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.

Description Petr Hracek 2015-07-30 11:30:46 UTC 
Description of problem:
Nowadays 'PartitionMounts' content stores /etc/fstab and /proc/partitions to /root/preupgrade directory.
Content should be enhanced so that it will stores partition layout about devices which are needed by kickstart.

Commands which can be used for it are e.g.: pvs, vgdisplay, lsblk, blkid etc.
Comment 2 Petr Hracek 2015-08-05 07:26:46 UTC 
Hi Michal,

would you be able to provide output of commands like:
- lsblk -r
- pvs 
- vgs 
- lvdisplay -C 

All those commands are list/row based outputs.

Could you please also attach anaconda-ks.cfg file?

It would be welcome if machine will be raid, crypted and whatever you want.
Let's say complicated partitioning.

Layout description:

VG created from:
encrypted pv (sda2)
pv(sda3)
encrypted RAID5(md0) created from 3 partitions (sda6,sda7,sd8)

LV:
encrypted lv_data mounted to /data
lv_root mounted to /


swap(sda5)
/boot(sda1)
Comment 6 Petr Hracek 2015-08-07 08:37:11 UTC 
Preupgrade-assistant is not able to create a partitioning layout with LVM and disc drive devices.

https://github.com/phracek/preupgrade-assistant/commit/28dc6a6138f800de0119a7b72e00e5ebc6cb6fd0

When the raid devices will be supported then I will switch this bugzilla to POST.
Comment 7 Michal Kovarik 2015-08-11 12:15:59 UTC 
adding example of raid device:

'/' on raid1 device from 2 partitions
'/home' on encrypted raid0 device from 2 partitions

Can you be specific about what this change does?  Description does not do it for me.

OK.

What are "devices which are needed by kickstart?"  Shouldn't it store all layout info?

Also, what is the format of the data, is that simply output from mentioned commands (in separate files)?  Or is that a YAML/JSON/XML/whatever structure?  And scope of the data?  Do I guess right that it's what one could see from the commands mentioned in comment 2?

We have to enhanced the content so that we are able to reconstruct partition layout for kickstart usage.

Yes, it stores all layout info definitely.

Format data is row-based and separated by ';' for better parsing.
Data are taken by commands lsblk, vgs etc.

I did not update Doc Text yet. I will do it ASAP.
Comment 18 Michal Kovarik 2015-09-09 10:42:45 UTC 
Verified with preupgrade-assistant-contents-0.6.36-1.el6.noarch and preupgrade-assistant-2.1.0-6.el6.x86_64. Required files are created and used by preupgrade-assistant for kickstart creation.
