Thank you for your patience while we completed our Lustre upgrade. The Lustre and Spear systems are now online and available for use.
We are now running a new, vendor-supported version of Lustre. There was no direct upgrade path to this version, so we had to backup all of the data to a temporary storage system, perform the upgrade, and then do a full restore the new system. The final data transfer of 155 terabytes took approximately three weeks.
The operating system and software on the Spear servers is now at the same version levels as the HPC, which should eliminate cross-cluster issues when compiling and running jobs or scripts.
Please note that we are now enforcing quotas on the Lustre system. This means that if you were over your quota before the upgrade, you may need to free up some space before you are able to write files again.
You can use the `lfs quota` command to check your group's quota while logged into Spear. For example:
# Show quota usage for your account lfs quota -h -g `whoami` /lustre # Show quota usage for a group lfs quota -h -g [YOUR-GROUP-NAME] /lustre
The quota command will show you your current usage, your soft and hard quotes. If you are over your quota, you will see a "*" after your current usage. For example,
Filesystem used quota limit grace files quota limit grace /lustre 17.21G 90G 100G - 30558 0 0 -
shows that this user is using 17.21 GB with a hard quota of 100GB.
/lustre 105.1G* 90G 100G - 21805 0 0 -
shows that this user is using 105.1 GB and slightly over his quota.
