Hello I'm using ubuntu 12.04 and I'm trying to use Device::Blkid to find the relationship between a file and the UUID of the device where it is stored. Basically I gahter the device number by using stat and then I order (after setting up the cache variable, etc.) a Blkid_devno_to_devname($dev) and sometimes it works and sometimes it doesnot. When it works it returns '/dev/sda1' for instance but when it doesnot it returns an empty variable. Could I have a workarround to this issue ? Thanks in advance. I've forget to mention that the file /etc/blkid.tab is properly populated.

I'm very sorry for not answering any earlier. Your messages got a little lost between quite a bunch of things I need to do. Unfortunately, I'm not really sure what to answer. I have neither experienced problems similar to what you describe, nor do I have any idea of what is going wrong here. From what you are writing (cache populated) I guess that you are not currently running your code with root permissions. What happens when you do so? Can you find any common properties of runs where you get correct/incorrent responses? Thx Bastian

Hi there Thank you very much for your answer. In fact, the point that even if you run the code as root user you always need to run before a blkid in order to have the cache loaded. No way to get it loaded from the software itself. Thanks again Joaquín On 01/08/12 12:42, Bastian Friedrich via RT wrote: Show quoted text
