I had this issue the other day as well I just reflashed cwm and it fixed my problem and hopefully yours as well.
E :Cant mount /cache/recovery/command
E :Can't mount / cache/recovery/log
E :Can't open /cache/recovery/log
These are to be expected, not sure about the last one.. can't remember... Is this an issue and not allowing you to do things or are you just concerned based on the messages?
Try turning off your phone, ejecting your sdcard and putting it back in and rebooting in recovery to try again?
