====== Scheduled Maintenance ====== | ====== Scheduled Maintenance ====== | ||
- | This page is being updated. | ||
- | |||
- | ===== Upgrade of machines 2017 ===== | ||
- | |||
- | Machines to upgrade: **30** | ||
- | |||
- | ==== Reasons: ==== | ||
- | * Main reason is to avoid security holes and update libraries. | ||
- | * Libraries not present in the distribution will be provided with a new mechanism implemented with success by Lunarc. It will be in a test state during 2017. | ||
- | * OpenSuse 13.1 is out of support since November 2016; the software is already old. | ||
- | |||
- | ==== Target distribution ==== | ||
- | |||
- | * Ubuntu 16.04 will be supported until 2021 and is my preference. There will be no more machine update until that time. | ||
- | * OpenSuSE Leap can be installed upon request. Its release cycle and support is unclear, therefore I am not supporting it anymore. | ||
- | |||
- | ==== Tentative Schedule ==== | ||
- | |||
- | ==== Status of other machines ==== | ||
- | |||
- | Papaya will be updated to a more powerful machine running centos7. It will run all services on a raid 1 sw disk set. | ||
- | * nis master | ||
- | * cups print server | ||
- | * mathematica license | ||
- | * intel license (if matfys buys a new one) | ||
- | |||
- | |||
- | ===== Upgrade of vespa 2017 ===== | ||
- | |||
- | Decision pending: centos6 or centos7 | ||
- | |||
- | From https://wiki.centos.org/About/Product : | ||
- | |||
- | ^ ^ CentOS6 ^ CentOS7 ^ | ||
- | ^ Full Updates | Q2 2017 | Q4 2020 | | ||
- | ^ Maintenance Updates | November 30th, 2020 | June 30th, 2024 | | ||

- | Probably CentOS7 for all machines is the best choice. | ||
