Thread: new journaling system in OSX

new journaling system in OSX

From

Date:
I just upgraded to system 10.2.2 for Mac OSX. I saw in
the documentation that they have added a new
Journaling File System so on a lark I turned it on.

I see that when postgresql is starting up it now takes
it quite a while (from about 2 seconds to 12-15
seconds). I don't see anything else 'weird' however
does anyone have any experience with this kind of
behavior?

I guess this is more of a 'heads up' message. I would
hate to see youse guys actually release a version that
had major problem with OSX.

Wow, that's a pretty dramatic change.  Journalling file systems do cause
extra overhead when we fsync the data to the disk, but I wouldn't expect
that magnitude of change, and I wouldn't expect it to be during startup.

Speaking of which, I can't seem to get my postgres 7.2.1 to run at all on my
new OS X 10.2 system.  That works fine on 10.1.5.  Do I have to install a
new version of postgres?

You should try 7.3beta.  It will work on that OS.

There is a problem with the 'make' of 7.2.x in 10.2

There is a fix that requires commenting out a few
lines.

search the 'bugs' area and you will find the thread.
