Hello Christian.
Our current setup has 4 osd's per node.When a drive fails the
cluster is almost unusable for data entry. I want to change pour set up

Hello.
In this set up:
PowerEdge R720
Raid: Perc H710 eight-port, 6Gb/s
OSD drives: qty 4: Seagate Constellation ES.3 ST2000NM0023 2TB 7200 RPM
128MB Cache SAS 6Gb/s
Would it make sense to uses these good sas drives in raid-1 for journal?

I've 2 dell systems with PERC H710 raid cards. Those are very good end
cards , but do not support jbod .
They support raid 0, 1, 5, 6, 10, 50, 60 .
lspci shows them as: LSI Logic / Symbios Logic MegaRAID SAS 2208
[Thunderbolt] (rev 05)
The firmware Dell uses on the card does not support jbod.
