Is there a way to partly revoke NFS export, temporarily? Say I export /export/foo and /export/bar and I want to fsck /export/foo while continuing to export /export/bar.
What would happen if I remove /export/foo from /etc/exports (and HUP mountd) and then unmount it? Would NFS clients get ESTALE for any files they happen to have open? Is there a way to make them just hang on those files until I re-mount and re-export the file system?
