make Journal file system

[Liadi]

I recently installed JFS 3.3 depot.
My question is how to create JFS type file system.

[Pete Randall]

When you newfs the file system, you specify the FS type:

/usr/sbin/newfs [-F FStype] [-o specific_options] [-V] special

I tried:
newfs -F jfs /dev/agtsab93/rlvol1

there is no such thing as jfs type.

[Massimo Bianchi · Accepted solution]

simply use the

newfs -F vxfs ....

if you want to choose the version (3 or 4) you must use the mkfs_vxfs command. Here follow and extract from the man page:

mkfs builds a file system with a root directory and a lost+found
directory (see fsck_vxfs(1M)). The file system can have disk layout
Version 2, disk layout Version 3, or disk layout Version 4. Version 2
supports dynamic inode allocation. Version 3 adds support for large
files and large UIDs. Version 4 adds support for Access Control
Lists. On HP-UX 11.1x systems, the default is Version 4. On HP-UX
11.0 systems, the default is Version 3. You can choose the disk
layout version with the version=n option (see below).

jfs stands for Journaled File System, and the HPUX implementation is the vxfs...

version 3.3 adds the version=4 layout of the file system.

Sorry, Liadi, I should have mentioned that the type is vxfs.

Thanks you all for your great response (and especially you pete for your 10 sec response) but something is not clear to me - before I installed the JSM 3.3 I created VxFS volumes, is that mean I had JSM? (I know I might be confused with those terms)

Liadi,

The base JFS (or VxFS) product is installed by default with version 10.x and beyond.
