      Not familiar with what might make HyperV do that 😞

      Tried to make a new VM and just attach the VHDX with no luck.

      Created a complete VM installed CentOS and then shut down and added the old drive as a second HDD. it shows up when I check fdisk. So now to figure out how to copy the everything.

        looks like sdb3 is not readable? sdb1 and sdb2 mounted and were readable.

        Here is a screenshot. typo's included 🙂

            If you can see it like that, what is stopping you from just copying it?

                  Oh database files, that sucks. What DB engine is it? MyISAM? InnoDB? Something else?

                    Wordpress database. running on centos7. so it is mariadb

                      MariaDB is an RDBMS. It isn't a DB engine. It uses other engines. MyISAM and InnoDB are the two most common. There is no MariaDB database engine option.

                          daerma.com is giving me some weird permission error too .i cannot install a plugin or theme, because it pops the FTP login info like my old install did. but I chown'd the wp directory to apache:apache. not sure what is up.

                            well i have been unable to recover everything correctly by copying from the drive that was originally attached.

                            Would it be possible to copy the boot partitions to the old drive and then try and attach it as the primary drive? That is more in depth CentOS than I know how to handle.

                              At this point I think i will just nuke and rebuild from scratch if I cannot copy the boot partition and have the system come back up. Going to be out all afternoon with the family so looking forward to any ideas you all come up with.

                                With WP issues, I often just untar a fresh install over top of the old one to make sure that there is no cruft.

                                  Possible but unlikely. That could be a lot of work to get working right.

                                      Was easier really. Well would have been easier if the Wordpress export file had imported correctly..

                                          I posted in this thread.
                                          http://wordpress.org/support/topic/import-process-only-displays-page-header

                                          Here is my screenshot. Notice how the source code on the import page just stops dead mid page. there is obviously some kind of error in the plugin.
