Hello
I am considering using logical volumes of an NVMe drive as DB or WAL
devices for OSDs on spinning disks.
The documentation recommends against DB devices smaller than 4% of slow
disk size. Our servers have 16x 10TB HDDs and a single 1.5TB NVMe, so
dividing it equally will result in each OSD getting ~90GB DB NVMe
volume, which is a lot less than 4%. Will this cause problems down the road?
Thanks
Vlad
