Re: limit on filesystem size?

["Steve Costaras" <stevecs@oceanbay.com>]

How are you planning on creating this filesystem?    I have tried
creating 2TB filessystems here for a while and have had little or no
luck w/ Solaris or linux.  Using Disksuite for solaris and LVM and MD for
linux no luck.  I have not tried veritas VM yet but even calling up SUN
the answer is that 1TB is the limit per filesystem currently under solaris 8
& 9

Linux is really around 980GB or so where it starts to flake out.
