[Bug 662711] Re: NFS user/group mapping not working in 10.10
This bug persists in Ubuntu 11.04 on amd64. The nfsv4 is absolutely not working, can anybody tell me why this terrible code is the default? Please remove this non-functional kernel server thing from the distribution, it doesn't work as it ought to. If nfsv4 isn't working, then what's the point of this package? I'll check again about NEED_IDMAPD, it's probably set on my system. I don't think it solves anything as Radu claims. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/662711 Title: NFS user/group mapping not working in 10.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/662711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

BTW, this is likely a 64-bit problem, as that number is -2, right? Maybe it's an exceptionally bad programming error. I guess I won't see this problem on i386. So, maybe there is a serious 64-bit bug, in this case, why is the nfs- user-server package removed from the distribution, why are the choices being limited despite the fact that this bug has not been solved for over a year? Or are you not testing these things on 64-bit machines? BTW, the claims that this can be fixed simply by changing the configuration seems to be wrong. The default config in 11.04 already turns on that non-working idmapd. This bug can be observed on a single machine running ubuntu 11.04 on amd64 currently.

It's not terrible code. NFSv4 works perfectly well if configured. Please remove this non-functional kernel server thing from the distribution, That's not a reasonable request by any measure. It's perfectly functional for many people - myself included. I'll check again about NEED_IDMAPD, it's probably set on my system. I don't know why you think it's probably set on your system. It wouldn't be set by default. If it *is* set on your system and you're experiencing problems, then you're seeing a different issue than this one. BTW, this is likely a 64-bit problem, as that number is -2, right? Maybe it's an exceptionally bad programming error. I guess I won't see this problem on i386. Incorrect. in this case, why is the nfs-user-server package removed from the distribution, Because that's a dead project with a variety of other deficiencies, and the Debian package maintainer requested its removal. why are the choices being limited despite the fact that this bug has not been solved for over a year? nfs-user-server was removed well before this bug became an issue. Or are you not testing these things on 64-bit machines? This has nothing to do with 32- vs 64-bit systems. (NFSv4 works fine here on 64-bit installs.) BTW, the claims that this can be fixed simply by changing the configuration seems to be wrong. The default config in 11.04 already turns on that non-working idmapd. idmapd is turned on by default only on servers, and on clients which specify nfs4 as a filesystem type in /etc/fstab. Because mount.nfs now negotiates NFSv4 first if available, this is no longer the correct default behavior; we should instead start idmapd unconditionally. So this is definitely a bug - but it's also one for which there is a trivial workaround. Either edit /etc/default/nfs-common to start idmapd, or if your server advertises NFSv4 but is not configured to do id mapping correctly, use nfsvers=3 in your mount options. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

[Bug 662711] Re: NFS user/group mapping not working in 10.10
I only accidentally found this bug using Ubuntu 11.04 pre-installed daily build 20110409 for ARM on a Pandaboard. All my 10.10 i386 machines work fine, but now that I checked, they're actually not fine, so it was just luck that it didn't cause me any trouble. Setting NEED_IDMAPD=yes fixes the problem on the Pandaboard and on my i386 machines. Without that option, start idmapd will give me a PID, but when I check with ps there's no rpc.idmapd around. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/662711 Title: NFS user/group mapping not working in 10.10 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 662711] Re: NFS user/group mapping not working in 10.10
We have the problem, that the nfs-server is externally hosted and NFS entries are published via automounter maps. Running now 10.10 on an NFS client we have the situation: * mount uses NFS4 per default * autmounter maps don't give something like vers=3 = nfs stuff is mounted nobody/nogroup The only solution I tested successfully so far is to manually mount the things with: mount ... vers=3 ... Another solution, I'm thinking about is to replace /sbin/mount.nfs which is now /sbin/mount.nfs4 really with an version mount version 3 per default. But that's ugly! Is there something I miss here? Can I configure a default for mount?

This morning, I had a working NFS set-up on an 10.04 server with 10.10 clients. After upgrading the server to 10.10, I had this problem as well. Setting NEED_STATD=no and NEED_IDMAPD=yes on BOTH ends fixes it, indeed. Thanks a lot for the info! And... yes! I would have appreciated a default configuration that would have worked 'out of the box' (or at least some warning that things have changed and what to do - which would have saved me a few hours).

@Perry: Thanks, from your suggestion I made the changes to /etc/default/nfs- common and started idmapd, and the problem was resolved. @Tiemen: Thanks for the link, but even the wiki authors seem confused about this issue... So, now it seems clear that it is a default configuration problem rather than a bug. I suggest this bug report should stand as a request to change the default configuration.

[Bug 662711] Re: NFS user/group mapping not working in 10.10
Not a bug it seems, but needs documentation or something somewhere. 10.10 enables NFSv4 and I was able to fix it by enabling nfs idmap on both server and client. On my solaris server, I edited /etc/default/nfs and set NFSMAPID_DOMAIN to my server's name (domain name, whatever), then did svcadm restart nfs/mapid On ubuntu, I edited /etc/idmapd.conf and changed Domain to be the same value as what I set for NFSMAPID_DOMAIN, edit /etc/default/nfs-common and set NEED_STATD=no and NEED_IDMAPD=yes, then service rpc_pipefs restart and service idmapd restart, remount your nfs shares (in my case, service autofs restart); and all the uid/gid mapping should now be correct. -- NFS user/group mapping not working in 10.10 https://bugs.launchpad.net/bugs/662711 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

same problem here, client 10.10 and server 10.10 gives me UID and GID 4294967294. UID and GID are correct on the server but not on the client. It works however if i connect an ubuntu 10.04 client to the 10.10 server. So it seems to be a client issue.

Solaris servers, ubuntu 10.10 clients. This used to work fine. Exact same problem as the one above: However now the client is always displaying 4294967294 for the UID and GID but - and here is the strange bit - if I create a file on the client it shows up on the server with the correct user and group (but on the client still with 4294967294).

[Bug 662711] Re: NFS user/group mapping not working in 10.10
I can confirm this bug for our mixed environment (Solaris servers using zfs, and Ubuntu clients). It does seriously affect us, since the behaviour of file creation is quite erratic (as far as I can see). Additional observations: 1. No problems with older Solaris servers running NFS3 and NFS2 - seems to be specific to NFS4. 2. Creating dir on NFS4 share from Ubuntu 10.10: ubuntu1010 md test; ls -l drwxrwx--- 2 4294967294 4294967294 3 2010-10-20 09:00 test This shows up correctly on Solaris boxes and Ubuntu 10.04 mounting the same share: drwxrwx--- 2 martin staff 2 2010-10-20 09:00 test 3. If I change ownership on Ubuntu 10.10, strange things occur: ubuntu1010 chown martin:staff test; ls -l drwxrwx--- 2 martin staff 3 2010-10-20 09:00 test ubuntu1010 cd test bash: cd: test: Permission denied -- This is really annoying! Meanwhile, on the other machines: ubuntu1004 ls -l drwxrwx--- 2 4294967294 4294967294 3 2010-10-20 09:00 test solaris ls -l drwxrwx--- 2 nobody nobody 3 2010-10-20 09:00 test So, apparently my user info does not get transmitted to the server either, which makes changing permissions extremely hazardous.
