checking filesystem has largefiles set

Debbie Downing_2 — Fri, 17 Nov 2006 05:41:56 GMT

Hi

Can anyone tell me the command to use to see if largefiles has been applied to a filesystem (for oracle files)... and if largefiles is not set how to configure largefiles without having to recreate the filesystem.

Thanks in advance.

Debbie

Debbie,
1. cat /etc/fstab

2. Depends on your filesystem:
See "man fsadm"
Example:
fsadm -F vxfs -o largefiles /mount-point

Hi Debbie:

To check the status of a filesystem you can do:

# mkfs -m -F vxfs /dev/vgXX/lvolN

(or)

# fsadm -F vxfs /mountpoint

To enable 'largefiles' do, where you do *not* have OnlineJFS installed:

# umount /mountpoint
# fsadm -F vxfs -o largefiles /dev/vgXY/rlvolN

...note the raw device.

...or, if you have OnlineJFS:

# fsadm -F vxfs -o largefiles /mountpoint

Regards!

# fsadm /var
fsadm: /etc/default/fs is used for determining the file system type
largefiles

Hi (again):

Examining '/etc/fstab' for 'largefiles' does *not* provide a way to determine that actual filesystem state.

The 'largefiles' or 'nolargefiles' argument of 'fstab' is used only at mount time. If 'nolargefiles' is specified *and* there are largefiles found in the filesystem, then the mount fails. If 'largefiles' is specified but no largefiles are found, the mount succeeds, too.

Regards!

The easiest method is to use bdfmegs -v (attached). It provides a cleaner look at mounted filesystems.

hi,

To check the filesystems applied with large files u can use the following command

mkfs -m filesystem-name

To Convert a JFS file system from a nolargefiles file system to a largefiles file system:

fsadm -F hfs -o largefiles /dev/vg02/lvol1
