Re: [Moosefs-users] HELP!!! 250T Data lost!

Hi!

 

Please tell what MooseFS version do you use? What OS is on master/chunks? Did you have metalogger running?

 

Try to find metadata in these locations:

/metadata.mfs.emergency

/tmp/metadata.mfs.emergency

/var/metadata.mfs.emergency

/usr/metadata.mfs.emergency

/usr/share/metadata.mfs.emergency

/usr/local/metadata.mfs.emergency

/usr/local/var/metadata.mfs.emergency

/usr/local/share/metadata.mfs.emergency

 

Kind regards

 <mailto:moo...@li...> i`m crazy, my boss will kill me ..

 

on mfsmaster machine, i execute "mfsmaster restart", then it crashed.

 

err info is here：

======

working directory: /var/lib/mfs

lockfile created and locked

initializing mfsmaster modules ...

loading sessions ... ok

sessions file has been loaded

exports file has been loaded

loading metadata ...

loading objects (files,directories,etc.) ... loading node: read error: ENOENT (No such file or directory)

error

init: file system manager failed !!!

error occured during initialization - exiting

=======

 

no "metadata.mfs_back" left for me . i think it because there is no space left on mfsmaster hard disk.

 

 

 

then i log in mfsmetalogger server. i execute "mfsmetarestore -a -d /var/lib/mfs", and i also report err! 

err info is here:

======

file 'metadata.mfs.back' not found - will try 'metadata_ml.mfs.back' instead

loading objects (files,directories,etc.) ... loading node: read error: ENOENT (No such file or directory)

error

can't read metadata from file: .//metadata_ml.mfs.back

=======

 

 

what can i do now?

 

 

PLEASE SAVE MY LIFE.....
