# ibrix_migrator -A -f ifs2 -r ' name = "*.jpg" ' -S T2 -D T1
For example, if tier 1 is filled with .doc files to 70% capacity and tier2 is filled with .jpg files to
80% capacity, then tiering might terminate before it is able to fully "swap" the contents of tier 1
and tier 2. The files are processed in no particular order; therefore, it is possible that more .doc
files will be encountered at the beginning of the job, causing space on tier 2 to be consumed faster
than on tier 1. Once a destination tier is full, obviously no further movement in that direction is
possible.
These rules in these two examples are ambiguous because they give rise to possible conflicting
file movement. It is the user’s responsibility to write unambiguous rules for the data tiering policy
for their file systems.
