Hi, i tried to set up a pnfs-server with a blocklayout. I used the howto from http://wiki.linux-nfs.org/wiki/index.php/PNFS_Block_Server_Setup_Instructions. I compiled the sources from the pnfs-all-3.3 branch. Exactly the sources with SHA1-Tag 4f32d9efd121222cf8a158b37563aac197da9d41. Starting ctl like described in the howto and connect to the server i got the following output from dmesg on the server: [70239.578792] BUG: unable to handle kernel paging request at ffffeddfff6dea80 [70239.578822] IP: [<ffffffff811a0889>] kfree+0x49/0x2a0 [70239.579017] PGD 0 [70239.579020] Oops: 0000 [#1] SMP [70239.579083] CPU 0 [70239.579085] Modules linked in: xfs btrfs zlib_deflate libcrc32c tcp_lp nls_utf8 hfsplus hfs vfat fat be2iscsi iscsi_boot_sysfs bnx2i cnic uio cxgb4i cxgb4 cxgb3i libcxgbi cxgb3 mdio ib_iser rdma_cm ib_cm iw_cm ib_sa ib_mad ib_core ib_addr iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi fuse ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter fcoe libfcoe ip6_tables libfc 8021q garp stp llc scsi_transport_fc scsi_tgt snd_ens1371 gameport snd_rawmidi snd_ac97_codec ac97_bus ppdev snd_seq joydev snd_seq_device snd_pcm vmw_balloon microcode pcspkr snd_timer snd pcnet32 parport_pc floppy parport soundcore snd_page_alloc mii shpchp i2c_piix4 i2c_core uinput nfsd lockd nfs_acl auth_rpcgss sunrpc mptspi mptscsih mptbase scsi_transport_spi [last unloaded: nf_defrag_ipv4] [70239.579240] [70239.579267] Pid: 15759, comm: ctl Tainted: G W 3.3.0-pnfs #1 VMware, Inc.
