If you follow the posts on this site, you'd have noticed my issues with the recent Hardy upgrade. While I thought they'd been fixed in my fstab, this was apparently not the case. When I rebooted the machine next, I couldn't even get to the shell as I encountered the message - Unable to execute /bin/sh - Permission Denied.
If you run into an error message along the lines of
mount: /dev/sdb2 already mounted or /media/data1 busy, and the disk has not been mounted, it usually indicates that something has locked it intentionally to prevent it from being mounted. In my case, the culprit was dmraid, a RAID management tool that I am not using any more. Uninstalling the package did the trick. (Removing the array configuration from dmraid would probably have sufficed)
So, what do you make of the error message in the title? I ran into this while coding in PHP and thought that I must've installed a dodgy version of PHP or might have been h4xx0r3d. But a quick google revealed that PAAMAYIM_NEKUDOTAYIM represents the
:: operator in Hebrew.
