Hello again,
The maintenance has concluded successfully within the designated, and
the Tool Labs instance now use the new NFS server for shared filesystems.
This doubled as a hard test of the continuous bot start/restart system,
since the entire cluster was disabled for rolling periods during the
maintenance, and the filesystem on which the actual tools were running
has been switch underneath them -- pretty much a worst case scenario to
recover from.
The result is that all but one tool that had been started as a
continuous process restarted cleanly and automatically as the cluster
returned to function with the new filesystem (the tool that did not
failed to return for an unrelated reason).
Thank you all for your patience!
