confirm mount options used

[Joseph Hoh]

If I use certain mount options when mounting a file system.

such as:
mount -F vxfs -o delaylog,mincache=direct,convoync=direct,nodatainlog /dev/vgxx/lvxx /mountpoint

How can I confirm these options actually took effect?

Hi
you can use mkfs with -m options to check if all the options you have selected have been applied

it's

mkfs -m /dev/vgXX/lvolY

Hi Jeff:

Firstly, if the mount options were misspelled, for instance, the 'mount' command would be rejected.

Secondly, if some of the options were not allowd, for instance because you didn't license OnlineJFS, then the 'mount' would be rejected.

Lastly, for a "warm-fuzzy', you can see what is mounted with what options by doing:

# more /etc/mnttab

Use mount -v or check /etc/mnttab, which lists all mounted file system of the client

more /etc/mnttab
