The disk array rebuild has completed. Some nodes were being brought up during the rebuild to help take some jobs, but now all should be online.

UPDATED: Cygnus/Force: Second failure of new VM Storage (FIXED)
————————————————————
UPDATE: At 8:45pm EDT, Force resumed normal function. The normal computing environment is now restored.
————————————————————
UPDATE: At 7:35pm EDT, Cygnus resumed normal function. Force is still under repair.
————————————————————
5:30pm:
Well folks, I hate to do this to you again, but it looks like I need
to take cygnus and force down again thanks to problems with the storage.
Again, I’ll down Cygnus & Force at 7pm EDT. Please begin the process
of saving your work.
At this point, I’m moving these back to the old storage system, which,
while slow (and it did impact the responsiveness of these machines) at
least stayed running without issues. The new machine has not
previously shown issues in its prior use, so, I admit to being a bit
flummoxed as to what is going on.
This downtime will be longer as I need to scrub a few things clean,
make sure the VMs will be intact and usable.
I’ll let you know when things are back online. I don’t have good
estimates this time.
No scheduled compute jobs will be impacted.
I, and the rest of the PACE team apologize for the continued
interruption in service and we hope to rectify these issues in a
couple of hours from now.
Thanks for your patience.

UPDATE: Cygnus & FoRCE now back online.
The reboot immediately fixed issues with Cygnus.
FoRCE had a little extra work to be done, but it too is now online.
Thanks for the patience. Compute away!
Urgent: Cygnus & FoRCE head nodes reboot at 7pm due to Storage issues
Hey folks,
We suffered a temporary loss of connectivity to the backend storage
serving our VM farm earlier this afternoon. As such, several running
VMs moved their OS filesystems to a read-only state.
The filesystems on which your data is stored are fine, however.
Unfortunately, though, the head nodes for Cygnus and the FoRCE
clusters were affected, and judging by our previous experience with
this, we need to reboot these nodes soon. As such, we ask any
currently logged in users to please save their data now and logout.
We are scheduling a reboot of these systems at 7:00pm EDT. A few
minutes after that, the nodes should be available and fully functional.
No jobs have been, nor will be lost in this process.
We are sorry for the inconvenience, and plan to keep you up to date
with any further issues with these, as well as the rest of the machines.
Maintenance Day Has Begun (All Clusters are Down)
As scheduled, the compute clusters have been brought down for maintenance activities.
Some of the work now progressing:
- Network redundancy changes
- Filesystem moves
- Updates to critical systems
- Change to directory services
We’ll let you know when we’re back and ready to compute.
