Yes, I do not do raid5. That does not mean I have not used mdadm. I do raid1+0 (not raid10) and I do not see how that disqualifies me from pointing out that you have the wrong flags for the intended result.
I also do raidz and will probably grow those arrays when support for that is added to OpenSolaris.
Likewise, I have used 3ware and know the difference between using 3ware 750x/850x for raid5 and using 3ware boards that come with bbu caches.
I have done software raid and hardware raid for clusters of servers for a sizable messaging service provider now owned by IBM.
I do not know what makes you think that you can be so full of yourself to the point of thinking that you do not ever make mistakes.

Oh no doubt. Does that mean you do not make mistakes?
BTW, the question was: Can you convert a RAID0 to a RAID5? and the answer is YES from both Neil Brown and Karanbir's post. The only part where I was wrong was I thought it was already implemented. If you want to call that 'giving advice' then hey, feel free.

erm, that would be quite interesting, since you cant split the raid-0 without first moving data into some state of sanity first. Can you point out where Neil says its something that mdraid can do at the moment ?
Ah sorry, did not read his blog carefully enough.

He had a line about RAID0 to RAID5 when I skimmed over it. Looking again...it is not implemented yet. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
