I've got a setup with a vserver acting as company webserver. The web contents come from the NAS via NFS.
I know I cant do any mounting inside the server without the CAP_SYS_ADMIN, which I dont want to use, as it encompasses too much. (also I got confused that the hostname didnt get set)
So I worked my way around this by mounting the www-content dierectory on the host-server (via the /etc/vservers/web01.sh script)
This worked up until today, when I changed the vserver's IPROOT to just include the IP-addresses of virtual devices (i.e. the IP-addresses assigned to eth0:1 eth0:2 and so on). When I had the vserver running and wanted to cd to the NFS-dir, the whole shell refused to work (no matter if that was inside the vserver's context or outside). Only way to get the shell working again was to stop the vserver, which did some nasty kill -9
Then I put an adress of a hardware network interface back into IPROOT and it worked fine again.
So that leaves me baffled with the two questions of why and how:
Why this behavior? How can I use an NFS-mount inside a vserver?
I thank you in advance for any ideas on this.
Kind regards, Mike Fischer
