Re: [Moosefs-users] Auto MetaRestore

Hm...
So as far as I understand something may go wrong during restore
and/or something needs my attension.

Could you describe more exactly what scenarios may I face to ?

Hi!

Of course you may do it but we recommend recovering the master server
manually - it is wise to observe the mfsmetarestore process. The automatic
recovery process is quite complicated and until some better scripts are
prepared, you'd rather recover it manually.


Kind regards
Michal

Hi All!

I wonder if it is a good idea to put in init/rc script
which starts mfsmaster something like

mfs_data_path=`grep DATA_PATH /etc/mfsmaster.cfg | grep -v ^# | awk '{print
$NF}'`
if [ ! -f $mfs_data_path/metadata.mfs ]
then
    mfsmetarestore -a -d $mfs_data_path
fi

???????
In my opinion it is bare necessity to automatically make MooseFS healthy
in case of power failure/restore.
