Systems
Cobalt
- ✔ Reboots and idrac reboots. (Hopko/Robin)
- ✔ CBM010 will be present before the stopday
CEP3
- ✔ Block access at 08:00 (Teun)
- ✔ Mount DAC cables to headnodes to support floating IP (Hopko/Robin)
- ✔ All nodes: file system check and reboot. (Hopko, Robin)
- ✔ Was broken: Check/debug persistence of Slurm reservations (Reinoud) For the review: We should have a backup in place!
- ✔ NFS mounts for cep3, from all the lof-nodes are using control!
CEP4
- ✔ Connect DAC cable (Hopko)
LEXARS
- ✔ lexar003 reboot using XCAT (148 days up) (Was done by Reinoud 9-4-2018)
LCU
- ✔ Reboot of all Dutch LCU's (teun) (ILT stations in local mode) For the review: We discovered that all LCU's have a fixed NFS mount on /home. This should be an automount.
Central Services
- ✔ Update portals to CentOS/KVM
- ✔ Update and reboot lcs020 .. lcs30
- ✔ Remove sas001 and sas099 (powered off, disconnect cables)
- ✔ Update & reboot NFS server lcs115
- ✔ Almost all nfs mounts on the lcs115 nfs server are over the control network. Only a few correctly use the offline network: only lexar003, lexar004, and lhd002. We should force CEP3 to use off-line!
- ✔ Mainly MAC/SAS, LCU's and Aartfaac machines use NFS over control VLAN. They don't have a off-line of on-line network connection.
- Check resolv.conf settings; see https://support.astron.nl/lofar_issuetracker/issues/10448
