[Gluster-users] Gluster/NFS mount issues

[Ben Turner]

Normally when I see this the NICs are not fully initialized.  I have done a couple different things to work around this:

-Try adding the linkdelay parameter to the ifcfg script:

LINKDELAY=time
where time is the number of seconds to wait for link negotiation before configuring the device.

-Try turning on portfast on your switch to speed up negotiation.

-Try putting a sleep in your init scripts just before it goes to mount your fstab items

-Try putting the mount command in rc.local or whatever is the last thing your system does before it boots.

Last time I looked at the _netdev code it only looked for an active link, it didn't ensure that the NIC was up and able to send traffic.  I would start with the linkdelay and go from there.  LMK how this works out for ya, I am not very well versed on the Ubuntu boot process :/
