Hi. I'm trying to setup a NFSv4 server, but I can't get it to work properly. Short version: When I try to read a file on the NFSv4 server, it hangs and floods my kernel logs with "Error: state recovery failed on NFSv4 server 192.168.0.1 with error 121". However everything else seems to working, I can use ls and stat and the uid/gid is correct. Long version: I have compiled my kernel (2.6.20-gentoo-r6) with needed NFS stuff $ cat /boot/config-2.6.20-gentoo-r6-1 | grep NFS CONFIG_NFS_FS=m CONFIG_NFS_V3=y # CONFIG_NFS_V3_ACL is not set CONFIG_NFS_V4=y CONFIG_NFS_DIRECTIO=y CONFIG_NFSD=m CONFIG_NFSD_V3=y # CONFIG_NFSD_V3_ACL is not set CONFIG_NFSD_V4=y CONFIG_NFSD_TCP=y CONFIG_NFS_COMMON=y I have loaded the modules $ lsmod Module Size Used by nfs 246456 3 nfsd 251304 17 exportfs 5568 1 nfsd lockd 66224 3 nfs,nfsd sunrpc 159624 14 nfs,nfsd,lockd I have installed the lates version of nfs-utils $ sudo emerge -pv nfs-utils [ebuild R ] net-fs/nfs-utils-1.0.12-r3 USE="-kerberos -nonfsv4 -tcpd" 0 kB I have setup a simple /etc/exports $ cat /etc/exports /tmp *(ro,sync,no_subtree_check,nohide,fsid=root) I start the nfs server $ sudo /etc/init.d/nfs start * Starting portmap ...

On my client machine I have managed to get a working NFSv4 server which can mount it's own nfs. I can even from the server machine mount the client machines nfs exports. So my guess is that it's something wrong in the NFSD part on the server machine. The server machine is running ResierFS on top of LVM on top of RAID5. But I have tried with a external USB stick and it's the same problem. $ sudo emerge --info Portage 2.1.2.2 (default-linux/amd64/2006.1, gcc-4.1.1, glibc-2.5-r0, 2.6.20-gentoo-r6 x86_64) ================================================================= System uname: 2.6.20-gentoo-r6 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ Gentoo Base System release 1.12.9 Timestamp of tree: Sat, 21 Apr 2007 15:50:01 +0000 dev-lang/python: 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.61 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.16.1-r3 sys-devel/gcc-config: 1.3.15-r1 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=athlon64" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb" CONFIG_PROTECT_MASK="/etc/env.d /etc/gconf /etc/php/apache1-php5/ext-active/ /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/terminfo" CXXFLAGS="-O2 -pipe -march=athlon64" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/distributions/gentoo" LANG="sv_SE.UTF-8" LC_ALL="sv_SE.UTF-8" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages --filter=H_**/files/digest-*" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage /usr/portage/local/layman/webapps-experimental" SYNC="rsync://rsync.gentoo.se/gentoo-portage" USE="alsa amd64 apache2 berkdb bitmap-fonts bzip2 cli cracklib crypt dri dvb fortran gd gdbm iconv isdnlog jpeg ldap libg++ midi mysql ncurses nls nolvm1 nptl nptlonly opengl pam pcre perl png ppds pppd python readline reflection samba session spl ssl threads truetype truetype-fonts type1-fonts unicode vhosts vorbis xml xml2 xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="nvidia" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LDFLAGS, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
try with nfs-utils-1.1.0 if that doesnt work, please seek help on the nfs lists
