Current calculation fails when there are many same type of devices with the testing device, eg sda1 sda2 ... sda10, sda11, sda12 .. $(grep sda1 /proc/partitions) gets multiple numbers. $ grep ram1 /proc/partitions 1 1 10485760 ram1 1 10 10485760 ram10 1 11 10485760 ram11 1 12 10485760 ram12 1 13 10485760 ram13 1 14 10485760 ram14 1 15 10485760 ram15 $ grep -w ram1 /proc/partitions 1 1 10485760 ram1 Fix this by adding the -w option to grep to match the block device exactly.
