Oh. Just noticed it wasn't backported. At least i don't see a backport in the bug. Satoe, anything you need from Mo in order to backport? I asked in the PR if the BZ can be backported as there is no "fine/yes" flag: https://github.com/ManageIQ/manageiq-smartstate/pull/28#issuecomment-342921692 Mo, can you please reply to Satoe? Hey Satoe, Oved, sorry this one go lost somewhere in the gaps. I don't see any reason why this fix could not be backported to previous releases. Go for it. New commit detected on ManageIQ/manageiq-gems-pending/fine: https://github.com/ManageIQ/manageiq-gems-pending/commit/fa86b88c418c00fece26db84ccffc823068cf81c commit fa86b88c418c00fece26db84ccffc823068cf81c Author: Richard Oliveri <oliveri.richard.github> AuthorDate: Fri Sep 22 11:44:43 2017 -0400 Commit: Satoe Imaishi <simaishi> CommitDate: Wed Jan 17 15:49:53 2018 -0500 Merge pull request #28 from movitto/preallocated_lvm2thin_fix Handle case where attempted LVM2 Thin device reads fail (cherry picked from commit 9ae19959eee351a71919996464bca31bea45c336) https://bugzilla.redhat.com/show_bug.cgi?id=1511147 lib/gems/pending/VolumeManager/LVM/lvm2disk.rb | 13 +++++-- .../pending/VolumeManager/LVM/thin/data_map.rb | 14 +++++++ .../pending/VolumeManager/LVM/thin/superblock.rb | 45 +++++++++++++++------- 3 files changed, 55 insertions(+), 17 deletions(-) Satoe, Should this bug be ON_QA please? Thanks. The latest 5.8.z build doesn't have this change. I will move to ON_QA when the next build becomes ready for testing. Verified on CFME-5.8.3.2/RHV-4.1.8: Created a VM with 1 disk with RHEL-7.4 OS, and a 2nd disk, created by the bellow guidance, with RHV storage QE team help. Smart state analysis for this VM ended up successfully. Packages, users, files were collected successfully. Mo's guidance for creating the 2nd image: "create a raw disk image and then partition it and incorporate it into a LVM physical / logical volume structure. https://superuser.com/questions/518554/how-do-you-create-and-partition-a-raw-disk-image https://www.redhat.com/archives/linux-lvm/2008-June/msg00045.html When setting up the volume, make sure it is allocated via 'thin provisioning' https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/thinly_provisioned_volume_creation.html You can then 'dd' a small amount of data onto the logical volume, but you _shouldn't_ format it with any filesystem as that will more certainly allocate more blocks than the original issue can be replicated with."
