Nutanix的客户使用AHV作为其管理程序通常会在其群集上遇到磁盘空间问题，并且需要评估每个实体正在消耗多少磁盘空间。需要考虑的更重要的因素之一是每个VM占用多少空间。需要有一种简单的方法来运行一个命令并获取每个VM消耗的空间的列表，以便一眼就可以弄清楚哪些是可以立即从集群中删除的VM一些太空开垦。作为奖励，我还包括了命令字符串，该字符串将加起来所有这些数字，并为您提供所有这些VM所消耗的磁盘空间的总数。

我已经想到了以下字符串操作，以便能够获得这些数字：

nutanix@cvm：$ for q in`acli vm.list |awk'{print $ 1}'`; do echo -n“ $ q”;acli vm.get“ $ q” |grep vmdisk_size |awk'{sum+= $ 2}结束{print sum}'|awk'{字节= $ 1/1024/1024/1024;回声;打印字节“ gb”}';完成

nutanix@cvm：$ for q in`acli vm.list |awk'{print $ nf}'|egrep -v uuid`;做acli vm.get“ $ q” |grep vmdisk_size |awk'{sum+= $ 2}结束{print sum}'|awk'{字节= $ 1/1024/1024/1024;回声;打印字节“ GB”}';完成| awk '{total += $1} END {print "\nTotal space consumed by the VMs:", total, "GigaBytes"}'; echo

如上所述，将字符串操作与标准Linux操作（如GREP和AWK）结合使用，并涉及一些数学，我们可以在群集中每个VM占用多少磁盘空间上产生输出。您还可以查看所有这些VM的总磁盘空间已占用了多少。这使您更近一步，即可摆脱低悬挂的水果，并采取一种认知方法来删除其他VM。您决定是否要看森林还是森林中的单个树木！

请注意，以上命令仅用于监视和评估目的，它们不会对Nutanix群集进行任何更改。这为您提供了VM的手柄，让我们解决另一个删除候选者，即以后的帖子中的快照。

删除您可以立即摆脱的任何VM，深呼吸，然后三思而后行，然后删除其他VM。

Nutanix customers using AHV as their Hypervisor often run into disk space issues on their cluster and need to evaluate how much disk space is being consumed by each entity.\u00a0 And one of the more important factors that needs to be considered is how much space is being taken up by each VM.\u00a0 There needs to be an easy way of running one single command and get a listing of the space consumed by each VM, so that at one glance you can figure out which are the VMs that can be removed from the cluster right away in order to get some space reclamation.\u00a0 As a bonus I have also included the command string that will add up all these numbers and give you the grand total of how much disk space has been consumed by all these VMs put together.<\/span><\/p>

I have come up with the following string manipulation to be able to get those numbers:<\/span><\/p>

nutanix@CVM:$ for Q in `acli vm.list | awk '{print $1}'`;do echo -n \"$Q    \"; acli vm.get \"$Q\" | grep vmdisk_size | awk '{sum+=$2} END {print sum}' | awk '{ byte =$1 \/1024\/1024\/1024; echo; print byte  \" GB\" }';done

nutanix@CVM:$ for Q in `acli vm.list | awk '{print $NF}' | egrep -v UUID`; do acli vm.get \"$Q\" | grep vmdisk_size | awk '{sum+=$2} END {print sum}' | awk '{ byte =$1 \/1024\/1024\/1024; echo; print byte  \" GB\" }'; done | awk '{total += $1} END {print \"\\nTotal space consumed by the VMs:\", total, \"GigaBytes\"}'; echo
<\/code><\/pre>
As you can see above, using the string manipulation in conjunction with the standard Linux operations like grep and awk, and involving a bit of mathematics, we can produce the output on how much disk space every VM in the cluster has taken up.\u00a0 You are also able to see how much total disk space has been taken up by all these VMs put together.\u00a0 This gets you one step closer to getting rid of the low hanging fruits, and taking a cognizant approach to whether to delete the other VMs. \u00a0 You decide whether you want to look at the forest or at the individual trees in the forest!!!!!<\/span><\/p>
Please note that the above commands are for monitoring and evaluation purposes only, they do not make any changes in your Nutanix cluster.\u00a0 This gives you a handle on the VMs, let us tackle the other candidate for deletions i.e. the Snapshots in a later post.<\/span><\/p>
Delete whatever VMs you can get rid of immediately, take a deep breath and think twice before you delete the other VMs.<\/span><\/p>","quoteUsername":"Kiran Surya","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
