Resolution

The reason of the issue is that file system/package structure has been changed in FC6/RHEL5ES/CentOS 5 and PPCP versions. This happens as site were backed up with some directories/files that were not created in older versions, but are in new ones on user creation time.

The usual thing is X11 folder, so it is recommended to rename '/home/virtual/FILESYSTEMTEMPLATE/siteinfo/usr/lib/X11' (for example to '/home/virtual/FILESYSTEMTEMPLATE/siteinfo/usr/lib/ZZZ') and then perform the import.

If this was not enough and you are still getting the same error - rename /home/virtual/FILESYSTEMTEMPLATE/siteinfo/usr/tmp folder.


You can find any additional folders by doing 'strace' on the process, the error you will get will be similar to:

unlink("/home/virtual/site56/fst/usr/tmp") = -1 EISDIR (Is a directory)
link("/home/virtual/FILESYSTEMTEMPLATE/.tmp/tmpdir_28719_GfkyNW/usr/tmp", "/home/virtual/site56/fst/usr/tmp") = -1 EEXIST (File exists)

This mean that /usr/tmp has been created on creating user by PPCP, but /usr/tmp exists in imported archive.


After the import, you have to rename the directories/files back.
