Hi,
I have a 4.3-BETA FreeBSD 4.3-BETA #0: Wed Mar 14 15:18:36 system
with an ATA based vinum raid5.
I am trying to copy a 1.7Mb user directory from a Solaris 7 system
to a directory on the FreeBSD vinum volume.
I have nfs mounted the FreeBSD vinum volume on the Solaris box
and started tar cbf 8 - . | ( cd ../r/usera; tar xbBf 8 - )
The Solaris system twice has stopped copying with the error
NFS server XXXX not responding still trying.
I rebooted the FreeBSD box after the first hang.
A ps on the FreeBSD box shows:
0 118 1 0 2 0 360 132 accept Is ?? 0:00.00 nfsd: master
0 120 118 0 -6 0 352 124 vrlock D ?? 0:03.71 nfsd: server
0 121 118 0 -14 0 352 124 inode D ?? 0:00.05 nfsd: server
0 122 118 0 -14 0 352 124 inode D ?? 0:00.04 nfsd: server
0 123 118 0 -14 0 352 124 inode D ?? 0:00.04 nfsd: server
The kernel was compiled with -g, otherwise it is a GENERIC kernel.
I presume that the FreeBSD nfsd has hung waiting on vrlock.
The system is otherwise usable, i.e. console works, remote access works.
