Ubuntu CEPH HEALTH_警告降级数据冗余：重新称重后pgs尺寸过小

我们有3台服务器和15台OSD的CEPH设置。两周前，我们收到了“2个OSD几乎满”的警告。我们使用下面的命令重新加载了OSD，并重新启动了两个OSD

ceph osd reweight-by-utilization

重新启动后，我们在过去两周内都处于警告之下

我是CEPH的新手，这是预期的行为吗？或者如何解决这个问题

ceph 13.2.6版（7b695f835b03642f85998b2ae7b6dd093d9fbce4）模拟（稳定）我们使用的是粉碎图，粉碎图中提到的OSD池重量是1，因此我们用一个来重新称量SSD OSD

#ceph osd reweight <OSD Number> 1

#ceph osd重新称重1

感谢@eblock的帮助。

我们使用的是crush map，我们的crush map中提到的OSD池重量是1，因此我们用一个重新加权SSD OSD

#ceph osd reweight <OSD Number> 1

#ceph osd重新称重1

---

谢谢@eblock的帮助。

您能编辑您的问题并添加

ceph osd df

输出吗？我假设重新称重没有足够的可用空间，无法成功完成。您唯一的选择是扩展群集并添加更多存储或删除未使用的数据以清除这些警告。请在问题中添加

ceph osd tree

。你能解释一下SSD是如何使用的吗？我甚至不知道osd树也有每个池的输出，你是怎么做到的？您正在运行哪个ceph版本？哪些池是39和54（

ceph osd池ls detail

）？我仍然不了解全部情况。这是哪种ceph版本？我想知道为什么每个池输出和常规osd树输出中的压碎重量不同。无论如何，我会尝试将SSD的重量重新调整为1，如果您有3个SSD，但将所有的重新重量平均减少，这是没有意义的。如果运行ceph osd crush reweight osd.11，并对其他两个SSD重复该操作，会发生什么情况？重新称重不会清除任何数据，只会重新洗牌。因此，如果您执行我建议的命令，您的数据将不会发生任何变化。您可以编辑您的问题并添加
