Description of problem: Attempt NFSv4 loopback mount never completes. Version-Release number of selected component (if applicable): nfs-utils-1.0.7-1 How reproducible: Attempt NFSv4 loopback mount. Steps to Reproduce: - Setup /etc/extports to export a filesystem in a way that NFSv4 understands. /mnt/testfs *(rw,fsid=0,insecure,no_subtree_check,sync) - increase the number of NFSD threads to 32 echo "32" >/etc/sysconfig/nfs - start nfs service /etc/init.d/nfs start - mount the filesystem through loopback as type nfs4 mount -t nfs4 -o nocto,rsize=32768,wsize=32768 localhost:/ /mnt/testfs_loopback -HANG Actual results: HANG Expected results: loopback mount Additional info: This works fine on Gentoo.
Just to be clear, what is the kernel version your using?
I had been running kernel-smp-2.6.11-1.1177_FC4 with nfs-utils-1.0.7-1. I have since upgraded to kernel-smp-2.6.11-1.1226_FC4 and nfs-utils-1.0.7-5.
It seems to be working now... # showmount -e Export list for xxx.xxx.xxx.xxx /var/tmp * # mount -t nfs4 -o nocto,rsize=32768.wsize=32768 localhost:/ /mnt/ # mount ... localhost:/ on /mnt type nfs4 (rw,nocto,rsize=32768.wsize=32768,addr=127.0.0.1)
