[lustre-discuss] trouble mounting after a tunefs

[Martin Hecht]

Hi John,

on the "Parameters" line the different nodes should not be separated by
":". Each node should be specified by a separate "mgsnode=..." or
"failover.node=..." statement. I'm not sure if separating the two
interfaces of each node by "," is correct here, or if this should be
splitted again in two separate statements.

best regards,
Martin
