NFS server: FreeBSD 4.7
Old Mail server: FreeBSD 4.7, home directories mounted to NFS server
New Mail server: FreeBSD 5.3, home directories mounted to NFS server
After the mail server upgrade to 5.3, flock gives error "operation not supported"
on nfs mounted home directories. Example:
Jan 13 00:06:32 mail vacation[92816]: vacation: .vacation: Operation not supported
output from "truss"
open(".vacation.db",0x2,0640) = 3 (0x3)
fstat(3,0xbfbfd350) = 0 (0x0)
flock(0x3,0x2) ERR#45 'Operation not supported'
close(3) = 0 (0x0)
It appears someone else has done substantially more debugging than I:
http://lists.freebsd.org/pipermail/freebsd-questions/2004-September/059777.html
but is seemingly no further ahead.
On our NFS server, rpc.statd is running, but rpc.lockd wasn't. Started
it, still no worky. Killed it, other 4.7 clients still flock fine.
Any suggestions for a fix or workaround so "vacation" works (which depends
on flock) ?
Thanks,
