If I were you I would get rid off that partion schema and would change it to GUID partioning ! I don't know if it's able to do without new installation !
I have only nominal familiarity with partitioning tools other than that which I've been using cross-platform for two decades exclusively, DFSee[1], which is not FOSS. Because DFSee can make this conversion, I have to think others can do it as well.
In my view/with my understanding: if you ever get in the position/the need to do an new install with new partioning your /home on an logical partition is in danger. - maybe I'm wrong ?! -
If you move to GUID partioning you circumvent the barrier of 4 primary partions OR 3 prim. plus x logical.
That's 4 primaries: 3 normal primaries, plus a primary called extended. It is the extended which "contains" logicals. The extended is actually a chain of sectors that delineate one logical partition, and optionally point to a next sector in the extended chain.
You simply get more then 4 primary partitions. - don't know the limit -
IIRC, 256.
you need a partition named "Bios Boot" with 1-2 MB size as a first (?) partition.
Technically, much less than 1MB is needed, but not using a multiple of 1MB would normally disrupt conventional partitioning's sector alignment: https://en.wikipedia.org/wiki/BIOS_boot_partition
