This table was created using the RSE expression:

tier=2&type=SCRATCHDISK

All numbers in TB. Click on table headers to sort.
Used (other) is other RSEs sharing the same space token.
Quota (other) is the sum of quotas defined on other RSEs sharing the same space token.
Used (dark) is the difference between Storage used and Rucio used for all the RSEs on the space token.
Unlocked is data eligible for deletion.

Min space is a limit dynamically set by a collector based on storage capacity of the endpoint (Total(storage) - Used(other)) and according to the following policy:

DATADISK: Min(10% or 300TB free)
SCRATCHDISK: Min(25% or 50TB free)
TAPE: 10TB (arbitrary limit for these tables - actual cleaning depends on the garbage collection algorithm on each site)

Primary diff - amount of primaries (UsedRucio-Unlocked) over a threshold: (Total(storage) - GroupQuota)*0.600000)
Avg tombstone - days between now and timestamp of average tombstone, giving an indication of the turnover of secondary data
