Hi all.this is my first message in mail list, so correct me if I 'm wrong. I have a raspberry pi with kernel compiled from (sys-kernel/raspberrypi-source 3.6.11_r20130711,running nfsv4 server.To simplify problem, only a simple directory exported.
Senge-Raspi ~ # cat /etc/exports # /etc/exports: NFS file systems being exported. See exports(5). /export *(fsid=0,rw,no_subtree_check,no_root_squash) Senge-Raspi ~ # ls -l /export/ total 4 -rw-r--r-- 1 root root 4 Nov 18 12:48 test Senge-Raspi ~ # cat /export/test foo And on my laptop, as nfs client. senge@Senge-Laptop ~ $ cat /etc/fstab # <fs> <mountpoint> <type> <opts> <dump/pass> # NOTE: If your BOOT partition is ReiserFS, add the notail option to opts. /dev/sda1 /boot ext4 noauto,noatime 1 2 /dev/sda3 / ext4 noatime 0 1 /dev/sda2 none swap sw 0 0 /dev/sda4 /mnt/windows ntfs noauto 0 0 59.78.22.20:/ /raspi nfs4 rw,_netdev,auto,rsize=32768,wsize=32768 0 0 senge@Senge-Laptop ~ $ sudo rc-config restart nfsmount Restarting init script * Starting rpcbind ... [ ok ] * Starting NFS statd ... [ ok ] * Setting up RPC pipefs ... [ ok ] * Starting idmapd ... [ ok ] * Starting NFS sm-notify ... [ ok ] * Mounting NFS filesystems ... It hangs here. and in kernel message [19888.585247] RPC: Registered named UNIX socket transport module. [19888.585251] RPC: Registered udp transport module. [19888.585252] RPC: Registered tcp transport module. [19888.585253] RPC: Registered tcp NFSv4.1 backchannel transport module.

Exiting with error EIO sometimes mount succeed, and directory can be accessed. but reading files return error:(without 'dmesg' changed) senge@Senge-Laptop ~ $ sudo rc-config restart nfsmount Restarting init script * Starting NFS sm-notify ... [ ok ] * Mounting NFS filesystems ... [ ok ] senge@Senge-Laptop ~ $ cat /raspi/test cat: /raspi/test: Input/Output error But I actually have nfs support on server: Senge-Raspi ~ # zcat /proc/config.gz | grep -i nfs # CONFIG_NFS_FS is not set CONFIG_NFSD=y CONFIG_NFSD_V2_ACL=y CONFIG_NFSD_V3=y CONFIG_NFSD_V3_ACL=y CONFIG_NFSD_V4=y # CONFIG_NFSD_FAULT_INJECTION is not set CONFIG_NFS_ACL_SUPPORT=y CONFIG_NFS_COMMON=y However, official pre-compiled kernel(sys-kernel/raspberrypi-image 3.6.11-p20130730) worked fine, Senge-Raspi ~ # zcat /proc/config.gz | grep -i nfs CONFIG_NFS_FS=y CONFIG_NFS_V2=y CONFIG_NFS_V3=y CONFIG_NFS_V3_ACL=y CONFIG_NFS_V4=y # CONFIG_NFS_SWAP is not set # CONFIG_NFS_V4_1 is not set CONFIG_ROOT_NFS=y CONFIG_NFS_FSCACHE=y # CONFIG_NFS_USE_LEGACY_DNS is not set CONFIG_NFS_USE_KERNEL_DNS=y CONFIG_NFSD=m CONFIG_NFSD_V2_ACL=y CONFIG_NFSD_V3=y CONFIG_NFSD_V3_ACL=y CONFIG_NFSD_V4=y # CONFIG_NFSD_FAULT_INJECTION is not set CONFIG_NFS_ACL_SUPPORT=y CONFIG_NFS_COMMON=y I have googled a lot, return few result...any idea appreciated.(sorry for poor English)
