STAR Flow, Chirality and Vorticity PWG

[Ding Chen <dchen087 AT ucr.edu>]

Dear FCV and experts,

I want to complain it is hard to access the full statistics of many datasets and it's not just me.

For Run19 19.6 GeV, analyzers find themselves needing to re-submit more than 8 times to get more than 80% of the statistics.

For Run18 FXT 3 (3.85)  GeV data, analyzers find the statistics are 20% less, need re-submit multiple times to reach 90% of the statistics.

For Run18 FXT 7.2 (26.5) GeV data, I can only get less than 50% percent of full statistics. 

Adding to that, many are bugged with the notorious "3011" error, which will kill the whole job if one file has such an error.

When the 7.2 GeV data was stored at NFS, I had no issue accessing the full statistics. I suspect that it's due to some issues on distributed disk (DD), or the communication with it, but I'm no expert on that. 

Since it impacts many analyses. I'd like to know why this is the problem and more importantly if there's any solution to that? 

Best regards,

Ding
