Hello,
In CentOS 7 default filesystem in anaconda was xfs, but in ovirt node ng
4.3.9 (based on CentOS 7) the default layout was set to ext4.
In CentOS 8 again the default is xfs and I see that ovirt node ng 4.4 beta4
(based on CentOS 8.1) has now xfs for all filesystems, excluded /boot that
is set to ext4.
In general I have a preference for ext4.
I notice that while in 4.3.9 I could somehow customize partition layout,
even if not recommended, in 4.4 I always get error if I don't accept
automatic partitioning.
What I sometimes do:
- select disk and custom layout
- click done and the storage page appears
- I click the button to create automatically and I get the automatic
partitioning layout
- and here I can change fs type and update settings button and/or change
size of some filesystems (eg for /var/log if using Gluster)
Even if I only set all filesystems automatically generated by installer to
ext4, without changing any size, in the final stage of installation I get
this error and installation aborts:
"
There was an error running the kickstart script at line 5. This is a fatal
error and installation will be aborted. The details of this error are:

If I change nothing and choose automatic partitioning the installation
completes.
Tried different times with same results.
Is it expected? In this case instead of specifying "recommended" it should
be written sort of "mandatory"...
