nonproportional InnoDB storage on disk

[Maxim Veksler]

Hello everyone,

I'm having a problem that might possibly suggest a bug ?


All our tables are InnoDB.
The size of storage on the disk is 27 times bigger then the textual dump of the db, I've tried running flush tables + flush logs and it doesn't help.

Could someone please suggest a solution or should I report an issue ?


Thank you,
Maxim.
