D May05 0:02 /0/tmp/av_explore .index /net/arc295/0/DQ_crawl26.20030416034937.arc.gz ...... although the nfs server has no problem at all. If I try to "ls /net/arc295/0" then the new "ls" process will hang as well. The method I followed to fix the problem is: [root@arc100 root]# umount -f /net/arc295/0 umount2: Device or resource busy umount: /net/arc295/0: Illegal seek [root@arc100 root]# /etc/init.d/amd restart Stopping amd: [ OK ] Starting amd: [ OK ] [root@arc100 root]# cd /net/arc295/0 [root@arc100 0]# ls=20 My nfs clients/servers has the same configurations:=20 Redhat 8.0 General Linux Kernel 2.4.20 ("nfs over tcp" is enabled) gcc-3.2-7=20 amd ( am-utils-6.0.7-9 ) amd mount options in map amd.master (opts:=3Drw,intr,nfsv3,tcp,nosuid,nodev,noresvport) The real amd mount status for the nfs directory: arc295:/0 on /.amd_mnt/arc295/host/0 type nfs (rw,intr,nfsv3,tcp,nosuid,nodev,noresvport,dev=3D0000f10e,vers=3D3,proto= =3Dtcp) Any one need more info the shoot the sort of problem, let me know.
