main CDS file server in read-only mode
At midnight this morning the main control room NFS server suffered a scsi error and the /ligo file system went into read-only mode. This means you cannot modify or create files on the /ligo file system, which includes user home directories and the cds wiki pages. This is a known problem with this type of integrated computer and file server, and the only resource is to power cycle the machine, which cannot be performed remotely.
The immediate problem this causes is the hourly autoburt backups are not recording. I can reroute those to the h1boot file system temporarily until I can get to the site to reboot the server.
The problem occured at 4 mins past midnight, Sat 9 Feb.
cdsfs0 rebooted. File system is now available for writing. All Ubuntu workstations need to be rebooted to reconnect to the server, Mac OSX machines remount the file systems. I have restarted all the workstations in the control room.
