Matrix currently unavailable due to a problem with its data storage.
As of 10/3/13, 3pm, ChemIT still hopes that no data that was on the data storage system has been irretrievably lost.

  • Since system could only accommodate a loss of 2 hard drives (of 6), we are now at high risk since 2 of the hard drives seemed to have failed.

Status

10/3/13, 2:45pm: 3TB hard drive approved by Harold Scheraga. ChemIT will order.

10/3/12, noonish: Using data on 4 hard disks, using RAID 6 to reconstitute data on 2 drives which test OK separately with a "quick" test.

Plan

Install new hard drive.

Analyze further one of the two suspected hard drives to try to isolate source of data corruption.

Notes

On 10/2/13 (Wed), Matrix became unavailable.

System has 2 hard drives for the OS. And 6 hard drives for the data storage.

OS hard drives seem fine.

However, the system refuses to work with all 6 hard drives. Can only get it to work with 4 of the hard drives, so initially suspecting a failure of two hard drives.
