Hi,
I'm running OpenBSD, current as of 16/11-2015, in VirtualBox 5.0.10 on
an Apple system, for fun mostly. I have a server machine ("rebus") that
serves a few diskless clients (also virtual machines).
There is a slight problem rebooting the server. Since I'm NFS-mounting
/home from rebus:/export/home on the diskless clients *and* on the
"rebus" server itself, the server hangs if I'm rebooting using "doas
reboot" (or shutdown) as a user.
The reboot process seems to be hanging in a "nfsrcvl" state. The user's
shell, ksh93, seems to be hanging around too (root can see it in "top",
its state is "netio"), even though the user has been kicked out (was
logged in over SSH).
This does not happen if I reboot as root, with no other user logged in.
(I also get "reboot: revoke: Inappropriate ioctl for device", regardless
of who does the reboot.)
Would it be smarter to have /home as a symlink to /export/home on the
server? ... or NFS mount using -i? What do others do?
/etc/export:
/export -alldirs -maproot=root internal-netgroup
/etc/netgroup:
internal-netgroup \
(rebus, root, internal) \
(ewok01, root, internal) \
