I'm getting this message "The pool is formatted using a legacy on-disk format."

[netman06]

Hello,

I was running a zpool status -v command and recevied this message.

The pool is formatted using a legacy on-disk format

I then ran this command zpool get version Volume1
NAME PROPERTY VALUE SOURCE
Volume1 version 15 local

Then I found some information discussing features, also ran this command.

Volume1 feature@async_destroy disabled local
Volume1 feature@empty_bpobj disabled local
Volume1 feature@lz4_compress disabled local
Volume1 feature@multi_vdev_crash_dump disabled local
Volume1 feature@spacemap_histogram disabled local
Volume1 feature@enabled_txg disabled local
Volume1 feature@hole_birth disabled local
Volume1 feature@extensible_dataset disabled local
Volume1 feature@bookmarks disabled local

So, if I'm not using any of these features, do I need to upgrade my disk format.

Because I currently running FreeNAS FreeNAS-9.2.1.3-RELEASE-x64 (dc0c46b)

Any suggestion would be helpful to me, so that I can make a good decsion as to what I need to do here.

Take Care,

-Mike

So you *definitely* should upgrade your pool. If you've been using 9.2.1.3 for a while (and I'm sure you have) you should go to the command line and upgrade your pool with "zpool upgrade <poolname>".

You also shouldn't be using 9.2.1.3. In fact, nobody should be running anything less than 9.2.1.7 because of a Samba vulnerability.
