Hi,

I we have problem with harddisk of the server,Suddenly the machine is down, So as there is no any other way to backup of the database i copied all the data which is in /varlib/mysql and send that to another machine and then changed the file and folder permissions and ownerships which the original one have, after that i restarted the server.Here comes the problem with this, mysql could not start again and errors in the error log is

120803 12:02:10 [ERROR] /usr/sbin/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
120803 12:02:10 [ERROR] Fatal error: Can't open and lock privilege tables: Can't find file: './mysql/host.frm' (errno: 13)

I could understand what to do.

THe complete error log is

InnoDB: The log sequence number in ibdata files does not match
InnoDB: the log sequence number in the ib_logfiles!
120803 16:00:10 InnoDB: Database was not shut down normally!
InnoDB: Starting crash recovery.
InnoDB: Reading tablespace information from the .ibd files...
InnoDB: Restoring possible half-written data pages from the doublewrite
InnoDB: buffer...
120803 16:00:11 InnoDB: Started; log sequence number 0 47587
120803 16:00:11 [ERROR] /usr/sbin/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
120803 16:00:11 [ERROR] Fatal error: Can't open and lock privilege tables: Can't find file: './mysql/host.frm' (errno: 13)

What to do any idea please.
