Category: General AnnouncementThis notice affects users with data on the /work filesystem of all HCC resources (Crane, Sandhills and Tusker). Files not accessed for over 6 months will be removed this week. This will now be enforced as an ongoing policy. This was originally announced for all HCC resources September 29, and no more warnings will be sent unless the policy or situation changes. These files will not be recoverable. All of /work remains subject to further file removal if conditions so demand (i.e. the system is overrun).
show details...
These file purges keep the /work filesystem available and performing at a more reliable and higher level. Some initial purge statistics for HCC resources are as follows:
Crane: Total files: 36,306,639 Total amount: 274TB Oldest file removed was last accessed 1033 days ago.
Sandhills: Total files: 14,192,087 Total amount: 62TB Oldest file removed was last accessed 1449 days ago.
Tusker: Total files: 18,221,530 Total amount: 81TB Oldest file removed last last accessed at least 420 days ago.
Long term storage is available for $60/TB/year on Attic (http://hcc.unl.edu/attic).HCC now purges (i.e. removes) files from /work that are over 6 months old. You may run
hcc-purge
to see which files (if any) are old enough to be removed at the next purging at any time. Purges will be performed each week on an ongoing basis moving forward. Scans for files to purge will be done twice a week. Please see
https://hcc-docs.unl.edu/display/HCCDOC/Handling+Data
for further details. - 2016-10-11: HCC Anvil web interface maintenance complete

show details...
Access to the anvil-beta.unl.edu web interface, including creation, deletion, and web console access to VMs, will be unavailable until the maintenance is complete. Running virtual machines will not be affected.
During this maintenance, we will be moving the web service to new hardware. We anticipate the move will be completed by the end of the day. We will send a followup notice when work is complete.We have a scheduled maintenance for the HCC Anvil web interface for Tuesday, October 11 starting at 10am.

Category: General AnnouncementThis notice affects users with data on the /work filesystem of Tusker. Files not accessed for over 6 months will be removed this week.
HCC now purges (i.e. removes) files from /work that are over 6 months old. You may run
hcc-purge
to see which files (if any) are old enough to be removed at the next purging at any time. Purges will be performed each week on an ongoing basis moving forward. Scans for files to purge will be done twice a week. Please see

for further details.
All traces of the originally purged files will be removed this week. The initial purging was simply a move to a quarantine area as a safeguard since this is a newly implemented policy, but the new location also was on /work. The /work file system is over 90% full, and the 18 Million files totaling over 81 TB of space will be removed. All of these files had not been accessed in over 6 months. This should help the overall performance of the system and will avoid an overrun of the /work filesystem. If you need a place to store data longer term, Attic space is now available for $60/TB/year (and is stored redundantly both in Lincoln and Omaha).
Best regards,
David Swanson
