[Bug 1631322] Re: ISST:SAN:luckyv1:While Installation, Disk detection is taking more than 4 hours for Host(Ubuntu KVM)

[Michael Hohnbaum]

Canonical has no environment to reproduce this problem.  If IBM were to
profile this and give us some targeted fixes, we could consider them,
but we do not have the resources to commit to investigating this bug.

If this can be reproduced with MAAS, then it might indicate a kernel
issue.  Otherwise, we suspect a performance issue in d-i's disk
detection/handling code.

  Hi

  Today I tried with disabling the SAN disks and tried Installation.It
  went fine and took less an half an hour for installation.

  But that is not the recommended process.

  With disks its not suppose to take more than an hour.

  
  Please have a check on this
