Hi all,

I need some help.   I self compiled rsync 3.0.4 on Mac OSX 10.4 (Tiger)

Trying to run the command below...
rsync --dry-run -aucvvvX --log-file=fly-dryrun.txt /Volumes/airplane/
/Volumes/plane/flight
when running the above command, rsync idles with no action.   Anything
above 2 v's (-vv), rsync will sit at message below.

--------------------------
[sender] make_file(\#342\#200\#242Unused Art,*,2)
send_file_list done
--------------------------

1)  What's going on?   Is it because the source have probably 5000 sub
folders and total size is around 200 to 300 GB?

Doing a ktrace shows the info below...
18176 rsync    CALL  write(0x4,0x1804200,0x30)
 18176 rsync    GIO   fd 4 wrote 48 bytes
       "2008/12/16 13:25:43 [18176] send_file_list done
       "
 18176 rsync    RET   write 48/0x30
 18176 rsync    CALL  write(0x1,0x206000,0x14)
 18176 rsync    GIO   fd 1 wrote 20 bytes
       "send_file_list done
       "
 18176 rsync    RET   write 20/0x14
 18176 rsync    CALL  select(0x7,0,0xbfffc238,0xbfffc338,0xbfffc228)
 18176 rsync    RET   select 0
 18176 rsync    CALL  select(0x7,0,0xbfffc238,0xbfffc338,0xbfffc228)
 18176 rsync    RET   select 0

2)   Also, I'm not sure but I'm using the -c option to address this concern...

"If any existing files were touched and still corrupt, then --update would skip
any corrupt files even if they were inadvertently modified."

Did I do the correct thing in using '-c'.   Do a checksum instead of
doing mod time and size check with -u option.
thanks for  any guidance you can give.
