fsck errors and a lot of files in /lost+found

[ESGLinux]

Hi All,

today I had to reboot a server that was running with problems and when I
rebooted it gives me the error that there was problems with the disks

After a long process of fsck I finally rebooted the machine but now I have a
directory /lost+found with a lot of files like these:

#1474871  #1999211  #1999240  #1999271  #1999304  #1999418  #1999445
 #2064420  #2064531  #2064570  #2064612  #2064755  #66008   #826053  #827096
 #832422
#1474876  #1999214  #1999241  #1999272  #1999307  #1999419  #1999446
 #2064422  #2064533  #2064571  #2064614  #2064756  #66011   #826230  #827097
 #832500
#1474877  #1999217  #1999242  #1999273

I noticed I have lost files (for example /etc/postfix/main.cf isn´t there so
my postfix does not start)

My question is, How can I check this files to know which files I have lost?

Thanks a lot in advance
