Re: vfsx17.patch available - continuing vfs work (expert develop
:I'm running make -j100 buildworld with /usr/obj NFS-lookback mounted
:from /home/nfs to see if it survives (the previous one didn't finish).
:I'll run other benchmarks on that mount point if it's finished.

:One thing I noticed is that, with the following line in /etc/exports
:/home/nfs 127.0.0.1
:
:(and is mounted to /usr/obj) one would usually get `permision denied'
:(unless you specified one of -map* options) if you for example try to create
:a file on the NFS mounted filesystem as root; with vfsx17.patch, it creates
:a file with uid = 4294967296 instead. Is this normal?
Yes. You have to export and allow root permissions (or some other user
id), or the nfs server will map everything to 'nobody'. e.g.:
/home -maproot=root: ...
:And if I changed the directory permission on /home/nfs, the permission
:was not propagated to /usr/obj until I restarted mountd. I don't remember
:if the same thing happens on other systems, though.
The cache entries have a timeout. The timeout is dynamically calculated
based on how often the file is found to have changed but this whole area
has been shredded and pasted back together so I would not be surprised
if there were some issues DragonFly_Stable is probably even worse then
HEAD with regards to timeouts.
