out the advantages of having Btrfs as the default file system:
|
||||
|
||||
* Improves the lifespan of storage hardware
|
||||
* Providing an easy solution to resolve when a user runs out of free space on the root or home directory.
|
||||
* Less-prone to data corruption and easy to recover
|
||||
* Gives better file system re-size ability
|
||||
* Ensure desktop responsiveness under heavy memory pressure by enforcing I/O limit
|
||||
* Makes complex storage setups easy to manage
|
||||
|
||||
|
||||
|
||||
If you’re curious, you might want to dive in deeper to know about [Btrfs][5] and its benefits in general.
|
||||
|
||||
Not to forget, Btrf was already a supported option — it just wasn’t the default file system.
|
||||
|
||||
But, overall, it feels like the introducing of Btrfs as the default file system on Fedora 33 could be a useful change, if implemented properly.
|
||||
|
||||
### Will Red Hat Enterprise Linux Implement This?
|
||||
|
||||
It’s quite obvious that Fedora is considered as the cutting-edge version of [Red Hat Enterprise Linux][6].
|
||||
|
||||
So, if Fedora rejects the change, Red Hat won’t implement it. On the other hand, if you’d want RHEL to use Btrfs, Fedora should be the first to approve the change.
|
||||
|
||||
To give you more clarity on this, Fedora has mentioned it in detail:
|
||||
|
||||
> Red Hat supports Fedora well, in many ways. But Fedora already works closely with, and depends on, upstreams. And this will be one of them. That’s an important consideration for this proposal. The community has a stake in ensuring it is supported. Red Hat will never support Btrfs if Fedora rejects it. Fedora necessarily needs to be first, and make the persuasive case that it solves more problems than alternatives. Feature owners believe it does, hands down.
|
||||
|
||||
Also, it’s worth noting that if you’re someone who does not want btrfs in Fedora, you should be looking at [OpenSUSE][7] and [SUSE Linux Enterprise][8] instead.
|
||||
|
||||
### Wrapping Up
|
||||
|
||||
Even though it looks like the change should not affect any upgrades or compatibility, you can find more information on the changes with Btrfs by default in [Fedora Project’s wiki page][9].
|
||||
|
||||
What do you think about this change targeted for Fedora 33 release? Do you want btrfs file system as the default?

Btrfs 将成为 Fedora 上的默认文件系统？ Fedora 33 开始测试切换到 Btrfs
|
||||
======
|
||||
|
||||
尽管距离 Fedora 的下一个稳定版本（[Fedora 33][1]）还有几个月的距离，但仍有一些值得关注的变化。
|
||||
|
||||
在所有其他 [Fedora 33 接受的系统范围的更改][1]中，最有趣的提议是将 Btrfs 作为桌面的默认文件系统。
|
||||
|
||||
这是 Fedora 对该提案的评价：
|
||||
|
||||
>对于 Fedora 的笔记本电脑和工作站安装，我们希望以透明的方式向用户提供文件系统功能。我们希望添加新功能，同时减少处理磁盘空间不足之类的情况所需的专业知识。Btrfs 它的设计理念非常适合这个角色，让我们将其设为默认设置。
|
||||
|
||||
值得注意的是，到目前为止，这不是系统范围内的更改，并且需要在[测试日][2]（**2020 年 7 月 8 日**）进行测试。
|
||||
|
||||
那么，为什么 Fedora 提出这一更改？这会有什么用么？这是糟糕的举动吗？对 Fedora 的发行有何影响？让我们在这里谈论下。
|
||||
|
||||
![][3]
|
||||
|
||||
### 它会影响哪些 Fedora 版本？
|
||||
|
||||
根据提议，如果测试成功，那么Fedora 33、spins 和 labs 的所有桌面版本都可能发生此更改。
|
||||
|
||||
因此，你可以期望[工作站版本][4]将 Btrfs 作为 Fedora 33 上的默认文件系统。
|
||||
|
||||
### 实施此更改的潜在好处
|
||||
|
||||
为了改进笔记本和工作站用例的 Fedora，Btrfs 文件系统提供了一些好处。
|
||||
|
||||
即使 Fedora 33 尚未接受此更改，但我先说下使用 Btrfs 作为默认文件系统的优点：
|
||||
|
||||
* 延长存储硬件的使用寿命
|
||||
* 提供一个简单的方案来解决用户耗尽根目录或主目录上的可用空间的情况。
|
||||
* 不易损坏数据，易于恢复
|
||||
* 提供更好的文件系统大小调整功能
|
||||
* 通过强制 I/O 限制来确保桌面在高内存压力下的响应能力
|
||||
* 使复杂的存储设置易于管理
|
||||
|
||||
|
||||
|
||||
如果你感到好奇，你可能想更深入地了解[ Btrfs][5] 及其总体优点。
|
||||
|
||||
不要忘记，Btrf 已经是受支持的选项，但它不是默认的文件系统。
|
||||
|
||||
但是，总的来说，感觉是引入 Btrfs 作为 Fedora 33 上的默认文件系统，如果实施得当，这可能会是一个有用的更改。
|
||||
|
||||
### Red Hat Enterprise Linux 可以实现吗？
|
||||
|
||||
很明显，Fedora 被认为是 [Red Hat Enterprise Linux][6] 的前沿版本。
|
||||
|
||||
因此，如果 Fedora 拒绝更改，那么 Red Hat 将不会实施。另一方面，如果你希望 RHEL 使用 Btrfs，那么 Fedora 应该首先同意更改。
|
||||
|
||||
为了让你更加清楚，Fedora 对其进行了详细介绍：
|
||||
|
||||
> Red Hat 在许多方面都很好地支持 Fedora。但是 Fedora 已经与上游紧密合作，并依赖上游。这将是其中之一。这是该提案的重要考虑因素。社区有责任确保它得到支持。如果 Fedora 拒绝，那么 Red Hat 将永远不会支持 Btrfs。Fedora 必然需要是第一位的， 并提出令人信服的理由， 它解决的问题比替代方案多。功能所有者相信它， 这是毫无疑问的。
|
||||
|
||||
另外，值得注意的是，如果你不想在 Fedora 中使用 btrfs，你应该看看 [OpenSUSE][7] 和 [SUSE Linux Enterprise][8]。
|
||||
|
||||
### 总结
|
||||
|
||||
即使这个更改看起来不会影响任何升级或兼容性，你也可以在 [Fedora 项目的 Wiki 页面][9]中找到有关 Btrfs 的更改的更多信息。
|
||||
|
||||
你对针对 Fedora 33 发行版的这一更改有何看法？你是否要将 btrfs 文件系统作为默认文件系统？
