1566108 – targetcli: Storage Objects gets removed Upon restoreconfig, if the underlying backend is down [rhel-7.5.z]

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.

Description Oneata Mircea Teodor 2018-04-11 14:21:43 UTC

This bug has been copied from bug #1565074 and has been proposed to be backported to 7.5 z-stream (EUS).

Comment 4 Maurizio Lombardi 2018-05-02 10:33:57 UTC

Requires python-rtslib-2.1.fb63-11.el7_5

Comment 5 Sweta Anandpara 2018-05-04 11:03:37 UTC

Validated this on a RHGS cluster having the package targetcli-2.1.fb46-4.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!
