Re: New RAID-5 800GB array, wich fs ? wich stripe block size ?

[Bernhard Dobbels <Bernhard@Dobbels.com>]

800 GB in one filesystem is possible, but I think it'll make life easier 
if you have multiple partitions which you can mount wherever you want.

Technically speaking, I prefer the LVM2 solution on which you can make 
and resize partitions on the fly.

I must admit I lost my raid5 with LVM2. The cause will probably have 
been my fault, although I don't know what I did wrong, so I suggest if 
you have critical data, a backup on another medium is still advised.

Good luck.
