New -s option for zpool status

With SRU 30 of Solaris 11.4, the zpool command got a new option for the status command. You can now get some additional information about the devices. This blog entry is somewhat related to the one from yesterday as you can now check easily how you have configured your pool with the option i showed there.

• AUNIT:This column shows the allocation unit used by the device. So you don’t have to zdb the pool in order to search for the ashift value.
• LSIZE: Logical sector size reported by a disk.
• PSIZE: Physical sector size reported by a disk.

The next values are boolean, however they are only shown if they are actually true.

• SLOW: Is a disk or a vdev marked as slow.
• RPAIR: Is a repair currently running for a vdev or a disk.
• RSLVR: Is a resilver currently running for a vdev or a disk.

The columns READ,WRITE and CKSUM stay the same. From my point of view the AUNIT is the most interesting addition to the status-subcommand of zpool because now it’s quite easy to check how the zpool was created.
