Yes, the preexisting VG does appear if I give the passphrase to unlock sda5. After some more investigation, I noticed that the encrypted PV on sda5 actually has 1 free extent: --- Physical volume --- PV Name /dev/dm-0 VG Name l.sys PV Size 27.68 GB / not usable 24.67 MB Allocatable yes PE Size (KByte) 32768 Total PE 885 Free PE 1 Allocated PE 884 PV UUID UwcvVJ-LeYA-xYg5-KFq9-W6F5-cEtQ-PPX5zi So I guess technically this isn't a bug then, as long as it only uses the free extents and doesn't overwrite the allocated extents. You could create a new VG and use the 1 free extent on that PV along with more extents on another PV. I'm going allocate that last extent manually and try Anaconda again to see what happens. If the behavior changes, then I think it is behaving correctly. If it still offers to use sda5, then there is a bug. On the other hand, I believe Anaconda originally created this PV/VG and the LVs on it--it was the one to leave that last extent free in the first place. That's a different bug though. _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
