NFS Server nach Umzug in anderes Subnet
Hi, ich habe gestern meinen NFS Server aus dem 10.0.0.0/24 Netz in das 10.0.1.0/24 Netz verschoben. Jetzt kann kein Client mehr die Shares mounten: So siehts auf dem Server aus: Code:
storage:~# cat /etc/exports | grep -v ^#
/srv/archive/iso *(rw,async,no_root_squash,no_subtree_check)
storage:~# exportfs -v
/srv/archive/iso
<world>(rw,async,wdelay,no_root_squash,no_subtree_check)
storage:~# netstat -tulpen

"peername failed" zeigt zumeist auf, dass eine Timeout auftritt, wodurch die Verbindung getrennt wird. Ist für den Portmapper auch UDP offen? Was sagt 'rpcinfo -p' auf dem Storage? Kann der Client die gleichen Informationen mittels rpcinfo abfragen?

Hi,
UDP ports hab ich mitgepostet. 111 ist offen auf dem storage. rpcinfo sieht gleich aus: Code:
storage:~# rpcinfo -p

Die exports (die config ) zu sehen koennte u.U. hilfreich sein.
