Hey there,

The real world example is database files. What happens if a busy
mysql database making a lot of inserts has the fs brought down
uncleanly? Are sections of the file nulled or is the entire file nulled?
Some real-world experiences ...
I'm running a busy database-server running only mysql on it (dual
athlon-mp, 2GB ram).
The filesystem for the mysql-databases is xfs.
In the old kernel-2.4.19-days I had a lot of crashes of this machines
while the database was under load.
The worst things I've ever seen have been index-corruption, nothing a
mysqlrepair can't handle.
Never had nulled files or parts of files.
Since upgrading that machine to 2.4.25 everything runs smooth and
without crashes ... thanks for that great filesystem :-).
Regards,
Thomas
