Planned system actualisation on archieval storage in Brno /storage/brno4-cerit-hsm/

2.3.-3.3.2016 - Planned system actualisation on archieval storage in Brno /storage/brno4-cerit-hsm/

Dear users,

Let us inform you that from Wednesday March 2 (9 AM) to March 3 (6 PM) the Brno's /storage/brno4-cerit-hsm/ will be unavailable due to a security actualisation of the system.

*****************************************
IMPORTANT:
The HSM hosts data from Jihlava /storage/jihlava1-cerit/
*****************************************

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/jihlava1-cerit/, 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/jihlava1-cerit/, 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)
