Currently in a good shape.

NDGF upgraded to dCache 6.0 last week -- a few pools still to upgrade. No issues so far.

RT 9747

RT 9699

one issue: pin

RT 9752

Samuel will check if the HSM script is still running for the cancelled PNFS-ID stage requests.

RT 9770

Advice on how to decommission xrootd doors smoothly.

PIC

We are planning to upgrade 5.2 next week.

Experience problems with checksum -- FTS transfers failing checksum is different from the one in Rucio.

Transfers are finished OK -- checksum is OK.

Downloading the file

A file size in Rucio is a few bytes out

RT ticket 9773

Problem seems to be Rucio metadata is inconsistent with dCache metadata. Subsequent FTS transfers fail because the stored file doesn't match expected file size and checksum.

Support tickets for discussion
