Mysql – thesql crashed and lost table descriptions “show table status” all null

Due to a air-con failure the SAN with our mysql database files crashed.

When it came up there were problems with queries taking many seconds to run, further investigation revealed that the *.frm files were corrupted;

mysql> show table status;

also trying to compare seems to confirm that;

[root@db01 discovery_prod]# mysqlcheck -hlocalhost -r discovery_prod
discovery_prod.STATUS_REPORT
error    : Incorrect information in file: './discovery_prod/STATUS_REPORT.frm' 

repair table SOMETABLE output as follows;

 mysql> repair table STATUS_REPORT;

Is it possible to restore the frm files from the data files? are there any utilities that can work backwards, as the database is up and serving queries? Just really slowly…
