General Error 126 Incorrect Key File For Table
I'm trying to run a rather large query that is supposed to run nightly to populate a table. I'm getting an error saying Incorrect key file for table '/var/tmp/#sql_201e_0.MYI'; try to repair it but the storage engine I'm using (whatever the default is, I guess?) doesn't support repairing tables. how do I fix this so I can run the query? mysql mysql-error-126 share|improve this question edited May 5 '11 at 23:24 OMG Ponies 198k36356415 asked general error 126 incorrect key file for table try to repair it Mar 11 '10 at 21:15 Wayne Molina 7,7441770134 the tmp folder has a limit usually 2GB, try df -h to see it –Elzo Valugi Jan 18 '12 at 12:17 add a comment| 6 Answers 6 active oldest votes up vote 1 down vote accepted The storage engine (MyISAM) DOES support repair table. You should be able to repair it. If the repair fails then it's a sign that the table is very corrupted, you have no choice but to restore it from backups. If you have other systems (e.g. non-production with same software versions and schema) with an identical table then you might be able to fix it with some hackery (copying the frm an MYI files, followed by a repair). In essence, the trick is to avoid getting broken tables in the first place. This means always shutting your db down cleanly, never having it crash and never having hardware or power problems. In practice this isn't very likely, so if durability matters you may want to consider a more crash-safe storage engine. share|improve this answer answered Mar 12 '10 at 7:41 MarkR 46.1k886118 add a comment| Did you find this question interesting?

In fact, this database is running on an Amazon RDS instance, which means that it is basically a managed server dedicated to MySQL with a very standard configuration. Also, the disk allocated to us is only about 25% full. Considering that perhaps there disk on the VM (powered by Xen I believe) is full, and not my allocated disk space which is likely not even in the same room (network storage), I rebooted the RDS instance in the hope that I would get a new instance on another VM. However, that did not help. What should be my next troubleshooting step?
