 Posted: Sun Apr 26, 2015 4:47 am Post subject: NFS portage and distfiles NOT working? |
 |
|
Okay, this is truly odd. My setup is that my 'server' has no direct internet access or portage tree. It doesn't need it for its function of running programs in the background.
In order to keep it up to date and avoid over-syncing it shares my desktop's /usr/portage over NFS.
This is where the problem is. I want to emerge sys-apps/portage-2.2.18 before anything else. I emerge it like normal, but it insists it must download the package. However, the package exists in /usr/portage/distfiles/portage-2.2.18.tar.bz2, exactly where it is supposed to. The current portage is sys-apps/portage-2.2.8-r2. Clearly, it shouldn't do this. I can see the file, I can touch the file, but I can't emerge the package.
It looks like it has the right permissions -rw-rw-r-- 1 portage portage 942561 Apr 25 21:37 /usr/portage/distfiles/portage-2.2.18.tar.bz2
And I can emerge some other packages, eudev for example, which just confuses me more.
My exports file | Code: | # /etc/exports: NFS file systems being exported. See exports(5).
/export 192.168.2.0/24(rw,fsid=0,no_subtree_check)
/export/portage 192.168.2.0/24(rw,nohide,insecure,no_subtree_check,no_root_squash) |
I'd be happy to post anything else that is needed.
EDIT: Looks like a clock sync problem between the two boxes.
EDIT2: Nope, must be something else.

It works fine for me. I'm using a tiny raspberry pi as a gigantic fileserver 
All other systems share distfiles, portage, linux-source.
On "server":
/etc/exports/ | Code: | # /etc/exports: NFS file systems being exported. See exports(5).
/export *(rw,fsid=0,no_subtree_check)
/export/distfiles *(rw,nohide,insecure,no_subtree_check,no_root_squash)
/export/portage *(rw,nohide,insecure,no_subtree_check,no_root_squash)
/export/linux-src *(rw,nohide,insecure,no_subtree_check,no_root_squash)
/export/transfer *(rw,nohide,insecure,no_subtree_check,no_root_squash) |
/etc/fstab | Code: | /sda2/linux-src /export/linux-src auto bind 0 0
/sda2/distfiles /export/distfiles auto bind 0 0
/sda2/portage /export/portage auto bind 0 0
/sda2/transfer /export/transfer auto bind 0 0 |
On "clients":
/etc/fstab | Code: | 192.168.1.2:/ /sdb2 nfs4 rw,noatime 0 0
/sdb2/linux-src /usr/src nfs bind 0 0 |
/etc/portage/make.conf | Code: | DISTDIR="/sdb2/distfiles"
PORTDIR="/sdb2/portage"
PKGDIR="/sdb2/transfer/bindist64" |
Server's vixie-cron runs "emerge --sync" every morning for me, but it can also be run from any client.
Test on server: | Code: | rm /sdb2/distfiles/portage-2.2.18.tar.bz2
emerge portage
ls -l /sdb2/distfiles/portage-2.2.18.tar.bz2
-rw-rw-r-- 1 portage portage 942561 Mar 4 21:13 /sdb2/distfiles/portage-2.2.18.tar.bz2 |

The Doctor,
Permissions on the file?

is that portage tree over NFS actually mounted over local /usr/portage?
You surely have some older version.
Also, do you keep distfiles on the same filesystem that stores your /usr/portage? NFS ignores mountpoints, so separating those requires another line in exports. |

Thanks for the thoughts.
@toralf
No error message. It just tries to download the package without a working internet connection. It shouldn't because the right package is there with the right permissions.
My desktop sees the file as being perfectly valid.
@NeddySeagoon
portage portage, as I believe it should be. I checked and my desktop and server both see the file as having the same permissions and it works from the desktop.
| Code: | ls -l /usr/portage/distfiles/portage-2.2.18.tar.bz2
-rw-rw-r-- 1 portage portage 942561 Apr 25 21:37 /usr/portage/distfiles/portage-2.2.18.tar.bz |
@szatox
The server doesn't have anything at /usr/portage, just a mount point. My desktop exports the entire contents of /usr/portage which includes the portage tree, distfiles, and packages.
Which actually lead to an interesting conclusion. I could emerge the binary version of portage and a few other packages, but that seems to have broken sshd...

@Jaglover Yes, you are quite right. Normally I would have, but tired and not thinking leads to mistakes. Fortunetly, the two cpus are almost identical. I don't think it did any real harm.
@toralf
Yes, the DISTDIR points to the right place. Like I said, I could emerge eudev (which was an old file) but the newly downloaded portage didn't work.
Thinking on that, is it possible that clock skew is to blame here? I would have thought that if that was the case touching the file would solve that problem.

It looks like a clock problem. The dates match within a minute, but still no joy with new packages, but the older ones are working. I'll get openntpd working and hopefully that will get this gremlin. I'll mark this as solved.

hello,
anybody know whether NFS can have different root folders?
It make sense to have a root folder for something specific fsid=0.
But what if some different to share such as torrents? Can it be used fsid=1?
The fsid=0 concept is confusing.
thanks |

It doesn't seem to be a clock problem. I have the times within a few seconds but portage still won't use the newer packages in the distfiles. It just tries to download them over again.
I let the packages sit for over 12 hours. This is getting really annoying.

If old files work and new ones don't it has to be permissions.
Do you have FEATURES=userfetch now and didn't before?
Is portage the same userID on both boxes. Its IDs that matter over NFS, not usernames.

I wish it where that simple. On my desktop | Code: | ls -l /usr/portage/distfiles/openntpd-5.7p3.tar.gz && id portage
-rw-rw-r-- 1 portage portage 409734 Apr 27 13:32 /usr/portage/distfiles/openntpd-5.7p3.tar.gz
uid=250(portage) gid=250(portage) groups=250(portage)
|
On my server | Code: | ls -l /usr/portage/distfiles/openntpd-5.7p3.tar.gz && id portage
-rw-rw-r-- 1 portage portage 409734 Apr 27 13:32 /usr/portage/distfiles/openntpd-5.7p3.tar.gz
uid=250(portage) gid=250(portage) groups=250(portage) |
I have never had FEATURES=userfetch
EDIT:corrected partial info
