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.

Comment 1 Haim 2010-08-12 09:59:01 UTC 
repro: 

1) work in iscsi storage 
2) create trample from vm running with 2 disks
Comment 3 Igor Lvovsky 2010-08-17 07:56:56 UTC 
Work for me for both COW and RAW disks on my RHEL6.
I need you reproduce it, please.
Comment 5 Haim 2010-08-25 10:40:29 UTC 
ignore latest comment - Paikov managed to reproduce and Saggi provided a patch.
Comment 6 Saggi Mizrahi 2010-08-25 10:56:37 UTC 
It turns out Igor doesn't think it is the same bug. I tend to trust him on that.
Haim, please reproduce on old build so we can be sure it is fixed in new one.
Comment 9 Igor Lvovsky 2010-08-30 11:36:44 UTC 
Be aware to volume format during reproducing.
Comment 10 Haim 2010-09-02 14:59:56 UTC
