 |
|
Hello,
I have been working with Gentoo Diskless nodes for a while, and I'd like to thank everyone who made it possible.
It has been a while since I configured a diskless server, so today I was stumped for a few hours on an issue I know I solved before.
Basically, extra directories like /usr were defined in /etc/fstab but were not mounting on boot. mount-a had no problem performing the mount after logging in.
I altered the netmount script, which alleges that it cannot handle NFS mounts properly. However after the modification it yields proper mounts with no errors (No visible ones anyway).
The modification was to remove the "-O _netdev" option from the mount arguments.
I don't know if this is proper, however it seems to work.  I also recalled (after rediscovering it) that this is how I resolved the issue months ago. The systems were always stable.
I tried to use the nfsmount script, however it complained that rpc.statd would not start, and I could not find any debug output in dmesg or /var/log.
The arguments can be found on lines 34 and 80.
EDIT : removing the arguments from line 80 creates the usual "Device is Busy" Warning on a diskless system. Leaving the options in place shuts it up.
