I completely agree with Maik, forget about R80.10, make sure to start with a clean install server of R80.20 or R80.30 as there is a new improved filesystem in these versions.
When you decide to go for R80.30, which is the current recommended version, do NOT install any Jumbo before you have finished the migration.
We have a R80.30 MDS running already for a while, which we had on R80.10 before, we only had issue then with domains that wer migrated from R77.30 to R80.10 before the migration to R80.30.
We did a attempt to migrate 102 domains in a R77.30 setup to R80.30 but ran into the jumbo issue, by that time it was to late to start over.
30 domains take about 8 hours to migrate.
