[gentoo-user] emerge can't create lock in NFS exported distfiles directory

Hi!

As you can see, emerge (/usr/lib/portage/pym/portage_locks.py) failed
to create a lock file - or rather failed to lock the file.

On the client, I've got in make.conf:

DISTDIR="/Gentoo/Portage/distfiles"

alexander@blatt ~ $ ls -lad /Gentoo/Portage/distfiles /misc/distfiles /misc/distfiles/.locks
lrwxrwxrwx  1 root portage    15 22. Aug 09:43 /Gentoo/Portage/distfiles -> /misc/distfiles
drwxrwsr-x  4 root portage 16384 22. Aug 10:46 /misc/distfiles
drwxrwsr-x  2 root portage   125 22. Aug 10:46 /misc/distfiles/.locks

Normal files can be created just fine in $DISTDIR/.locks:

alexander@blatt ~ $ date > $DISTDIR/.locks/testfile.$(id -un)
alexander@blatt ~ $ date | sudo -u portage dd of=$DISTDIR/.locks/testfile.portage
0+1 Datensätze ein
0+1 Datensätze aus
alexander@blatt ~ $ date | sudo dd of=$DISTDIR/.locks/testfile.root
0+1 Datensätze ein
0+1 Datensätze aus
alexander@blatt ~ $ ls -la $DISTDIR/.locks
insgesamt 32
drwxrwsr-x  2 root      portage  4096 22. Aug 10:53 .
drwxrwsr-x  4 root      portage 16384 22. Aug 10:52 ..
-rw-r--r--  1 alexander portage    29 22. Aug 10:52 testfile.alexander
-rw-r--r--  1 portage   portage    29 22. Aug 10:53 testfile.portage
-rw-r--r--  1 root      portage    29 22. Aug 10:54 testfile.root

How can I use a NFS exported distfiles directory?

Thanks,

Try exporting the NFS share with the "no_root_squash" variable.


HTH,

It was already exported with no_root_squash - you might have
noticed, that the "testfile.root" was owned by root.

Here's the excert from exports:

/Gentoo/Portage/distfiles                       *.bei.digitalprojects.com(async,rw,no_root_squash)
/Gentoo/Notebook/Gentoo/Portage/packages        *.bei.digitalprojects.com(async,rw,no_root_squash)
/Gentoo/Notebook/var/lib/portage                *.bei.digitalprojects.com(async,rw,no_root_squash)

Hi,

this is part of my /etc/exports, where sleipnir is the name of the computer:

/usr/portage/ 
sleipnir(rw,sync,no_root_squash,nohide,no_subtree_check)

works fine here.

Add distlocks to FEATURES in make.conf

I already had distlocks in the FEATURES - must be some
default thing, as I did not add in the make.conf. Anyway,
I now added distlocks in make.conf - still no go :(

alexander@blatt ~ $ sudo emerge -vat app-text/txt2man

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild  N    ] app-text/txt2man-1.4.8-r1  11 kB

Total size of downloads: 11 kB

Do you want me to merge these packages? [Yes/No]

On the "server":

Why is portage failing to create a lock? (Answer: Because
it's not allow - "Permission denied". Q: Why is the permission
not granted? What to do, to grant the permission?)

Maybe this will give a clue?

# ls -ld /mnt/portage/distfiles/.locks/
drwxrwxr-x  2 root portage 72 Sep  1 11:34 /mnt/portage/distfiles/.locks/

My .locks directory is owned by the portage group, and group-writeable.

Not really :(

alexander@blatt ~ $ ls -ld /Gentoo/Portage/distfiles/.locks
drwxrwsr-x  2 root portage 6  1. Sep 18:01 /Gentoo/Portage/distfiles/.locks

Hm. Now all of a sudden, it works. Strange.

The only change was, that I rebooted "server".
