[clug-talk] File Systems

[John Jardine]

Hi Alex,

There is a significant chance that ext2 will be out of sync - but it's
not like it's guaranteed to fail.  

I haven't played here for awhile but ...
Dirty file-system buffers are flushed every 30 seconds by pdflush (by
default).  Therefore what you stand to lose is the data between the last
flush and a crash.

The Linux Programmer's Toolbox, p281, talks to this a bit.  There are
probably other better sources.

YMMV,
J.J.
