On Thursday, October 6th, at 5pm, we will be taking the system down in order to point all systems to new server locations for
- /home
- /opt
- /home/shares
This change will involve
- Migrating those paths from their current NFS mounts to new GlusterFS mount points
- Moving /home/shares to /shares
- Moving /opt/apps to /apps
- Corresponding changes to module files so that, hopefully, most users don’t even notice the changes
The reasons for these changes are as follows
- A GlusterFS configuration for /home, /apps, and /shares will be significantly less complex and more scalable than the current NFS/DRBD configuration, resulting in fewer outages, easier supportability for our staff, and enhanced performance
- Providing a seamless, single view of the filesystems for our Tampa resources and our soon-to-be-released Winter Haven resources required us to use a different approach to making files available and necessitates this change now so that we are ready for the new system deployment in October.
- The mount-point location changes (/home/shares -> /shares, /opt/apps -> /apps) are also to simplify configuration and to be more in-line with how other centers configure their systems
The work will take 2 hours to complete, meaning that the system should be released for service around 7pm that same evening.
Please let us know if there are any questions and concerns regarding this change.
