Ok, 

On the original FS the files are fine.

EX:

# ll /usr/local/virtual/jdeciantis\@celebrityaccess.com/.Trash/
total 388
drwx------    6 1001     maildrop      224 Jan 29 10:05 .
drwx------    9 1001     maildrop      344 Feb 27 18:12 ..
drwx------    2 1001     maildrop   389600 Jan 29 10:03 courierimapkeywords
-rw-r--r--    1 1001     maildrop     2460 Jan 29 10:05 courierimapuiddb
drwx------    2 1001     maildrop     3128 Jan 29 10:05 cur
-rwx------    1 1001     maildrop        0 Jun 23  2005 maildirfolder
drwx------    2 1001     maildrop       48 Jun 23  2005 new
drwx------    2 1001     maildrop       48 Jan 29 10:05 tmp


I can't seem to remount the FS readonly for fsck, I get this:

# mount -r -o remount /
mount: / is busy


Is there a way around this? FYI: The machine is remote. 

Thanks for your help!
