The server’s response is:<\/span><\/p>\r\n

you are the 31399th user to install this version<\/span>
You want me to create a v09 style flexible-size internal meta data block.<\/span>
There appears to be a v08 flexible-size internal meta data block<\/span>
already in place on \/dev\/vdd at byte offset 499826814976<\/span><\/p>\r\n

Valid v08 meta-data found, convert to v09?<\/span>
[need to type ‘yes’ to confirm] yes<\/span><\/span><\/p>\r\n

488097196 kB data area apparently used<\/span>
488097196 kB left usable by current configuration<\/span><\/p>\r\n

Even though it looks like this would place the new meta data into<\/span>
unused space, you still need to confirm, as this is only a guess.<\/span><\/p>\r\n

Do you want to proceed?<\/span>
[need to type ‘yes’ to confirm] yes<\/span><\/span><\/p>\r\n
