[gentoo-user] URGENT: nfs stopped working

[Michael Sullivan]

OK.  I recently switched my three computers (carter, camille, and
catherine) to the new gcc profile:  i686-pc-linux-gnu-4.4.5 from
i686-pc-linux-gnu-4.3.4.  As recommended, I performed emerge -e system
and then emerge -e world on all of them.  Carter finished his emerge -e
world a couple of days ago (he's faster than the others).  Camille and
catherine were a few hundred packages from the end of their emerge -e
world when the power went out.  Carter supplies daily
updated /usr/portage to camille and catherine via nfs, but when I
restarted the computers when the power came back on, I get this:

camille ~ # mount carter:/usr/portage /usr/portage/
mount.nfs: an incorrect mount option was specified

Am I not constructing my command correctly?

I have tried mount -t nfs and it still doesn't work.  I can ping carter
fine, and carter says nfs is running.  How do I get nfs back?

The same on both systems? The other one doesn't have v4 set?

Did you try modprobing NFS before trying your mount command?

Unless you don't know what modprobe is, I shouldn't have had to ask this. You should have replied with `lsmod | grep -i nfs` (showing that the module is loaded) and a second attempt to perform the NFS mount.

If one has no V4 you'll have to use V3, so add vers=3 to your mount options.

I rebuilt kernels on camille and catherine, enabling every NFS option I
could and now they both can use NFS from carter.  However, carter cannot
mount camille's /mnt/store:

carter ~ # mount camille:/mnt/store/ /mnt/store/
mount.nfs: requested NFS version or transport protocol is not supported

But, somehow, carter has access to all the recordings.  This happens
sometimes and I don't know why...

I use nfs about twice/year to transfer large files between machines -- so
I'm quite an expert at praying to the computer gods to "please let this nfs
mount work just this one last time and I'll never bother you again, I promise!"

I'm lying, of course, because I intend to do it again six months from now.

Every time, the computer gods make me suffer through multiple attempts to
guess the correct magic prayer before the remote nfs filesystem finally
appears for its biannual visit on /mnt/nfs.

Yes, I may well be paranoid, but it seems to me that the magic prayer for
nfs mounts changes every time I need it.

Sometimes I succeed using mount.nfs4, sometimes using mount -t nfs -o
nfsvers=4, or sometimes just mount -t nfs.

I have NFI what the real secret is, so I ask you nfs wonks to have mercy
and fill us in...

Why not just use scp of sftp since its so infrequent?

scp is fucking easy to do. Even easier: pure-ftpd.

Yea, like using hal.  lol  I used scp a few times.  Figuring out how to 
get it to work was like pulling teeth.

It did work once I got it figured out.

There's not much else simpler than scp! I should have added a smiley to my
comment about smaller can or worms - NFS is not complicated either.

I use scp all the time -- but It's The Principle Of The Thing(TM) :p

I never had any trouble with NFS until version 4 came along, and nothing *but*
trouble since then.

I figure if I invoke mount.nfs4, I shouldn't need to include the nfsvers=4
option in addition -- but that's what it has made me do.

At least until the last time I tried it about two weeks ago, when plain old
mount -t nfs seemed to work without any magic incantations.  OTOH, I didn't
bother to investigate which nfs version actually connected.  I just gave thanks
for the crumbs it tossed me and copied my files across ;)

OTOH sftp really is quite nifty...
