Hi. I have a quick RAID 5 question. Sort of a repost, but I can't get an
answer.
May I assume that LVM does not support RAID 5 due to the serialization
problems? Theoretically, 2.6 will have a fix but this has already been a
problem for over two years. And if 2.6 develops like 2.4 did, then we should
not use it for production for many months after its release.
Thus it looks like people will not be able to deploy these types of Linux file
servers for some time hence -- a terrible thought.
For example, testing with LVM2 and DM from CVS, I made one snapshot under
light network load and it brought my machine to a complete stop, then oopsed
it. I'm glad to help if any developers are interested.
Thanks.
