Murphy's law:

• r730data6, which serve home for phys, psmn, cbp… and Xnfs for physic's groups, has crashed around noon.

EDIT: back online.

• r720data4 (craldb, phoenix) is in read-only mode for craldb data (too many disks with errors)

• r730data7, which serve bio's data has crashed too. EDIT: back online.
