 Posted: Sat Jun 30, 2007 12:13 am Post subject: [NFS & distfiles] partager le repertoire distfiles |
 |
|
Bonsoir, simple test non fructueux....
J'ai créé un repertoire "distfiles" sur mon serveur... je l'ai monté via NFS et ... ben emerge veut pas. Pourtant, en root, j'arrive à ecrire sans problème  , mais emerge passe plus... J'ai vidé le répértoire (sur mon pc) avant mais rien à faire...
| Code: |
loop distfiles # mount
/dev/sda1 on / type reiserfs (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw,nosuid,noexec)
/dev/sda3 on /mnt/data type reiserfs (rw)
none on /dev/shm type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
10.2.1.62:/mnt/data on /mnt/serveur/data type nfs (rw,tcp,addr=10.2.1.62,addr=10.2.1.62)
10.2.1.62:/mnt/data2 on /mnt/serveur/data2 type nfs (rw,tcp,addr=10.2.1.62,addr=10.2.1.62)
10.2.1.62:/mnt/data3/distfiles on /usr/portage/distfiles type nfs (rw,tcp,addr=10.2.1.62,addr=10.2.1.62)
10.2.1.62:/mnt/data3/ on /mnt/serveur/data3 type nfs (rw,tcp,addr=10.2.1.62,addr=10.2.1.62)

Une idée ?
J'ai ceci lors du redémarrage du service sur le serveur (depuis une mise à our je pense):

t'arrives à ecrire dans le répertoire en root depuis le client ? et en user simple ?
(dans ton log j'ai l'impression que tu écris dans distfiles en root depuis le serveur)
Si t'arrives pas en root mais en user oui, c'est ptet une affaire de no_root_squash à mettre dans tes options du /etc/exports
Fais aussi gaffe à ce que les uid/gid matchent entre le serveur et le client pour les gens qui écrivent dessus. |

Sur le serveur (AMD64): | Code: | # cat /etc/exports
# /etc/exports: NFS file systems being exported. See exports(5).
/misc/distfiles 10.0.0.0/24(rw,async,no_root_squash,no_subtree_check) |
Sur les clients (x86,mips.ppc,hppa,sparc,alpha): | Code: | $ grep distfiles /etc/fstab
polly:/misc/distfiles /usr/portage/distfiles nfs rw,nolock,noatime,rsize=8192,wsize=8192 0 0
$ mount|grep dist
polly:/misc/distfiles on /usr/portage/distfiles type nfs (rw,noatime,nolock,rsize=8192,wsize=8192,addr=10.0.0.3) |

+1 tout plein.
C'est le grand classique avec NFS.

+1 ceci dit j'ai abandonné le nfs pour portage .. trop de ralentissements aléatoires (suis en gigabit pourtant) ..
Maintenant j'ai pas trop forcé car la solution a été le raid0x6 pour mon desktop donc ^^ |
