Re: [Moosefs-users] problem metadata

[Sébastien M. <seb...@u-...>]

Thank you Michal for your help.

I try this command but it doesn't work. The command termined by "killed 
: 9".

But, why to use only chanlog.1.mfs and changlog.1.mfs ?

I have try the command with success on the advice of Davies ;):

# mv metadata.mfs.back.tmp metadata.mfs.back
# mfsmetarestore -a -d /[directory metadata]
