I am planning to move the pg databases from the internal RAID to external Fiber Channel over SAN.


Question is –


-With the db size being as big as, say, 30+GB, how do I move it on the new logical drive? (stop postgresql, and simply move it over somehow and make a link?)

-Currently, the internal RAID volume is ext3 filesystem. Any recommendations for the filesystem on the new FC volume? Rieserfs?


DBs are 7.4.1(RH9), and 7.2.3 (RH8).



Appreciate any pointers.
