Missing file
Description:
After installation of moosefs package, the file /var/lib/mfs/metadata.mfs.empty is missing. The service moosefs-master.service will fail to start saying:
Apr 25 13:38:37 kvm06 mfsmaster[9341]: [info] loading metadata ...
Apr 25 13:38:37 kvm06 mfsmaster[9341]: [error] can't find metadata.mfs - try using option '-a'This tells us to use the -a parameter.
When the command mfsmaster -c /etc/mfs/mfsmaster.cfg -a is ran it will look for the missing file to create a new, empty /var/lib/mfs/metadata.mfs file.
To manually create the template file:
echo -n 'MFSM NEW' > /var/lib/mfs/metadata.mfs.empty
After this, running mfsmaster -c /etc/mfs/mfsmaster.cfg -a no longer fails and succesfully creates /var/lib/mfs/metadata.mfs.
Use pgrep -f "mfsmaster -c /etc/mfs/mfsmaster.cfg -a and kill the process, then we can start the service moosefs-master.service succesfully.
