From 470f00562429b18b345f0560a5176c0f873f8e0e Mon Sep 17 00:00:00 2001 From: Qiang Chen Date: Fri, 25 Oct 2013 14:49:11 +0800 Subject: [PATCH] nfs-utils: nfsserver restart should kill and recreate nfsd kernel threads nfsserver restart without killing kernel threads worked when portmap was the rpc publishing process and portmap was restarted. When rpcbind replaces portmap, nfsserver restart in this way does not work after an rpcbind restart. Steps to reproduce: 1). Make ext3 filesystem image on local host. cd /root dd if=/dev/zero of=test bs=1024K count=50 mkfs.ext3 -F test 2). runqemu qemux86-64 mkdir /mnt/wrtest mount -t ext3 -o loop test /mnt/wrtest echo "/mnt/wrtest *(sync,rw,no_subtree_check,no_root_squash)" > /etc/exports /etc/init.d/rpcbind restart /etc/init.d/nfsserver restart showmount -e localhost mkdir wrtest mount -t nfs localhost:/mnt/wrtest wrtest mount: mounting localhost:/mnt/wrtest on wrtest failed: Connection refused Modifying the nfsserver script to kill and restart kernel threads on restart makes the problem go away and is consistent with current RHEL/SUSE and Ubuntu/Debian mechanisms of handling the nfs server.
