Red Hat Bugzilla – Bug 159457
Configuration support for Mirroring
Last modified: 2009-04-16 19:11:22 EDT
QA Note: Only 2-way mirroring is supported for this release. To test that the mirror was created properly by the UI, begin with a VG that is composed of partitions on two different hard drives. next, make a SMALL LV on the VG (the bigger the LV, the longer mirror creation takes) Turn the LV into a mirrored LV by editing the LV props and selecting the 2-way mirror radio button. Save some data to the LV and then, i guess you could go in an format one of the mirror partitions, and see if the data is still available...but this starts testing the underlying LVM code, noy the GUI; so I doubt you would want to go much farther with this test path. Hope this helps. BTW, physical extents that are part of a mirrored LV can not be moved.
QA Note: There is also a progress bar showing the progress of mirror synchronization. It should detect synchronization after mirror creation and on the app startup. App should be usable during sync.
Deferring to U3
All set in 1.0.8-1.0
Contrary to the note to QA in the bug, if you only have two physical volumes in a volume group and check "Mirrored," a dialog pops up saying you can't. There must be free space on at least three Physical Volumes to enable mirroring
After creating a mirror, I was able to see the progress of the mirror copy with the `lvs` command, but I didn't see a "progress bar" anywhere in s-c-lvm.
An improper error message pops up when I try to edit properties of a mirror LV that I have created a snapshot of. Steps to reproduce: 1. Create a mirror volume 2. Create a snapshot of the mirror volume 3. Select the mirror volume 4. Click the "Edit Properties" button A dialog with the error message "Logical Volumes with associated snapshots cannot be mirrored yet." After clearing the error dialog, the edit form shows the LV is not mirrored which conflicts with the properties window.
I split my comments out into new bugs that block this one. I'm moving this to FAILS_QA so the new bugs get addressed.
There is a variable in /usr/share/system-config-lvm/lvmui_constants.py (MIRRORING_UI_SUPPORT) that enables/disables UI support for mirroring.
Mirroring enabled in 1.0.17
Removing dep on 180269, as it is defered until LVM support it.
