How can I tell if 10.20 is using online JFS?

[Debbie Fleith]

I'm having the same issue with lots of vx_inactive_thread processes running and have read the other forum responses that say they can be safely removed from the kernel, if the system isn't using online JFS or VxFS?.

How do I know if this server is using online JFS or VxFS?

# swlist -l bundle
will show if you have OnlineJFS (Advanced VxFS) installed or not.

Hi,

Try this:

# swlist -lfileset | grep JFS

HTH,

[Joseph C. Denman · Accepted solution]

agreed.

take a look at the /etc/fstab to see if you are vxfs or hfs filesystems.

caveat: you can config the filesystems to be vxfs without running on-line jfs. the swlist check is the better method.

Hi,

You can have JFS or vxfs filesystems without
having the on-line product. This product
allows you to do filesysetme changes without
actually un-mounting filesystems.
Unless you are only using HFS filesystems
leave the kerenl as it is.

Hi Debbie:

BTW, "VxFS" and "JFS" are used interchangeably. The filesystem type is "vxfs" (as opposed to the old 'hfs' type). JFS stand for Journaled File Systems and is a ported version of Veritas' code.

The "Online" version offers the ability to dynamically grow or shirnk filesystems; the ability to defragement them; and the ability to use additional mount options for improved filesystem performance.

To see if you have the Online version, simply do:

# swlist |grep -i onlinejfs

...if you have the online component, you will see:

B3928AA_APZ B.10.20 HP OnLineJFS (Advanced VxFS)
