Description of problem: ----------------------- When NBDE setup is completed, the target device is created under /dev/mapper/luks_sdx. When attempting for RHHI-V deployment from web console(cockpit), and attaching the LVM cache, logic uses device name as '/dev/luks_sdc' instead of '/dev/mapper/luks_sdc' Version-Release number of selected component (if applicable): ------------------------------------------------------------- cockpit-ovirt-dashboard-0.14.8 How reproducible: ----------------- Always Steps to Reproduce: ------------------- 1. Start the HC deployment from cockpit 2. On the bricks tab provide the device name as '/dev/mapper/luks_sdc' 3. Enable LVM cache and provide SSD as '/dev/sdg' Actual results: --------------- Generated inventory file contains reference to '/dev/luks_sdc' Expected results: ------------------ Generated inventory file should contain '/dev/mapper/luks_sdc'
The generated inventory contains: <snip> gluster_infra_cache_vars: - vgname: gluster_vg_luks_sdc cachedisk: '/dev/luks_sdc,/dev/sdg' cachelvname: cachelv_gluster_thinpool_gluster_vg_luks_sdc cachethinpoolname: gluster_thinpool_gluster_vg_luks_sdc cachelvsize: 220G cachemode: writethrough </snip> Expected is that the device should be */dev/mapper/luks_sdc* <snip> gluster_infra_cache_vars: - vgname: gluster_vg_luks_sdc cachedisk: '/dev/mapper/luks_sdc,/dev/sdg' cachelvname: cachelv_gluster_thinpool_gluster_vg_luks_sdc cachethinpoolname: gluster_thinpool_gluster_vg_luks_sdc cachelvsize: 220G cachemode: writethrough </snip>
This error is also true for multipath configuration enabled, where the device name is '/dev/mapper/WWID' for example: /dev/mapper/3600304801a48610125f9a6571e612c29
Tested with cockpit-ovirt-dashboard-0.14.9.el8rhgs When attaching the LVM cache ( /dev/sdx ) with the LUKS device ( /dev/mapper/luks_sdx ), the deployment happens in the right way.
