synology nas as storage lock what looks like to be entire nodes and VMs

Hi all,

So i have a single Synology DS1513+ which servers my 3 proxmox nodes with NFS access as vm, iso and template storage..

I have noticed from time to time when i simulate certain break downs in my system the NAS kind locks the VM or entire nodes even. Its so serviver that i have to reboot the NAS to get my proxmox nodes to talk to it agian..

does anyone else have know of this problem and maybe can explain what is happening?

Thanks

Casper
