'LDF' is not a valid database file header. The PageAudit property is incorrect
Ok , is it possible to import without log file?


Yes, but stop using deprecated procedures like sp_attach_db (see the big warning at the top).

Next, you need to supply paths to SQL Server that make sense. Can you get to /home/ in Windows Explorer? Can you do that when logged in as the SQL Server service account?

CREATE DATABASE LIQ_DEV_V9
  ON 
  (
    name = LIQ_DEV_V9, 
    filename = 'C:\...\LIQ_DEV_V9.mdf'
  )
  FOR ATTACH_REBUILD_LOG;


This might fail if SQL Server attempts to create a new log file in a location where that file already exists; so if the damaged LDF file is in that same folder, you may want to rename it, move it, or delete it.

More importantly, you really shouldn't be relying on mdf/ldf files as backups; please read this post:
