Hi! Can someone pointme in the right place to insert the correct syntax to have multiple NFS mount options? I can only set one. Also, is there a complete list of options somwhere? thanks!

The NFS mount options are a string, and they work exactly the same as with the "-o" option to the "mount" command in Linux. I.e. you can set them to "rsize=65536,wsize=65536,hard,nolock"

this is what I have currently:
{
"version": 1,
"storageDriverName": "ontap-nas-flexgroup",
"backendName": "tbc-ontap-nas-flexgroup",
"managementLIF": "172.23.67.20",
"dataLIF": "172.23.71.253",
"svm": "svm-ctlabshared-tri01",
"username": "vsadmin",
"password": "netapp123!",
"limitAggregateUsage": "85%",
"limitVolumeSize": "50Ti",
"spaceReserve": "none",
"autoExportCIDRs": ["172.23.71.0/24"],
"autoExportPolicy": true,
"nfsMountOptions": "nfsvers=4.1, wsize=262144, rsize=262144, nconnect=8",
"storagePrefix": "nfs_fg_trident_",
"snapshotPolicy": "default"

}

#

so I can just delete the snapces under nfsmountoptions?

#

Sorry. What snapces?

#

Just change the mount options to what you want it to look like

ok will try again. It appeared to only mount using the first option nfsv4.1 and ignored the rest but let me try again. Thanks for helping 🙂

Some of those, like spaceReserve and snapshotPolicy, belong in a defaults section. See https://docs.netapp.com/us-en/trident/trident-use/ontap-nas-examples.html#backend-configuration-options-for-provisioning-volumes

Thanks! I did see that under some of the sample set. I will update them as well.

Thanks guys for the help! all the options are working as intended!

#

Can I ask if there is a preference or benefit for configuring backends using tridentctl vs kubectl?

#

Personally, I prefer doing everything with kubectl, as I don't need another binary for that (and tridentctl is x86-only so I can't use it on my RaspberryPi for example 😉 )
