Lens studio keeps crashing6/2/2023 Postoffices 9 and 10 were up and running Monday afternoon but failed again Monday evening. The damage varied across the disk arrays, so some "postoffices" that house individual mailboxes (actually the equivalent of folders in the storage system) were affected more than others. A reboot when reading and writing operations are in progress can result in damage. Cornell followed the instructions, MacDonald said.ĭespite this, on the 994th day of continuous operation - June 15 - the arrays rebooted anyway. Sun supplied instructions for correcting the problem. While details are still to come from Sun Microsystems, the supplier of the disk arrays, there is a known bug in the hardware that causes the storage arrays to spontaneously reboot (i.e., abruptly shut down and restart) on the 994th day of operation, according to Rick MacDonald, director of systems and operations for CIT. This may also be affecting some of the Mail servers." Eventually it developed that eight arrays of hard disks holding the "mailboxes" in which each user's incoming mail is stored had failed. on June 15: "A service affecting issue with SAN (Storage Area Network) is currently under investigation. The first sign of a problem was a rather innocuous message from the Network Operations Center at 12:22 p.m. "You cannot pay people enough to have this kind of dedication to their work and Cornell," she said. Many CIT staffers, she said, literally worked around the clock, sleeping on campus, until the job was done. She thanked IT staff for their work in repairing the system and helping those affected by the outage. ![]() McClure promised a review of the incident to plan how to minimize the probability of a recurrence and prepare for more effective recovery. ![]() "I'm not sure any of us fully anticipated how debilitating this outage would be, but it is clear that we cannot tolerate the loss of what has become our main communication channel," said Polley McClure, vice president for information technologies, in a statement posted on the CIT Web site. Some incoming mail was irretrievably lost in the process, according to Cornell Information Technologies (CIT) technicians. A major hardware crash Sunday, June 15, left many Cornell users unable to receive e-mail for periods ranging from two days to almost a week.
