I should mention that we set the osimage for nodes via groups, not

Regarding Rocks clusters, permit me to vent a little.
In my last employ we provided Rocks clusters Rocks is firmly embedded
in the Redhat 6 era with out of date 2.6 kernels.
It uses kickstart for installations (which is OK). However with modern
generations of Intel processors you get a warning

Sanger made a similar separation with our FAI-based Ubuntu deployments. The
FAI part of the installation was kept as minimal as possible, with the task
purely of partitioning and formatting the hard disk of the machine, determining
the appropriate network card configuration, and unpacking a min

Aren't the drives in the RAID hot-swappable? Removing the defective drive
and installing a new one certainly cycled power on those two? But I'm weak
at hardware, and have never knowingly relied on firmware on a disk.

Without a power cycle updating the drive firmware would be the only method
of tricking the drives into a power-cycle. Obviously very risky. A reboot
should be low risk.

David, I have never been in that situation. However I have configured my
fair share of LSI controllers so I share your pain!
(I reserve my real tears for device mapper RAID).
How about a mount -o remount Did you try that before rebooting?
I am no expert here - in the past when I have had non-R

Sure am!
Re scale, I can't speak to that because we just don't have that size. But
Ansible has been bought/absorbed into Redhat now, so the Ansible Tower
infrastructure may scale. You would need to test :)
