Volume Group with Multiple Units - Striped or Spanned?
Hello,
A simple technical question:
If I create multiple Units either with software RAID or hardware RAID and then combine them into one Volume Group, is the data spanned or striped across the Units?
Spanned = data fills up Unit 1 before anything goes to Unit 2, Unit 2 fills up before Unit 3, etc
Striped = data is spread equally across all Units
I would not recommend this due to the fact that if 1 of the joined arrays in the Volume Group had an issue it would take down the whole Volume Group until it is fixed creating an outage during production until everything is resolved. When you join them it is spanning. Best would be to have 3 different Volume Groups.
