[Eisfair_dev] [eisfair-1] Frage zu nfsclient / nfsserver

[Ansgar Püster]

Hallo,

folgende Konfiguration

eisvirt1
--------
base     : 2.0.4
eiskernel: 2.2.0 (2.6.32-eisfair-1-SMP)

nfsclient¦printer-file¦1.1.12¦testing¦2012-10-26¦NFS client¦

/etc/config.d/nfsclient:
START_NFSCLIENT='yes'
NFSCLIENT_MOUNT_N='1'
NFSCLIENT_MOUNT_1_ACTIVE='yes'
NFSCLIENT_MOUNT_1_HOST='eisvirt2.ap.de'
NFSCLIENT_MOUNT_1_MOUNTPOINT='/vamos_share/log'
NFSCLIENT_MOUNT_1_DIRECTORY='/tomcat/log'
NFSCLIENT_MOUNT_1_OPTION='bg,retry=1

eisvirt1 # ls -lad /tomcat/log
drwxr-xr-x 2 root root 4096 May 15 20:08 /tomcat/log

eisvirt2
--------
base     : 2.0.4
eiskernel: 2.2.0 (2.6.32-eisfair-1-SMP)

¦nfsserver¦printer-file¦1.3.10¦testing¦2012-10-26¦NFS server¦

/etc/config.d/nfsserver:
START_NFSSERVER='yes'
NFSSERVER_SHARE_N='1'
NFSSERVER_SHARE_1_ACTIVE='yes'
NFSSERVER_SHARE_1_PATH='/vamos_share/log'
NFSSERVER_SHARE_1_HOSTS_N='1'
NFSSERVER_SHARE_1_HOSTS_1_HOST='192.168.1.71/24'
NFSSERVER_SHARE_1_HOSTS_1_RW='yes'
NFSSERVER_SHARE_1_HOSTS_1_ANONUSER='root'
NFSSERVER_SHARE_1_HOSTS_1_ANONGROUP='root'
NFSSERVER_SHARE_1_HOSTS_1_ROOT_SQUASH='yes'
NFSSERVER_SHARE_1_HOSTS_1_ALL_SQUASH='yes'

eisvirt2 # ls -lad /vamos_share/log
drwxr-xr-x 2 root root 4096 May 15 20:08 /vamos_share/log

Startmeldung, wenn NFS-Server aktiv:

eisvirt1 # /etc/init.d/nfsclient start
Starting NFSclient ...
- portmap ...
- rpc.statd ...
- mounting eisvirt2.ap.de:/vamos_share/log as /tomcat/log ...
   mount.nfs: text-based options: 'bg,retry=1,addr=192.168.1.72'
   eisvirt2.ap.de:/vamos_share/log on /tomcat/log type nfs (rw,bg,retry=1)

=> alles O.K.

Startmeldung, wenn NFS-Server _nicht_ aktiv:

eisvirt1 # time /etc/init.d/nfsclient start
Starting NFSclient ...
- portmap ...
- rpc.statd ...
- mounting eisvirt2.ap.de:/vamos_share/log as /tomcat/log ...
mount.nfs: internal error
   mount.nfs: text-based options: 'bg,retry=1,addr=192.168.1.72'

real    1m1.447s
user    0m0.528s
sys     0m0.968s

Also Fehler nach ca. 1 Minute.

Commands, via ps -eaf sichtbar:
mount -v -t nfs -o bg,retry=1 eisvirt2.ap.de:/vamos_share/log /tomcat/log
/sbin/mount.nfs eisvirt2.ap.de:/vamos_share/log /tomcat/log -v -o 
rw,bg,retry=1

Gem.
	http://linux.die.net/man/5/nfs
hätte ich folgendes erwartet:

If the bg option is specified, a timeout or failure causes the mount(8)
command to fork a child which continues to attempt to mount the export.
The parent immediately returns with a zero exit code. This is known as
a "background" mount.

Der fehlerhafte mount sollte also wegen bg sofort terminieren.

Nach Start des NFS-Servers auf eisvirt2 sollte dann "später" ein
erfolgreicher mount geschehen. Das klappt nicht.

Was läuft falsch?
Was ist falsch konfiguriert?

Danke für eure Hilfe.
