I am using Fedora 23, updated to 4.6.7-200.fc23.x86_64, using:

j.ski@localhost ~> df -T

I am trying to use xfs_io to read the contents of a file:

$ xfs_io /home/j.ski/-.truste.com

xfs_io> p
[000] /home/j.ski/-.truste.com (xfs,non-sync,non-direct,read-write)

xfs_io> pread -v 100 /home/j.ski/-.truste.com
pread64: Bad address

When I first tried this I got what I assumed were the files contents. BUT the next time I tried the exact same command, I get:

xfs_io> pread -v 100 /home/j.ski/-.truste.com
pread64: Bad address


Any idea(s)?
