Azure NetApp Files NFSv3 destination volume in availability zone AZ02Īutomounter is a package you can install on nearly any Linux distribution that does exactly what it says it does – provides automatic mount functionality.Azure NetApp Files NFSv3 source volume in availability zone AZ01.The following environmental configuration was used for this example. With automounter, it is possible to provide faster failovers to volume replicas in the event of an outage in your source volume’s availability zone. If there are many clients, remounts can be a challenging task to perform.īut what if you could automate the failover process to avoid requiring any admin interaction with a few simple configuration changes? There will also likely be different IP addresses in the Virtual Network (VNet), so in the event of a failover, a remount would be needed to gain access to the replicated volume. Only two volumes can be deployed in a region with Azure NetApp Files – even in different availability zones – and the names must be different. With Azure NetApp Files, volumes can be replicated across availability zones within a region to provide redundant copies of important datasets, but failover is a manual process with several steps that can take valuable time away from your application. Networks can fail, zones can go down, and then your application is left in a nebulous state waiting for the NFS mount to respond to read or write operations. When you are using NFS in the cloud for your business-critical applications, you can ill-afford outages. ![]() This article covers how to configure autofs for automatic mount failovers in Azure NetApp Files.Ĭo-authors: Justin Parisi, Azure NetApp Files Technical Marketing Engineer Looking for a way to automate NFS mount failovers when a network or availability zone becomes unavailable?

I actually had the same problem, but i was doing it via fstab so i am not sure how much it is applicable to your issue. To make the automount works until the next boot.ĭoes anyone know what keeps the unit from working automatically? I check the unit status on a fresh boot and it shows the unit was loaded, active, and waiting, so I suppose it was successfully loaded, but didn’t work for some reason. I need to restart the automount unit by sudo systemctl daemon-reload However, after the successful setup, the automount unit failed to work at the next time I turned on the computer. Every time I access /home/esom, it will mount the samba share for me. I enabled the automount unit and it seems to work fine. Options=_netdev,iocharset=utf8,rw,file_mode=0777,dir_mode=0777,credentials=/etc/samba/esom.credentialĪnd the automount unit is like below: ![]() Only use an automount unit if the device is not readily available at boot like removable devices and network locations.
