As you wrote, in a raid environment, the controller will detect a failed
disk and redirect I/O to the working drive.
With no RAID, is gluster smart enough to detect a disk failure and redirect
all I/O to the other server?
A disk can have a damed cluster, so only a portion of itself will became
A raid controller is able to detect this, gluster will do the same or still
try to reply
with brokend data?
So, do you suggest to use a RAID10 on each server?
- disk1+disk2 raid1
- disk3+disk4 raid1
raid0 over these raid1 and then replicate it with gluster?
