[one-users] hooks execution on remote nodes without shared ONE installation dir

[Tino Vazquez]

Hi Nikolay,

The following are the location of the scripts for the FE

  * System wide = /usr/share/one/hooks
  * Self contained = $ONE_LOCATION/share/hooks

The following the location in the CNs

SCRIPTS_REMOTE_DIR=/var/tmp/one

This should be writable by oneadmin and can be changed.

Please let us know if this is not the seen behavior.

Regards,

-Tino
