Ravinred — Wed, 11 May 2022 21:10:01 GMT

Hello Everyone,

NSX Manager crashed and cannot boot up do to disk errors. Cannot boot to GRUB to resolve because the GBUB menu does not let you in edit mode. Booted to Ubuntu disk and ran FSCK against all disks, but NSX manager still will not boot up or let you edit GRUB menu.

I would like to un-install the nsx manager on vCenter and Esxi hosts but i don't have the NSX Manger UI access.

How do i Un-install can someone please help me on this

NSX-Tà Version 3.2.0.1.0.19232396 And ESXià VMware ESXi, 7.0.3, 19193900
We don’t have 3 NSX Mangers in the cluster we have only one.

Thank you

How to safely delete “Zombie” VMDK files

Ravinred — Tue, 11 May 2021 18:23:39 GMT

Hello Everyone,

I work in an environment that has over 4500 VMs and I'm trying to clean it up. One of the things I wanted to clean up is zombie VMDK files which according to RVTools, I have plenty. I don't want to do it manually but I think a script is pretty "dangerous".

What is the proper way of deleting those files?

Thank you,

Ravi
