Moo get not working

Reported by: csteadman Owned by: ros
Component: Archiving Keywords: MASS
Cc: Platform: Monsoon2
UM Version: 8.4



I'm trying to get files from the MASS archive and it's not working today. I've tried multiple files. This file is small and should be retrieved quickly, certainly within a few minutes, however, moo get doesn't retrieve the file. There's no error message, it just hangs.

clstea@xcslc0:~/temp> moo ls -ltr moose:/crum/xnumk/aph.pp/xnumka.ph2003feb.pp
F colin.johnson 0.00 GBP 53445832 2017-11-27 12:27:07 GMT moose:/crum/xnumk/aph.pp/xnumka.ph2003feb.pp

clstea@xcslc0:~/temp> moo get moose:/crum/xnumk/aph.pp/xnumka.ph2003feb.pp .
### get, command-id=481111305, estimated-cost=53445832byte(s), files=1, media=1

I use the UMUI, UM vn 8.4 on monsoon.

Best wishes,

Hi Claudia,

That command works for me. Can you please try again?

Hi Ros,

Thanks for the reply. It seems to be working intermittently, and when it is working, it's slower than usual. It seems that the command I sent to retrieve the jan and feb files worked (but sometimes took 17 minutes a file), but I tried submitting other requests and they don't seem to be retrieving the files at all. I've been waiting for one for 25 minutes.

Here's the ls -ltr for the files I retrieved today. All of a sudden at around 16:27 a bunch of requests I sent earlier started working, then at 17:55 it stopped and I haven't been able to get any to work since. I've tried both postproc and xcs.

Hi Claudia,

I've passed this to the Met Office.

Hi Claudia,

I've just heard back from the Met Office and they are aware of problems with the performance in bringing data back from tape to disk that has arisen in the past month. Unfortunately, a lot of the slowness is due to the sheer volume of activity on the system at the moment. There are plans to upgrade the backend software which will enable handling of queries more effectively but this requires some other work to be done first.
