hi, i recently migrated our news box (which runs approx. 1MB/s nntp traffic inbound and >2MB/s outbound) to several systems and got the spool onto a vinum volume that spans 6 scsi busses (adaptec 3940UW) each 4 disks (IBM DNES 18GB). theres a private switched interconnect between the reader box and the "fileserver" now and nfs seem to crash on me somehow. nnrpd start to die after a few megabytes transfer and if i do an fstat -vp on one of the nnrpd's i get root@NEWS:black[~]31# fstat -vp 3820 USER CMD PID FD MOUNT INUM MODE SZ|DV R/W news nnrpd 3820 root / 2 drwxr-xr-x 512 r news nnrpd 3820 wd /sp 158720 drwxrwxr-x 923136 r news nnrpd 3820 text / 376 -r-xr-xr-x 90424 r news nnrpd 3820 0* internet stream tcp news nnrpd 3820 1* internet stream tcp news nnrpd 3820 2* internet stream tcp news nnrpd 3820 3* local dgram d4c7f400 <-> d4c7efc0 news nnrpd 3820 4* internet dgram udp d44b1600 news nnrpd 3820 5 /sp 158720 drwxrwxr-x 923136 r news nnrpd 3820 12* local dgram d4c7fe40 example lsof output of one of the dead nnrpd's: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME nnrpd 3820 news rtd VDIR 4,131072 512 2 / nnrpd 3820 news txt VREG 4,131072 90424 376 /home/news/bin/nnrpd nnrpd 3820 news txt VREG 4,131078 63832 182626 /usr/libexec/ld-elf.so.1 nnrpd 3820 news txt VREG 4,131078 7579 39707 /usr/lib/libscrypt.so.2 nnrpd 3820 news txt VREG 4,131078 31855 39805 /usr/lib/libutil.so.2 nnrpd 3820 news txt VREG 4,131078 517727 39742 /usr/lib/libc.so.3 nnrpd 3820 news 0u inet 0t0 TCP can't read inpcb at 0x00000000 nnrpd 3820 news 1u inet 0t0 TCP can't read inpcb at 0x00000000 nnrpd 3820 news 2u inet 0t0 TCP can't read inpcb at 0x00000000 nnrpd 3820 news 3u unix 0xd42353c0 0t0 ->0xd422edc0 nnrpd 3820 news 4u inet 0xd44b1600 0t0 UDP localhost:1276->localhost:1119 nnrpd 3820 news 5r VDIR 130,1 923136 158720 /sp/art/alt/binaries/sounds/mp3 nnrpd 3820 news 12u unix 0xd422e320 0t0 ->(none) system config is as follows: both boxes running freebsd 3.3-RELEASE fileserver backend tyan tomcat ii (i440BX) bios 1.18 p-iii 450 (options I686_CPU, NO_F00F_HACK) 256m sdram (will be 768m sdram/ecc) ahc[0..5] 3x aha-3940uw (options AHC_ALLOW_MEMIO) da0 ibm dnes 9GB uw da[1..24] 24x ibm dnes 18GB uw fxp0 intel etherexpress pro 100+/server (options NMBCLUSTERS=8192) media 100BaseTX mediaopt full-duplex filesystems on vinum w/ softupdates /db stripe, 4disks, 68GB /sp stripe, 20disks, 341GB nfs_server_flags="-u -t -n 16" newsreader frontend asus p2b-s (i440BX) bios 1011 p-iii 450 (options I686_CPU, NO_F00F_HACK) 512mb sdram (will be 1gb sdram/ecc) ahc0 adaptec u2w onboard da0 ibm dnes 9GB u2w fxp[0,1] intel etherexpress pro100+/server (options NMBCLUSTERS=8192) media 100BaseTX mediaopt full-duplex fxp0 -> internet fxp1 -> private storage network 10.0.0.0/24 nfs_client_flags="-n 8" fstab: bucket:/sp /sp nfs \ rw,bg,noatime,-r=1024,-w=1024,intr,-a=3,-d,-t=10 0 0 bucket:/db /db nfs \ rw,bg,noatime,-r=1024,-w=1024,intr,-a=3,-d,-t=10 0 0 the main question: why do those guys hang there? the nnrpd i use is from the inn-1.7.2-insync+actived distribution/patchkit any ideas? as far as i understand it chokes because of nonexistent pcb's that are set 0, but i'm not this deep into nfs anyway... any help appreciated... /k -- > "There is a God, but He drinks" -- Blore http://www.nacamar.de - http://www.nacamar.net - http://www.webmonster.de http://www.apache.de - http://www.quakeforum.de - finger rohrbach@nacamar.net KR433/KR11-RIPE - PGP-KFP = F9 A0 DF 91 74 07 6A 1C 5F 0B E0 6B 4D CD 8C 44 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
