 Posted: Thu Sep 08, 2005 3:03 pm Post subject: NFS Daemon refuses to start with post-2.6.13-mm sources |
 |
|
It's all in the title - 2.6.13-rcX-mmX work fine, but with 2.6.13-mm1 and mm2 I get this:
| Code: | jordan@jordan jordan $ sudo /etc/init.d/nfs start
* Mounting RPC pipefs ... [ ok ]
* Starting idmapd ...
rpc.idmapd: Skipping configuration file "/etc/idmapd.conf": No such file or directory [ ok ]
* Starting NFS statd ... [ ok ]
* Exporting NFS directories ... [ ok ]
* Starting NFS daemon ...
* Error starting NFS daemon [ !! ]
* Starting NFS mountd ... [ ok ]
|
the only thing i get in dmesg is this:
| Code: | NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory
NFSD: starting 90-second grace period |
which is the same whether i'm running a working kernel or not.
| Code: | jordan@jordan linux $ cat .config | grep NFS
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V3_ACL is not set
CONFIG_NFS_V4=y
# CONFIG_NFS_DIRECTIO is not set
CONFIG_NFSD=y
CONFIG_NFSD_V3=y
# CONFIG_NFSD_V3_ACL is not set
CONFIG_NFSD_V4=y
CONFIG_NFSD_TCP=y
CONFIG_NFS_COMMON=y |
any help on where to look for info on why this is happening... would be greatly appreciated. anyone else not having this problem with mm kernels? |

Hi.
This is just a "me too" post. Running the (kernel) NFSD server with 2.6.13-mm1 also does not work here.
The client seems to be fine.
So far I tried "strace rpc.nfsd" which shows it breaks while trying to write to "/proc/fs/nfs/threads" ( Gives a "permission denied" error, although the file comes up as "-rw" for root ). This also happens when I try "echo "8" > /proc/fs/nfs/threads".
In the log files I found the message "connect from unprivileged port" (or something like that back to 2.6.12-mm2 for now), googling that only gives some old lkml posts form 2002/2003 with kernel 2.4.(18 /19 ) where the problem came up before. That is where I got the "echo "8" ..." stuff form, as rpc.nfsd does not seem to do much else.
I couldn't solve it so I'm back on kernel-2.6.12-mm2.
(edit my english is horrible, sorry!) |

Yet anoter "me too"; this time running gentoo-sources-2.6.13
.config
| Code: | nexus ~ # cat /usr/src/linux/.config | grep -i nfs
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_NFS_V3_ACL=y
CONFIG_NFS_V4=y
# CONFIG_NFS_DIRECTIO is not set
CONFIG_NFSD=y
CONFIG_NFSD_V2_ACL=y
CONFIG_NFSD_V3=y
CONFIG_NFSD_V3_ACL=y
CONFIG_NFSD_V4=y
CONFIG_NFSD_TCP=y
CONFIG_NFS_ACL_SUPPORT=y
CONFIG_NFS_COMMON=y
|
This shows that I have everything including nfsv4; except DirectIO enabled for NFS; and built in.
| Code: | nexus ~ # cat /var/log/messages
Sep 8 14:54:14 nexus rpc.statd[13873]: Version 1.0.7 Starting
Sep 8 14:54:14 nexus nfsd[13883]: nfssvc: Function not implemented
Sep 8 14:54:14 nexus rc-scripts: Error starting NFS daemon
|
Applicable lines from my logs.
and this is what apparently starts when I try and run the service:
| Code: | nexus ~ # ps -aux | grep -i rpc
rpc 12491 0.0 0.3 1736 648 ? Ss 05:11 0:00 /sbin/portmap
nobody 13873 0.0 0.4 1672 776 ? Ss 14:54 0:00 /sbin/rpc.statd
root 13889 0.0 0.3 1716 720 ? Ss 14:54 0:00 /usr/sbin/rpc.mountd
|
From my googling and searching the forums, it seems as though the error reported in /var/log/messages about nfssvc not being implimented was signaling that the server daemon wasn't compiled with the kernel (either as a module or built in) but it seems as though that isn't the case with us.
SHAN EDIT: For snits and giggles I removed nfsv4 support from my servers kernel and recompiled and for some reason it works. Seems as though this is only a nfsv4 issue. Then again maybe its because I (we?) are trying to compile both nfsv3 and v4 server support in at once; but using make menuconfig with g-s atleast; doesn't allow me to just select v4.

Ok. I've tried compiling the kernel again. This time quite "basic":
- nfs compiled in
- no "direct IO" support
- only version 3
| Code: |
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V3_ACL is not set
# CONFIG_NFS_V4 is not set
# CONFIG_NFS_DIRECTIO is not set
CONFIG_NFSD=y
CONFIG_NFSD_V3=y
# CONFIG_NFSD_V3_ACL is not set
# CONFIG_NFSD_V4 is not set
# CONFIG_NFSD_TCP is not set
CONFIG_NFS_COMMON=y
|
"/etc/init.d/nfs start" still breaks with these errors:
| Code: |
[portmap] connect from 127.0.0.1 to set(nfs): request from unprivileged port
[nfsd] nfssvc: Permission denied
|
and strace gives:
| Code: |
strace rpc.nfsd:
(... lots of stuff ... )
open("/proc/fs/nfsd/threads", O_WRONLY) = 3
write(3, "1\n", 2) = -1 EACCES (Permission denied)
|
Trying
| Code: |
echo "1" > /proc/fs/nfsd/threads
|
(thats what rpc.nfsd is basically trying to do...)
doesn't work either.
Emerging new nfs-utils also did not help.
Any more suggestions?
(edit: works with vanilla 2.6.13, so back to 2.6.12-mm2 for now) |

anyone found out why this is happening yet? i want to test out 2.6.14-rc1-mm1 and i'm tired of 2.6.13-rc6-mm2.
i tried compiling without nfsv4, but no success.
is this a specific kernel problem and therefore distro independent, or something specific to gentoo? |

This is a Linux kernel problem. The port that the linux kernel uses for portmap has changed and it screws up some things. There's already a patch out for it. Released after the 2.6.14-rc2-mm1 sadly, so hopefully it will make it into the next release. Or whoever is making the mm-sources releases could be kind enough to include it in the ebuild. I have no idea who to talk to about this though.
I hope that helps anyone still having difficulties

I was also having problems with 2.6.13-whatever, hoped 2.6.14 was cured. guess not |

I think I butch'd my ypdomain too trying to fix it. Just when I get a brand new laptop.
Thought I googled past something that said ports needed to be under 1024, which is ridiculous, says the ports unprivledged though. |
