Problem with Mnesia directory disappearing in RabbitMQ

I copy-pasted and cleaned up all those numbers, which are character codes, and this is what I get:

$ erl

> io:format(“~s”, [[47,117,115,114,47,98,105,110,47,100,102,58,32,226,128,152,47,100,97,116,97,47,100,97,116,97,47,114,97,98,98,105,116,109,113,47,109,110,101,115,105,97,47,114,97,98,98,105,116,64,103,101,121,101,115,45,112,107,45,108,118,48,54,45,109,113,48,50,226,128,153,58,32,78,111,32,115,117,99,104,32,102,105,108,101,32,111,114,32,100,105,114,101,99,116,111,114,121,10]]).
/usr/bin/df: â: No such file or directory

so it seems like you have no /usr/bin/df, which RabbitMQ uses for disk monitoring. You can check the code of the disk monitor here:
