Hi Roland,
Thank you for that tip, and it worked perfectly. I had indeed been editing the images using the '-s' option, noticed the changes were overwritten upon update, and just remembered to make the changes again afterwards. Of course that's not a sustainable mode of operation, as problems typically arise somewhere between my keyboard and my chair.
I've got another question for you, related to this one. No matter what I've tried, I can't seem to get my <headnode>:/srv/data folder network FS mounted to /data on my diskless compute nodes using the Qluman-GUI. Same with <headnode>:/srv/apps to /apps. I've confirmed that the Network FS Mounts take export paths /srv/data and /srv/apps mapped to Mountpoints /data and /apps via NFS, and that in my Filesystem Exports I have /srv/data and /srv/apps listed as Export Paths on both my IB and Boot networks (I've got an Infiniband switch and a Gigabit one too) from my headnode Server (beosrv-c).
I've also confirmed that they do show up in /etc/exports on my headnode.
My permanent, sloppy fix has been to add nfs mountpoint entries to the /etc/fstab file in my Qlustar image using the editing mode mentioned above, and while this does work perfectly, I realize that if my headnode IP address were to change to something else this file would also need to be changed to reflect that.
Is anyone able to reproduce this issue using a headnode with only diskless nodes?
I'd be happy to upload any relevant Qluman config files if it would help.
Thanks as always, -Mike
