The Matrix cluster is currently unavailable due to a problem with its data storage. |
12/2013: EZ-Backup data:
- Duration of backup: 60 minutes
- Total: 5.35 million files backed up, for a total of 1.57TB of data.
- This represents 52% compression (including versions?)
- Incremental backup.
- Most recent backup backed up 453K files, for a total of 5GB of data transferred.
Situation
See recovery project's punch list.
Update

Draft schedule, assuming no surprises
Now: Yi to run 2 different ~24 hour tests.

, Friday
- Matrix is now open to all researchers.
=> Researchers to confirm they have all their data from their clean-up. We recognize this may require running some test jobs. Do this as soon as possible!
Deadline for getting older files back is:
- Monday, 11/25 (but may be sooner if spare HDs needed earlier!): After this date, we will be unable to restore any data not on EZ-Backup.

- We tried copying the data from the Matrix disks to ChemIT disks to create a backup which resides independently from your hardware.
- However, when we arrived this morning, we found the copy did not complete (176GB of 3.1TB). And worse, we now can't can’t see much of the original data.
- We have called in additional expertise to further help characterize the problem, especially now that we can't can’t even see the original data.
