AHV Virtualization

Nutanix AHV VM disk accidentially deleted ...

Ok, let’s get straight into the topic. On one of our VMs, we had 3 local disks and 5 NICs and we intended to remove 4 of the 5 NICs, which are no longer necessary. Instead of deleting the NIC in the last row, a disk in the last row has been deleted and no, a snapshot of the VM has unfortunately not been created. Is there any possibility to recover the deleted VM disk from this specific VM with AHV/CVM command line? Thanks in advance for any help! Regards,Didi7

All licenses reset before clean re-allocation on two production clusters

Hi Guys,Can anyone confirm that it is possible to unlicense one or two NX clusters that are in production in order to re-allocate the same licenses but smarter?Explanation: We have 2 clusters with 3 AOS Pro licenses sets (Cores + FLASH)Set1: first 3 nodes of cluster1 (2019, renewed 2022)Set2: first 3 nodes of cluster2 (2021, renewed 2024)Set3: 2 more nodes, one for each cluster (2022)We should then have set1 allocated for cluster1, set2 for cluster2 and set3 split between the 2 clusters but currently each set is used partially in cluster1 and 2 which is a mess for next licenses renewal…So my target would be to reclaim all the licenses for both clusters and then reallocate them, cleaner, through seamless licencing. Is that scenario possible without stopping the exploitation? Thanks for your advice and guidance.

Indexed search for SMB share?

Hi, I have seen a previous topic on this subject and noticed JeroenTielen said you need to add the share to the index of the windows machine to have it indexed on that specific machine. but how can you do such a thing when i see in Microsoft forum:Windows does not support indexing network shares. You may still search them, but this is done in real-time without indexing, so may be quite slow. what can i do to make searching in Nutanix shares faster?

3ノードクラスタ障害からの回復構築中の問題

こんにちは3ノードで運用していましたが、1ノードが故障したため、4ノード目を追加したのち障害ノードを削除するつもりでした。しかし、ノード追加してクラスタ拡張は完了と出たものの、4ノード目が正常は追加されていないように見えます。cluster statusを見ると4ノード目はMedusa以降がすべてDownとなっています。4ノード目は、追加前にmanage_ovsで設定変更を実施した際にWARNINGが出ていて、これを解消しないままノード追加をしてしまったのが不味かったのかもしれないのですが、復旧できるでしょうか？クラスタ拡張実施前に4ノード目で出ていたWARNINGは下記の通りです※全NICがbr0にアサインされている状態から、2nicのみbr0にしようとしましたnutanix@NTNX-51e75960-A-CVM:192.168.0.114:~$ manage_ovs --bridge_name br0 --bond_name br0-up --interface eth4,eth5 update_uplinks2024-04-13 12:40:07,181Z WARNING manage_ovs:1313 Failed to fetch gflags.
