Site reports


Problem with networking --

CMS not pleased with how dCache distributes load on the pools. Tape focused; disk focused setup. Automated

Too many pool-to-pool transfers.

Another possibility would be to use migration module.

Default setup with WASS partition. Probably not worth testing with the network issues.

Besides that --- PoolManager ticket. Tigran promises to look into this.

Have you tried srm-client with the IPv6 fix? No, don't think so, no point with the problem with IPv6 networking.

Once test setup is complete, Xavier can test the new client.

Tigran will try to fix dccp, but this will take more work.

Support tickets for discussion
