Lancaster group ORCA jobs' some features (like TDDFT) require more memory (For example, with PAL8, Memory needs 35304 MB) . To avoid crashing problem, Users need reduce number parallel cores on nodes with less memory. Please see the attached table for the memory size of each node. kml005, kml006, kml009, kml010 have more memories.

Lulu yum updated all crane workstations; Michael updated crane synology DSM.
2/15/17 Lulu: No firmware update on cluster. There are no security updates available via YUM on cluster. Checked all hard drives are fine. Forced fsck on head node 2/12 because of power outrage, no errors found. BIOS update on Crane workstations. yum updated all crane workstations; Michael updated crane synology DSM. Michael updated RESE-01 (serving Crane nfs) to enable auto boot after power off and on.
5/17/17 Lulu: No firmware update on cluster. Forced fsck on head node. kml001 sda is failing. kml001 has been turned to offline. BIOS update on Crane workstations. yum updated Crane nfs server(CRAN-19). yum updated all crane workstations; Michael updated crane synology DSM. Michael patched Hyper-V server where NFS server lives.
8/30/17 Lulu: No firmware update on cluster. Forced fsck on head node. BIOS update on Crane workstations. yum updated Crane nfs server(CRAN-19). yum updated all crane workstations; Michael updated crane synology DSM.

2/21/18 Lulu: No firmware update on cluster. Forced fsck on head node. BIOS update on Crane workstations. yum updated Crane nfs server(CRAN-19). yum updated all crane workstations; Michael updated crane synology DSM (Synology took really long time to boot, it maybe relate with one drive having sectors error). Michael updates Hyper-V server Windows.
6/5/18 Lulu: No firmware update on cluster & Workstations. Forced fsck on head node. yum updated Crane nfs server(CRAN-19). yum updated all crane workstations; Michael updated crane synology DSM Michael updates Hyper-V server Windows.
8/15/18 from Michael: Crane workstations need BIOS update from 1.8.1 to 1.9.2. NFS server aka AS-CHM-CRAN-19 move to a new hosting VM server. Cluster nodes kml001 thru kml008 and the headnode need BIOS update to v1401 from v1201

6/19/2019 Lulu: No security updates available via YUM on cluster. yum updated Crane nfs server(CRAN-19). yum updated all crane workstations; Clean out some crashing log message from Lancaster headnode. (system crashes on 3/2/2019) ; I didn't update Synology and didn't do windows update on server and I didn't do firmware update on Linux workstations. We need do them and forcefsck headnode for next maintenance. kml005 /dev/sdc has some file system issue, I fixed them and it is working now.
