I am looking to run IRIS for UNIX on the Linux Ubuntu 22.04 platform and need to determine which filesystem configurations are considered supported. The three options under consideration are Ext4, LVM with Ext4, and OpenZFS. Currently, the system is running on a raw Ext4 filesystem, but there is a desire to switch to either LVM with Ext4 or OpenZFS to make it easier to handle disk usage.
This leads to two questions:
Are either of these two configurations considered to be tested and supported by InterSystems?
