no access to nfs

[ds(ds)]

Suddenly dependent cluster (firstProxmox + second Proxmox).
secondProxmox broken (motherboard problem), and on firstProxmox not Login To webGUI (only via "ssh service pvedaemon restart")
made as follows:
#pvecm e 1
#pvecm delnode secondProxmox

Power off the virtual machine to firstProxmox and rebooted.
After the reboot, do not have access to the nfs storage.

How to see that for an error when scanning and connected to nfs?
