How was was logical volue formatted?

Yashodhan Deo — Mon, 18 Oct 2004 00:26:23 GMT

I have a logical volume with vxfs formatting. I would like to know what all options like largefiles/nolargefiles/suid/nosuid etc were used while formatting a logical volume. I dont trust the /etc/fstab file. Any other way I can get the information.

Try man page
man newfs_vxfs
man mkfs_vxfs

Hi Yashodhan,

Some of the options (like suid/nosuid, minfree etc.,) are mount points. Some of them like largefiles, blocksize etc., are filesystem format options.

Simple 'mount' command shows you all the options used to mount the filesystems.

For the formatting options 'mkfs -m /dev/vgxx/lvolx' should show them. Do not forget to specify '-m' option with mkfs command.

HI Yashodan,
You can use
# fstype -v /dev/vgxx/lvolx
command to know more about the FileSystem attributes.

BTW: FSTAB indicates all correct information and no harm in believing it.

Hope that helps.
Regards,

Yashodhan,

Looks like these answers didn't help you. Can elaborate your question a bit more?.

newfs -m -F vxfs /dev/vgxx/rlvolx --> will give you the options that were used to create the file system.

mount -p will give you the options with which the the lvol is mounted.

Hope this helps.
