Client v3 for windows 10.Top Windows NFSv3.0 Issues, Workarounds and Best Practices
Due to this, share locks, byte range locks from the client are lost during storage failover operations which involves lif failovers takeover-giveback,panic giveback,revert etc. This results in IO disruptions in the client. Error messages similar to the following might be reported: ' Error no. Description: NFS servers maintain a replay cache for non-idempotent operations sent from clients.
This replay cache holds the response to the original non-idempotent operation from the client. This is required to provide the same response to re-transmit the requests. Processing the re-transmitted request again, has different and unexpected results. Workaround: 1. Check syntax of command Correct syntax can be found here. Mismatch of NFS versions between client and server 3. Last workaround can be found here. Applies to Windows NFSv3. Also, this makes the volume move non disruptive.
Prior to a planned storage failover, make sure all the Windows NFS clients are unmounted. This prevents any outstanding NLM locks from being left in the cluster. After unplanned storage failures, remount Windows NFS clients.
This operation will force the client to properly cleanup any stale NLM locks created by client. Run the nfs server modify -vserver NFSshowmount enable to enable it. To view previously created volumes or qtrees, run the cache clear export-policy cache flush -vserver SVM -cache showmount command.
