Doc Text: |
Previously, the targetcli utility removed storage objects under certain conditions. This happened when the volume hosting the storage objects was down and the user restored target configuration with the command "targetcli restoreconfig". With this update, configuration is now saved at a block granularity, and, as a result, the described problem no longer occurs.

Validated this on a RHGS cluster having the package python-rtslib-2.1.fb63-11.el7.noarch. Had 2 blocks, and validated the contents of both the blocks in the saved configuration. Removed the file /etc/target/saveconfig.json, and selectively tried to rebuild the configuration of one of the blocks, and that succeeded. /etc/target/saveconfig.json had the contents of only the one block that we tried to save. This is good to validate the patch that has gone in in this bug. Please feel free to move this bug to verified after a round of regression. Thanks!
