I have exactly same problem on 4.0-current. Does anyone knows howto force umount -f to work? I didn't had any problems with udp mounted nfs export like this but copying ~700mb of data took about 20min to copy, and on tcp it's about 25 seconds. -- best regards q# # mount 192.168.9.121:/mnt/storage/pub on /home/disks/nfs type nfs (nodev, nosuid, read-only, v3, tcp, soft, intr, timeo=100) 192.168.9.121:/mnt/storage/upload on /home/disks/nfs_rw type nfs (nodev, nosuid, v3, tcp, soft, intr, timeo=100) # fstab 192.168.9.121:/mnt/storage/pub /home/disks/nfs nfs ro,-b,-T,-i,-s,nodev,nosuid,noauto 0 0 192.168.9.121:/mnt/storage/upload /home/disks/nfs_rw nfs rw,-b,-T,-i,-s,nodev,nosuid,noauto 0 0 OpenBSD 4.0-current (ACPI) #9: Tue Jan 2 07:55:07 MST 2007 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/ACPI cpu0: Intel(R) Pentium(R) M processor 1.86GHz ("GenuineIntel" 686-class) 1.87 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,TM,SBF,EST,TM2 real mem = 1073119232 (1047968K) avail mem = 970752000 (948000K) using 4256 buffers containing 53780480 bytes (52520K) of memory mainbus0 (root) bios0 at mainbus0: AT/286+(00) BIOS, date 10/02/05, BIOS32 rev. 0 @ 0xffe90, SMBIOS rev. 2.3 @ 0xf7860 (60 entries) bios0: Dell Inc.
