Clarification required about xfs_metadump and xfs_mdrestore

[murali krishna]

Hi All,

Got your email id from Nathan Scott.

Could you please clarify the reasons behind stating below statement in
xfs_metadump man page.



*xfs_metadump should not be used for any purposes other than for
 debugging and reporting filesystem problems*
Man page: http://man7.org/linux/man-pages/man8/xfs_metadump.8.html

I am trying to encrypt my existing xfs drive (/dev/sda2) and would like to
backup metadata using xfs_metadump and restore it back using xfs_mdrestore
after encrypting my drive. In order to retain entire contents of my
realtime partition (/dev/sda1), I need to perform this step.

Can I use xfs_metadump to backup meta-data of xfs  and restore it back
successfully ?
Why xfs_metadump should be specifically used as debugging tool ? Please
clarify ?

Thanks in Advance,
Murali
