SQLSTATE[HY000]: General error: 1021 Disk full (/rdsdbdata/tmp/#sql_bec_0.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")

Hi all.

I am getting this error:

SQLSTATE[HY000]: General error: 1021 Disk full (/rdsdbdata/tmp/#sql_bec_0.MAI); waiting for someone to free some space… (errno: 28 “No space left on device”)

Any suggestions please for what I need to do?

Thank you

Even if it sounds silly: Is it possible that there is no disk space left on your server and as a result mysql isn’t able to save anything?
