Working from a remote linux machine on a zfs fs that is an nfs mounted
share (set for nfs availability on zfs server, mounted nfs on linux);
I've been noticing a certain kind of sloth when messing with files.
What I see: After writing a file it seems to take the fs too long to
be able to display the size correctly (with du).
I'm wondering if I should be using some special flags either on the
osol end or the linux end.
Here is an example:
rm -f file1; sleep 2;awk 'NR< 115000{print}' debug.log.6 >file1;du -sh
file1;sleep 3;du -sh file1;sleep 3; du -sh file1; ls -l file1; sleep 10; du -sh
file1
512 file1 <tested right away with du -sh>
512 file1 <checked after 3 seconds>
512 file1 <checked after 6 seconds>
<long `ls -l' just to show the size
du is failing to see>
-rw-r--r-- 1 nobody nobody 10831062 Feb 21 12:33 file
512 file1 <final check after 16 seconds>
Some time later the correct size becomes available... not sure how
much.

If that line above gets too wrapped to understand easily it is:
## clear any file
rm -f file
## brief sleep
sleep 2
## write a lot of lines to a file from some log file
awk 'NR< 115000{print}' debug.log.6 >file
## check the size right away
du -sh file
## sleep 3 seconds
sleep 3
## check size again
du -sh file
## sleep 3 more seconds
sleep 3
## check size again
du -sh file
## sleep a final 5 seconds
sleep 10
## Check on last time
du -sh file
