seaserv2 or seaserv3 directories are missing or unwritable

Posted by on in Hardware

The NASes occasionally have issues with directory permissions changing particularly after a firmware update. If directories "disappear" or are read-only, check the permissions.

seaserv2 is back online

Posted by on in Hardware

Seaserv2 raid1 has rebuilt and no data were lost. The updated sea-going data server is now 3tb instead of 2tb. Both 3tb drives will have to fail for there to be a complete loss of data. Continued syncing with seaserv3 will hopefully prevent any serious loss of work or data.

seaserv2.ucsd.edu crashed

Posted by on in Hardware

One hard drive of seaserv2 crashed today so new hard drives were ordered. Upgrading the raid 1 system to 3tb (2-3tb Western Digital 7200rpm enterprise grade). The 2tb WD Nas Red drive ordered in Mar 2014 crashed already.

Synced all recent files from 1407NH to seaserv3 and the SIO-CalCOFI Technical Group will work there until seaserv2 is back online.

New bottle valves

Posted by on in Hardware
CCTG has decided to build our own bottle valves using General Oceanics (spigots) and Home Depot parts (plugs). Research support price quote was expensive and we can save about 50% using off-the-shelf parts. Once a jig is setup, it will be much easier to make replacement valves.

Windows XP retirement, workstation upgrades

Posted by on in Hardware
Most sea-going data acquisition workstations are still running XP. O2, Salt, Chl, backup Nutrient are running XP. A new i3 microPC was bought to upgrade the O2 auto-titrator along with two USB to Serial A-D (NI USB-6009) adapters. DMW was able to get it operational. Monitor mounting plate is missing but hopefully in a sea-going bin.
