Hello,
I've read over every archived posting I can find about this problem and havne't found a solution that seems to work for me.
Here is the deal: I had a server crash. Hard. I re-built the server (i686, Debian install, kernel 2.4.18). I restored the data for 1 database from tapes to use for testing purposes.
The database has 76 tables, all of type ISAM.
To restore the data, I did the following: 1) /etc/init.d/mysql stop 2) cp all files from tape restore (ISM, ISD and frm for each of the 76 tables) to /var/lib/mysql/databasename/ 3) chown/chgrp/chmod the new files so they're mysql.root, 0664 4) chown/chgrp/chmod the new directory so it's mysql.root, 0775 5) /etc/init.d/mysql start
The server starts just fine. ~> mysql databasename
I get 66 tables working fine, 9 tables reporting "Didn't find any fields in table 'admin_privs'" (or whatever the table name is..that's just 1 exaple).
Here is what I have tried already: 1) backing down to Mysql 3.23 2) Running 2.6 kernel (read that ISAMs aren't binary compatible across OS/platform) 3) CHECK TABLE admin_privs (says: "Incorrect information in file: './path/admin_privs.frm') 4) isamchk (says: "isamchk: error: 'admin_privs' is not a ISAM-table")
Does anyone have ANY ideas?! I'm at a complete loss here (and, of course, getting bashed for not being able to restore from tape).
Thanks, Brian
Brian, Are the tables ISAM or MYISAM ? From the manual - "MyISAM is the default storage engine as of MySQL 3.23"
If they are MYISAM, then you should be running myisamchk. We run this everytime we start/restart our db which checks for tables not closed properly and will automatically repair them. Of course, read the manual for all the myisamchk options.

Walt,
The tables are ISAM type. These are some seriously old tables (originally from version 3.21) and were never updated to type MyISAM. Despite frequent updates to mysqld.
There is a program isamchk which is similar to myisamchk, but it returns the error "___ is not a ISAM-table."
I have read and re-read the man pages for this utility and cannot get it to spit out anything more than the error listed above.
Anyone else got an idea? This is killing me. Brian
The "Didn't find any fields in table 'BLA'" sounds like you're missing the table definition file. If the table name is BLA, the file would be BLA.ISM. MySQL is finding table data, but no table structure.
