I use a similar system
So, what are the implications, if any, of installing Leap 15 using its default Btrfs
the main problem in this situation with BTRFS is that it have to get at least x3 or x4 times the ext4 one, simply because some updates are very different from the original system and snapshots uses much room. This may need as much as 100Gb for /. I presently have only 30Gb and was recently hit by the "no more room" error - though t's not the first time and now I can fix it.
this is not a problem per se when 2Tb disks are easy to find, but in our organization, it's not always easy to enlarge the previous ext4 partition
and xfs filesystems
I think the difference is mostly the inode number problem of ext4, but never had to suffer of this one myself
in place of the existing Leap 42.2
installation but leaving the three additional data partitions (and the other installations) formatted in ext4?
no problem there all file systems lives together
Alternatively, should I also convert the three shared data partitions now in ext4 to Btrfs? If so, does that mean that the root filesystem for each of the other installations should also be converted to Btrfs?
better not, just in case BTRFS could show an unexpected problem
just know that some distros do not like BTRFS in openSUSE way so, default ubuntu or debian install may not read or fix BTRFS.
jdd 100 GB is overkill. 50 GB is enough, IME.
