ioprof fails when creating traces < 3 seconds long

~/ioprof> ioprof.py -m trace -d /dev/nvme0n1  -r 2
Mapping files to block locations                
Creating tarball nvme0n1.tar
tar -cf nvme0n1.tar blk.out.nvme0n1.*.gz fdisk.nvme0n1  &> /dev/null
ERROR: failed to tarball nvme0n1.tar

(this only happens on the python version)

Great catch! Indeed the tool breaks up long blktrace runs into 3 second bursts to minimize the potential for overrunning the buffer. I’ll investigate.

Thanks,

This should be resolved on the latest commit. I'm closing out this issue. It was tested on Ubuntu 16.04 LTS and Ubuntu 18.04 LTS
