FCM_MAIN: Extract failed

Reported by: sara123fenech Owned by: ros

UM Version: 7.3


To whom it may concern

I am currently running a copy of job (xjnjn) having jobid xktov. It was working on Monday however since yesterday it's no longer working. Upon submitting I'm getting the below message:

FCM_MAIN: Calling Extract ...
Base extract: failed
See extract output file /home/sara123fenech/um/um_extracts/xktov/umbase/ext.out
FCM_MAIN: Extract failed
Tidying up directories ...
FCM_MAIN stopped with return code 255

umui_runs/xktov-056094006/SUBMIT[13]: .[61]: .[369]: .: line 72: PROMPT_COMMAND: is read only

Your job directory on host is:
Your compilation output will be sent to file:
Your model output will be sent to file:

I have checked out the ext.out file and I found the message below:

[FAIL] ssh -n -oBatchMode=yes mkdir -p /home/n02/n02/sfen/um/xktov/umbase/cfg failed (255) at /home/fcm/fcm-2014.12.0/bin/../lib/FCM1/ line 755.

I have tried to submit it a number of times (each time deleting previous files) however it still doesn't work. To my knowledge I haven't changed anything. The only change I've noticed, is that upon logging on Puma I get the following message:

/home/sara123fenech/.profile[24]: rt: not found [No such file or directory]

Not sure if this has anything to do with it. I have also check out similar tickets, which seemed to have a password-less problem. I can successfully log on Archer from Puma without a password, so I assume this is not the issue.

Thanks for your help

This is a problem we have all been having - it is network related (we think) . Please try submitting again - maybe a few times.

Hi Grenville,

Thanks for your reply. I have submitted the job a number of times yesterday, and today but it still didn't work. Thanks

Hi Grenville

following my previous comment I have tried to submit another job which we used in the UM course and it worked fine, it is a different UM version though (8.2). Not sure if this suggests that something is wrong with my previous job or if it's something to do with the version.

Hi Grenville

I am having similar problems. I am using the same version as Sara (7.3) and have tried submitting under various different settings over the past two days and keep getting a reply containing, 'extract failed'.

Do you know if this is a network problem or something specific to the version me and Sara are using?

Hi Jamie,

The reason your jobs are failing to extract is because you have run out of disk space in /home on ARCHER. See e.g. ~/um/um_extracts/xldpd/umbase/ext.out. You need to delete some files from $HOME on ARCHER before you try running any more jobs.

Hi Sara,

I'm closing this query now. We are still working to resolve the intermittent ssh failures during submission.
