One could still use multi row approach in that case:
Data: RAID 0 System: RAID 1 Unused
/dev/vdb 307.25 MB - 2.23 GB
Data: RAID 1 System: RAID 0
250.12 MB 128 MB
Data: RAID 0 System: RAID 1 Unused
/dev/vdc 307.25 MB 8 MB 2.69 GB
Data: RAID 1 System: RAID 0
250.12 MB -
[…]
But still if if can be arbitrarily long due to that per object replication
config, a vertical output might and leaving graphical representation to a
Qt Quick application or so might be better.
