Cylc2 error on Jasmin

Rose/Cylc and FCM

Hi there,

I am having a strange issue with Cylc8 on Jasmin. My suite (u-dg275) ran last week absolutely fine. However, now, it is compiling correctly, but failing on submit with the error message below:

I have the same issue with u-dp360 & u-dq927. I wondered if this is a known issue? I honestly wouldn’t know how to start debugging the way cylc installs and runs roses suites.

I have tried wiping all my suites and re-installing etc.

EDIT: this is an intermittent fault. The suites have run successfully and are now faulting again.

EDIT2: this may be a Jasmin hardware issue as I am now receiving the error message “mkdir: cannot create directory ‘/home/users/tightasa/cylc-run/u-dq927/run1/work’: No such device”.

All best & thanks

I’ve been getting this error too and have reported it to the JASMIN Helpdesk.

I think that it’s due to the LOTUS2 node being unable to see the scratch file system. I can explain how this leads to a ‘File exists’ error if you are interested.

Hi David, - okay thanks. I reported once it seemed like a hardware issue as well. Honestly I doubt I would understand!

Hi David - quick update on this. I am now getting a similar error - rather than submitting, suites compile and then hang before timing out. I have submitted relevant Job IDs to the Jasmin helpdesk. Overall I am getting lots of these intermittent faults with the LOTUS2 / cylc2 server at the moment. OP
