When upgrading Data Collection Devices, an error "/var partition information not found" may be encountered.


Upgrading the BIG-IQ cluster using the UI will not work.


This occurs when the Data Collection Device has partitions formatted using the ext4 file system. Typically ext4 is not used on BIG-IQ versions prior to 8.0, but if a BIG-IQ has upgraded to 8.0 or later, then downgraded to a pre-8.0 version, the partitions created during the downgrade will be ext4.


Installing an earlier version from a later version is not recommended. If you are in this situation, you may have to remove the Data Collection Devices, upgrade them individually, and then add them again.
