Given the snap was taken in 3.1.3, nfs.disable option was not touched. Now when this snap is restored, GlusterD didn't bring up the NFS service as nfs.disable is not set to off as per the current code logic.

@Jiffin - please confirm if this hypothesis is correct.

I think this needs to be marked as a known issue with a work around.

Hi jiffin,

I have updated the doc text further for the release notes, let me know if this looks ok.
