[Bug 990913] Re: RAID goes into degrade mode on every boot 12.04 LTS server

[Joseph Salisbury]

Do you know if this issue happened in a previous version of Ubuntu, or
is this a new issue?

Would it be possible for you to test the latest upstream kernel?  Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.4kernel[1] (Not a kernel in the daily directory).  Once you've tested
the upstream kernel, please remove the 'needs-upstream-testing' tag(Only
that one tag, please leave the other tags). This can be done by clicking
on the yellow pencil icon next to the tag located at the bottom of the
bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.  
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  RAID goes into degrade mode on every boot 12.04 LTS server

Status in “linux” package in Ubuntu:
  New

Bug description:
  I have 2 new Dell PowerEdge R515.
  Box have 2 internal SAS drives and 12 hot swap
  I create a 12 driver raid 6 array on the 12 hot swap drives
  without problem but on every reboot I get a message about 
  either degraded or not enough drives for the raid 6.

  If I shutdown and pull all 12 drives and let boot. Then plug them in.
  The array comes up fine most everytime.

  This happens on both of these new R512

  Also loaded 12.04 LTS server on a R710 and
  the mpt2sas load and times out. I had to
  add rootdelay=180 to boot parms.

  Description:    Ubuntu 12.04 LTS
  Release:        12.04
