For unknown reason the filesystem on NSX-Manager will go bad and to recovering from this is different when compared with other filesystem recovery methods.
Problem: NSX Manager VM unable to boot. you will a screen something like below:
- Download and Connect the Ubuntu ISO to CD drive of the NSX-Manager VM.
- Boot through CD drive and choose "try now" option.
- Run the recovery command "fsck /dev/sda2"
- NSX-Manager VM will recover back from the filesystem and will boot normally.
