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.
Environment:
scsi-target-utils-1.0.14-2.el6.x86_64 on RHEL6.1
I updated the /etc/tgt/targets.conf with:
scenario a - 250 targets, each target contains one lun (lvs as backing store)
scenario b - 1 target with 250 luns (lvs as backing store)
Then I tried to restart tgtd or perform "tgt-admin --update ALL", the tgtd restart failed and the "tgt-admin --update ALL" fails every time with the same error message but each time on different target, it seems that each "tgt-admin --update ALL" can deal with only ~7-10 new target which it opens successfully and then it fails.
For the case of 250 targets - I need to run "tgt-admin --update ALL" ~30 times for all devices to be open.
[root@lion ~]# for i in `seq 1 10` ; do tgt-admin --update ALL ; done
