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 2 Zdenek Kabelac 2019-11-12 11:08:55 UTC 
The problem here was that  extension of thin-pool data LV now also wants to resize 'metadata' LV if the growth of data is too big for existing metadata size.

This executed code to change size of 2 volumes at the same time, however second extension expected (wrongly) same segtype is the 1st. LV had and also as a secondary bug tried to use 'percentage' extension for this 'in extent' computed resize.

Both bugs are now fixed with git commit  b9926fb1be3684926ac871b9397839df4c337237.

Comment 3 Zdenek Kabelac 2019-11-12 11:13:48 UTC 
It might be worth to note here - since there are 2 independent extension going on here - it may happen with '%' specifier for some very specific corner cases that lvm2 will not be able to fulfill request as of current internal design limitation -  all the space 'can be taken' by 1st. resize and there might not be enough space for secondary metadata resize - in that case user needs to specify smaller value...
