Doc Text: |
Previously the `/` filesystem automatically grew to fit the whole disk, and the user could not increase the size of `/var` or `/var/log`. This happened because, if a customer specified a disk larger than 49 GB while installing the Hosted Engine, the whole logical volume was allocated to the root (`/`) filesystem. In contrast, for the RHVM machine, the critical filesystems are `/var` and `/var/log`.
The current release fixes this issue. Now, the RHV Manager appliance is based on the logical volume manager (LVM). At setup time, its PV and VG are automatically extended, but the logical volumes (LVs) are not. As a result, after installation is complete, you can extend all of the LVs in the Manager VM using the free space in the VG.
