Navraceni dat zpet z Jihlavy - kratkodoby vypadek uloziste brno3-cerit

29.-30.10.2014 - Returning data back to Jihlava -- short outage of brno3-cerit disk array

Since we managed to repair the array /storage/brno3-cerit, the data (temporarily hosted in Jihlava) will be returned back to Brno

*** on Wednesday, 29th of October ***

Since it is not possible to perform this transfer transparently, it is necessary to operate the /storage/brno3 array in a not fully consistent state for about 1-2 days.

To minimize the impacts of this transfer on you and your computations, it will be managed as follows:

• current brno3-cerit data (hosted in Jihlava) will be available in /auto/jihlava1-cerit/brno3/export/home/$LOGIN from Wednesday morning
• the data from Jihlava will be (already from Wednesday morning) also available in /storage/brno3-cerit/home/$LOGIN (however, this data may be a few days old -- the synchronisation will be performed on Monday evening).
  Note: In the case of zewura and zegox clusters as well as zuphux frontend, this data are also located in /home/$LOGIN...
• during Wednesday/Thursday, the rest of data from Jihlava (/auto/jihlava1-cerit/brno3/export/home/$LOGIN) will become available on Brno array (/storage/brno3-cerit/home/$LOGIN) -- then, the transfer will become completed.

Note: If you change particular data during Wednesday/Thursday in /storage/brno3/home/$LOGIN, the data can be overwritten by data synchronised/copied from Jihlava.

The running jobs should not be influenced by this transfer.

We are sorry for inconvenience.

With best regards and thanks for understanding,
Tomas Rebok,
