Maximum Veritas Filesystem size question
2007-12-24 21:59:00
I need to create a 2 TB filesystem and perform some application tests on it.
I'm using Solaris 8, Veritas Volume Manger 3.1 and Veritas Filesystem 3.4. I
have latest patches applied. I was able to create a 2.8 TB veritas volume,
but when I tried to create the filesystem, I got the message that the
maximum size is 1TB. I created an 1 TB version 4 vxfs on that volume (with
largefiles support) without any problem, but I would like to overcome this
limitation if possible. Checking Veritas documentation I found this:
Version 4 is the new and default VxFS disk layout. This disk layout
encompasses all file system structuralinformation in files, rather than at
fixed locations on disk, allowing for greater scalability.It adds support
for:
- files up to 2 terabytes
- file systems up to 1 terabyte
- Access Control Lists
The Version 4 disk layout was designed to allow the file systemto scale
easily to accommodate large files and large file systems.
My question(s) is(are):
1. What is the point to support files up to 2 TB and filesystems up to 1 TB
only. I never heard one could span a file over multiple filesystems.
2. Are there patches or other filesystem layouts (like Andrews File System
or UFS+) to go over 1TB limit ?
