如果在其他地方得到了回答，我深表歉意，但我找不到它，所以也许还没有。我敢肯定，其他人会陷入这种情况。

我有一个基于旧超级套件的3个节点Nutanix群集。每个节点都有3个磁盘：1 x 240GB SSD1、1 x 250GB HDD和1 x 1.0TB HDD。我从节点1删除了250GB HDD，以证明在拉动磁盘时继续工作。

我在一天的剩余时间里遗漏了它，发现它已经失败了。我相信这很正常。然后，我将其推回去。我希望必须做些事情才能再次被识别，但我找不到那是什么。

它被主机识别为 /dev /sda： -

代码：

[root@ntnx-baff460a-a〜]＃lsscsi
[0：0：0：0]磁盘ATA WDC WDC WD2502ABYS-0 3B03 /dev /sda
[0：0：1：0]磁盘ATA WDC WDC WD10EZEX-08W 1A02 /dev /sdb
[1：0：0：0]磁盘ATA Kingston SA400S3 61E1 /dev /sdc
[4：0：0：0]磁盘Kingston DataTraveler 3.0 /dev /sdd

CVM也识别为 /dev /sda： -

代码：

nutanix@ntnx-baff460a-a-cvm：192.168.2.31：〜$ lsscsi
[1：0：0：0] CD/DVD QEMU QEMU DVD-ROM 2.5+/DEV/SR0

[2：0：0：1]磁盘ATA WDC WDC WD10EZEX-08W 2.5+ /dev /sdc
[2：0：0：2]磁盘ATA Kingston SA400S3 2.5+ /dev /sdb

但是，它不会出现DF -F。

代码：

nutanix@ntnx-baff460a-a-cvm：192.168.2.31：〜$ df -h

I’ve tried running the ‘add-all-free-disks’ command but that just shows the existing size of the storage pool and the disks that are already in it so I’m guessing it is not finding that the 250GB disk is one that can be added to the Cluster.

代码：

如果我必须从群集中删除节点，请重新图像并将其添加进一步以使磁盘再次加入，我会这样做，但我希望通过浏览此过程来学习一些东西。我已经通过探索选项学到了一些东西。

谢谢！

\r\nI have a 3 node Nutanix Cluster based on old SuperMicro kit. Each node has 3 disks: 1 x 240GB SSD1, 1 x 250GB HDD and 1 x 1.0TB HDD. I removed the 250GB HDD from Node 1 to demonstrate that things continue working when a disk is pulled.
\r\n
\r\nI left it out for the rest of the day and found that it had been failed out of the cluster. This is normal I believe. I then pushed it back in. I was expecting to have to do something to get it to be recognised again but I can\u2019t find out what that is.
\r\n
\r\nIt\u2019s recognised by the host as \/dev\/sda:-

\r\nIf I have to remove the node from the cluster, re-image it and add it in again to get the disk in again I\u2019ll do so but I\u2019m hoping to learn something by going through this process. I\u2019ve already learned a few things by exploring the options.
\r\n
\r\nThanks!

啊！是的。我不知道： -

代码：
nutanix@ntnx-baff460a-a-cvm：192.168.2.31：〜$ ncli磁盘列表 - 汤匙 - 汤匙 - 进入

序列号：50014EE2048288F1

我运行了命令，它不在列表中： -

代码：
nutanix@ntnx-baff460a-a-cvm：192.168.2.31：〜$ ncli磁盘rm-tombstone-tombstone-Entry serial-number = 50014EE2048288F1
磁盘'50014EE2048288F1'从墓碑条目中删除

我再次运行了附加磁盘命令，但它只是产生了相同的结果。计数8个磁盘和相同的容量。还有其他要做的事情以及将它们从墓碑清单中删除吗？

\r\nI ran the command and it's not in the list anymore:-

\r\nI ran the add-all-free-disks command again but it just produced the same result. A count of 8 disks and the same capacity. Is there something else to do as well as removing them from the tombstone list?","quoteUsername":"Owen Hopkins","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

此信息看起来有些过时，但是可能会在当前的CVM上起作用的某些可重新启动和干净的命令。
