Created attachment 996925 [details] anaconda error when rescue booting with RHS 3.0.3 iso Description of problem: Rescue boot fails since dm-thinpool.ko is not included in initrd.img of RHS iso Version-Release number of selected component (if applicable): RHS 3.0.3 (latest iso) How reproducible: After install RHS and configure gluster volumes with dm-thinpool, boot rescue mode with RHS 3.0.3 iso media. Steps to Reproduce: 1. Install RHS and configure gluster volume with dm thinpool. 2. Shut down 3. Boot rescue mode from RHS 3.0.3 cdrom Actual results: rescue boot fails due to error of "/usr/lib/anaconda/storage/devicelibs/lvm.py"(see attached error) Expected results: rescue boot successfully. Additional info: RHS3 uses dm-thinpool based LVs for handle snapshots. I think the initrd.img in iso should contain dm-thinpool.ko. I confirmed that dm-thinpool.ko isn't included in following isos. RHEL6.x dvd iso RHS3.0.3 iso And it's included in iso of RHEL7. Could you consider update iso of RHS?
