Question 2. To decrease in size a file system, the command lvreduce is used, what is the difference in between the two ways showed next? (Assuming that the file system size now is more than 2 Gb):
1- lvreduce SENECA/LUX -L2G
2- lvreduce SENECA/LUX -L -2G
Using the first command, the file system size will be 2 Gb, while in the second way we are subtracting 2 Gb from the current size, if we don't know the current size we won't be able to know what size the file system will be exactly.
