There is no problem moving a Squid cache around, as long as the
cache_dir line for the new location has the same L1 and L2
parameters.

ext2 does not have block fragments, and this problem does not occur
there.

Solaris can be tuned to mostly get rid of the problem by tuning the
filesystem to optimize for space. See the Squid FAQ.
