I've just stumbled across the SoftUpdates section in the FAQ, and was rather
surprised that I had never seen/heard of this feature before. Before
I mount any
partition using softdep, I thought I'd google, browse the archives, etc. for any
information about when/where they should be used.
Although I've found a plethora of information about soft updates, much of it is
either contradictory or incomplete.... I thought I'd ask here for clarification.
Is it always best to mount /, /tmp, /usr, /var, /home with softdep?
Under what curcumstances would it not be appropriate?
I have a few machines running a busy website (mounted on /var/www) and two
fairly-busy databases (mysql mounted on /var/www and postgresql mounted on
/var/postgresql).
All these machines have a perc5 raid controller using mfi driver.... does that
make a difference?
Running 4.1 MP + patches on all machines (just got the CDs.... and it's
awesome!)...dmesg below.
-George
p.s. Thanks for the new release! I'm already enjoying it! (and the poster!)
