Use --redirect to re-use an existing name and run directory

Reported by: marcus Owned by: ros
Component: Rose/Cylc Keywords: cylc-7.8.0
Cc: Platform: NEXCS
UM Version: 10.6



I was trying to restart crashed run u-bc276 from its most recent 01-Dec date prior to the crash (in order to retain proper seasonal means).

I have changed astart to the dump of 01-Dec and updated RUNLEN and BASIS date correspondingly. BUILD_UM remained set to false, as I have had to restart this run previously from another dump.

When submitting with rose suite-run I am getting the following error:

[makoe@exvmsrose:~/roses/u-bc276]$ rose suite-run

I am not sure what is meant by Use --redirect to re-use an existing name and run directory

I did not want to clear the cylc-run directory with rose suite-clean as I was not quite sure if this would prevent me from obtaining a seamless continuation of the run.

Seeing that I am restarting from a 1st December date, such that seasonal means are not affected, could I carry out the above suite clean command or is there another more elegant method that I can use to revive this run?

Many thanks and Happy New Year,

Hi Marcus,

Please comment out the following 2 lines in your ~/.bashrc file and then logout and back in again:

export ROSE_VERSION=next
export CYLC_VERSION=next

Once you've logged back in trying running cylc --version to check that it is now picking up the default version 7.7.2.

A new version of cylc was installed just before Christmas and these commands are saying to use the newest versions of Rose/Cylc which are available for testing rather than using the default versions. The problem with the new cylc version is that it needs a clean cylc-run directory - it does not play nicely with runs which have already begun with a previous version of cylc.

Happy New Year.
