Hello all,
MySQL doesn't start. Here the logs:

InnoDB: you should now edit innodb_data_file_path in my.cnf back
InnoDB: to what it was, and remove the new ibdata files InnoDB created
InnoDB: in this failed attempt. InnoDB only wrote those files full of
InnoDB: zeros, but did not yet use them in any way. But be careful: do not
InnoDB: remove old data files which contain your precious data!

We've found any information about this issue. The warning above suggests to delete the new ibdata files, but our files have a huge size (4Go) and we would like not to delete our precious data...

Maybe a clue, remaining space disk on MySQL data partition becomes short:
Filesystem Size Used Avail Use% Mounted on
/dev/sdc2 42G 34G 5.9G 86% /data
We are aware of this lack of space, and we'll solve it sooner as possible; can it be directly the cause of the innodb issue?
Thanks for your help!
