Planned service maintenance of /storage/brno6/
Dear users,
Let us inform you that on Tuesday, February 23 the Brno's /storage/brno6/ will be unavailable due to battery replacement by the supplier.
Influence on the running jobs:
- the jobs that work with the data saved on (or will save data to) another disk array will not be influenced
- the jobs that perform their computations within the scratch space, which check the success of copying-out the resulting data (e.g., using the script skeleton available at https://wiki.metacentrum.cz/wiki/Running_jobs_in_scheduler#Recommended_procedures), and which will try to save the resulting data into /storage/brno6/ during the outage, will not be influenced as well (you'll find the resulting data in the scratch space of the relevant nodes)
- the jobs that work directly with the data saved in /storage/brno6/ or the jobs that will not check the success of copying-out the data into this array, will most probably crash. If you have some critical/long-term computations, that may be influenced by the outage, let us know -- we'll try to suspend your computation during the outage (however, the success of the suspend process cannot be guaranteed)
Moreover, the user interface (Sunstone) as well as the programming interface (API) for MetaCloud will be unavailable for several hours. Existing virtual machines will not be affected! It will be, however, impossible to create new ones or manage existing ones during the outage.
With apologies for the inconvenience and with thanks for your understanding.
