In a HA setup how is the external mount storage is managed ?

  • 1.  In a HA setup how is the external mount storage is managed ?

    Posted Tue April 16, 2019 08:12 AM
    ​We have event processors in HA mode. We have mounted an external storage onto the primary server by adding the entry under /etc/fstab.  The storage is accessible from primary.

    But when a fail over happened and the secondary server is active, the storage partition is not visible under secondary server. Any idea what could be the possible reason ? Do we need to add the entries under /etc/fstab on secondary server well ? How does QRadar manage this external mount storage in its HA setup. Please suggest.

    ​The issue here we are seeing is that after adding the /etc/fstab entry in secondary appliance. Now the server doesnot respond to df -h. Can perform cd to directories by unable to list (ls) anything from /store directory.

    Hi David,

    can you please provide, which kind of Storage you added (FC, iSCSI, ...) ?
    Also it would be good if you can provide the entry of the /etc/fstab on both HA nodes. I do guess that the storage is not allowed to be mounted rw on both sides at the same time.
