I have tried to find information about this question in google, but
found nothing.
The question is: are there issues using different disk i/o schedulers
(by appending elevator=xxx to the kernel boot command line) when using
md RAID1 or RAID5?
I seem to remember that someone told me that using elevator=deadline can
cause perfectly good disks to be kicked from the RAID because of some
latency issues that make the disk seem unresponsive (and dead) to the
raid software.
Is this true? Are there compatibility issues using different i/o
schedulers with software raid?
Thanks
I've been running several vmware server hosts with elevator=deadline on
raid1 for a year or so now, with no problems.
