Re: [Using Sakai] [sakai-dev] Running out of table space

Hi Ismail,


We experienced similar issue last year (DBWrite error and students were unable to login).


We fixed it as follows:


1.       Run mysqldump:

mysqldump -u root -p sakai > /opt/dbbackup/sakaibackup.sql (target location)

This will list all the tables that are corrupt.


2.       Run myisamchk as follows (for each corrupt table):

myisamchk -r  tbl_name




myisamchk -r  -q tbl_name


Hope this helps.


Thank you.

If you are not concerned about retaining old session information, then you can run:




But this is an unusual error, so you may have some other issue like running out of disk space on the mysql server. See
