Here is a bit of background. I have a fileserver running FreeBSD 4.7-STABLE. This has a 3ware Escalade with 4 x 80GB Maxtors in a RAID 5 config. I am exporting /usr/ports, among other things - 5 exports total to 2 clients. The clients are all running 4.7-Stable as well. Under 4.6.2, I was able to install ports with no problems on the clients. Now, patches don't seem to always work, files aren't always getting created, and 'Server Ret-Failed' from nfsstat -s increments quite rapidly. I hope there isn't any problems following this. # relevant info section: #######Fileserver####### 13:41:51:d_jab@aluminum (/dev/ttyp5): 15 ~ >> grep nfs /etc/rc.conf nfs_reserved_port_only="YES" nfs_server_enable="YES" nfs_server_flags="-u -t -n 20 -h 192.168.23.200" 13:40:12:d_jab@aluminum (/dev/ttyp5): 12 ~ >> grep twed /etc/fstab /dev/twed0s1b none swap sw 0 0 /dev/twed0s1h /home ufs rw,noatime,nosuid,nodev 2 2 /dev/twed0s1e /usr ufs rw,noatime 2 2 /dev/twed0s1d /usr/local/mp3 ufs rw,noatime,nosuid,nodev 2 2 /dev/twed0s1a /usr/local/storage ufs rw,noatime 2 2 /dev/twed0s1g /usr/ports ufs rw,noatime 2 2 /dev/twed0s1f /usr/src ufs rw,noatime 2 2 13:40:23:d_jab@aluminum (/dev/ttyp5): 13 ~ >> cat /etc/exports /usr/src -maproot=root -network 192.168.23 -mask 255.255.255.0 /usr/ports -maproot=root -network 192.168.23 -mask 255.255.255.0 /home -maproot=root -network 192.168.23 -mask 255.255.255.0 /usr/local/mp3 -maproot=root -network 192.168.23 -mask 255.255.255.0 /usr/local/storage -maproot=root -network 192.168.23 -mask 255.255.255.0 13:40:58:d_jab@aluminum (/dev/ttyp5): 14 ~ >> nfsstat -s Server Info: Getattr Setattr Lookup Readlink Read Write Create Remove 5749 67176 480135 60 191927 114932 40335 15174 Rename Link Symlink Mkdir Rmdir Readdir RdirPlus Access 23627 9 192 909 739 47 40300 661793 Mknod Fsstat Fsinfo PathConf Commit GLease Vacate Evict 0 53118 10 0 53650 0 0 0 Server Ret-Failed 242570 Server Faults 0 Server Cache Stats: Inprog Idem Non-idem Misses 0 4 0 803 Server Lease Stats: Leases PeakL GLeases 0 0 0 Server Write Gathering: WriteOps WriteRPC Opsaved 114906 114932 26 ###### Client ###### 13:43:50:d_jab@carbon (/dev/ttyp2): 6 ~ >> grep nfs /etc/rc.conf nfs_reserved_port_only="YES" nfs_client_enable="YES" nfs_client_flags="-n 6" 12:59:55:d_jab@carbon (/dev/ttyp2): 4 ~ >> grep nfs /etc/fstab al:/home /home nfs rw,nfsv3,tcp,intr,bg,rdirplus,noatime,-r=32768,-w=32768 00 al:/usr/ports /usr/ports nfs rw,nfsv3,tcp,intr,bg,rdirplus,noatime,-r=32768,-w=32768 0 0 al:/usr/src /usr/src nfs rw,nfsv3,tcp,intr,bg,rdirplus,noatime,-r=32768,-w=32768 0 0 al:/usr/local/mp3 /usr/local/mp3 nfs rw,nfsv3,tcp,intr,bg,rdirplus,noatime,-r=32768,-w=32768 00 al:/usr/local/storage /usr/local/storage nfs rw,nfsv3,tcp,intr,bg,rdirplus,noatime,-r=32768,-w=32768 0 0 13:42:42:d_jab@carbon (/dev/ttyp2): 5 ~ >> nfsstat -c Client Info: Rpc Counts: Getattr Setattr Lookup Readlink Read Write Create Remove 274 100450 596003 63 209637 193806 55717 26701 Rename Link Symlink Mkdir Rmdir Readdir RdirPlus Access 29939 27 195 1088 1084 0 43879 774525 Mknod Fsstat Fsinfo PathConf Commit GLease Vacate Evict 0 56651 16 0 41432 0 0 0 Rpc Info: TimedOut Invalid X Replies Retries Requests 0 0 10 617 2131487 Cache Info: Attr Hits Misses Lkup Hits Misses BioR Hits Misses BioW Hits Misses 8475243 579261 2735547 595897 4225460 198743 320897 193806 BioRLHits Misses BioD Hits Misses DirE Hits Misses 718 63 69134 41254 50367 14 ##################################################### Does anyone have any advice?
