Detect all files that have no location in chimera, and invalidate/re-transfer.

We see such files once in a while in dCache monitoring, see example in INC000000541740 .

History

#1 Updated by Natalia Ratnikova over 4 years ago

  • Status changed from New to Resolved

All files have been detected with a query provided by Dmitry, and confirmed by Chih-Hao with another even better query.
Queries are documented in the dcache operations twiki.
All 207 files have been investigated, 202 were the result of Disk/Tape separation, other either normal new files in transient no-location state, or test files without contents (Chih-Hao/Merina take charge for them).
