I'm going to go ahead and close this since it doesn't appear to be a bug
in dmraid. If you can reproduce this starting with clean disks that
have not had any errors, please reopen it.

Yes, the only reason to use it is to dual boot with Windows.
The dmsetup status output lists the state of the disks as RD which

Hi Phillip,
Where do you see that other disk is failing. I can only see part of the
ary pdc_cdgeffcac failing that corresponds to disk sdc.
About DMRAID, Yes, thank you, you are right. I really realized about
this when I saw that BIOS Raid was not able to handle this as needed.

gadLinux, dmraid is handy for people dual-booting with for instance
Windows where it works a bit better, and there is no other common
solution. But for linux-only systems there is no reason to use dmraid.

I'm sorry,

It looks like you have had read errors on one disk, and write errors on

Unfortunately dmraid does not really handle errors, and so is not
recommended for use.
