Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Fixed In Version:	6.1.0.171	Doc Type:	Bug Fix
Doc Text:	Sometimes a Universal Deduplication Service (UDS) index for a Virtual Data Optimizer (VDO) volume falls offline due to a read error on the underlying media. In this case, running the "vdo status" command to check the status of the affected VDO volume previously displayed "Index status: online" even though the index was offlined due to the read error. This update fixes the VDO source code that handles the index status. As a result, the status now correctly reads "Index status: offline" in the described scenario.	Story Points:	---

This bug has been copied from bug #1565311 and has been proposed to be backported to 7.5 z-stream (EUS).

Comment 3 Jakub Krysl 2018-06-14 08:46:02 UTC

I could not get the index to failed state as vdo managed to rebuild the index each time. Regression testing passed.
