cdsfs0 locked up, power cycled to restore the /ligo file system
Elli, Evan, Dave:
cdsfs0 (the /ligo file server) locked up this evening sometime after 18:43 PST. It was completely unresponsive, so Elli and Evan (with myself on the phone) power cycled the machine using the front panel button. It came back up with no problems and I was able to log into a control room workstation remotely. The system logs dont show any indication of the problem, it locked up silently. The attached logs show the last good log at 18:43 and the start of the reboot following power restoration at 19:17
Dec 29 18:43:58 cdsfs0 mountd[1623]: authenticated mount request from 10.22.0.141:1022 for /ligo (/ligo)
Dec 29 19:17:20 cdsfs0 kernel: imklog 4.2.0, log source = /proc/kmsg started.
I was not getting data at home from the external epics gateway, so I restarted this process. Also, I noticed a timing error on h1asc state word, which I cleared with a DIAG_RESET so it most probably was just a glitch on CPU_MAX.
