fix
Bleah, what a mess. Neither mkswap nor pvcreate does a great job of zeroing other signatures around the new signature. For some incantations, pvcreate-then-mkswap has an initial 4k on the disk which is *identical* to mkswap-then-pvcreate. :( Sent a patch upstream (and to Jeremy) to check that the swap v1 header has a valid version and page count... "pvcreate" by itself will zero those. (pvcreate -u <blah> will not, unfortunately, so there's still a small hole). But, it fixes Jeremy's case: # blkid -c /dev/null /root/md0-for-esandeen /root/md0-for-esandeen: UUID="kyOPnO-Biwa-PssU-PsXx-kJDW-36Ry-iZvqk5" TYPE="lvm2pv" Patch committed and built and I tested it with my reproducer, so going to close |
