Hello,
In Windows, I created a RAID-5 array on my Intel Matrix Storage
Manager compatible chipset. Across 5 500GB drives, I made a volume
named VIDEODATA. It finished initializing on Windows and is currently
in a Migrate state that will take a total of 36 to complete (so if
that's the problem I'll just blow up the array and make a new one
which will only take 12 hours to initialize).
The array works fine in Windows but it will not work in Linux (Ubuntu
11.10 x64) under mdadm or dmraid. dmraid just creates a mapper that
claims to have no partitions (an obvious lie), is reported as 2TB when
the array is actually 1.8TB, and is generally useless.
I tried to start the array in mdadm (after uninstalling dmraid and
rebooting) but it thinks the array contains 5 spares. In 'disk
utility', RAID array /dev/md127 is listed as "Not running, partially
assembled".
I'm very confused as to how to continue at this point.
Here is some output someone told me the list would want:
r000t@editsuite-linux:~$ sudo mdadm -Q /dev/md/imsm0
