How can cells running in a High Availability (HA) setup be manually synchronized? |
To manually sync the two cells please do the following: **This procedure assumes that it is the Primary cell which contains the correct data** 1 - Compare the mcell.dir file in MCELL_HOME\etc on the Primary with the mcell.dir file on the Secondary. If there are any differences, for example Primary has additional remote cells that the Secondary does not, then make the changes on the Secondary. 2 - Copy the cell KB directory (MCELL_HOME\etc\<cellname>\kb) from the Primary to the Secondary. Take care not to copy the mcell.conf file that is in MCELL_HOME\etc\<cellname>. 3 - Stop both the Primary & Secondary cells. 4 - Delete the contents of the MCELL_HOME\var\<cellname>#2 directory on the Secondary cell. 5 - Copy the contents of the Primary cell var directory (MCELL_HOME\var\<cellname>#1) over to the Secondary cell var directory (MCELL_HOME\var\<cellname>#2). 6 - Start the Primary cell and shortly afterwards start the Secondary cell. Then check the status by running the following : mgetinfo -n <cellname>#1 -v activity mgetinfo -n <cellname>#2 -v activity It should show 'Full activity' for the Primary cell and 'Standby activity' for the Secondary cell. |
