This is a small desktop / short tower case which is connected to a couple of tape libraries.

This post replaces a previous post.

zpools

Well. That’s not good.

[dan@tape01:~] $ zpool status
  pool: zroot
 state: DEGRADED
status: One or more devices could not be opened.  Sufficient replicas exist for
	the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

This appears to be a three-way mirror with one missing drive. Let’s get rid of that drive from the configuration by removing it, logically.

First, detach the device:

[dan@tape01:~] $ sudo zpool detach zroot 91228858897502323
[dan@tape01:~] $ zpool status
  pool: zroot
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
	still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
	the pool may no longer be accessible by software that does not support
	the features. See zpool-features(7) for details.
  scan: none requested
config:

	NAME        STATE     READ WRITE CKSUM

Do the zpool upgrade:

[dan@tape01:~] $ sudo zpool upgrade zroot
This system supports ZFS pool feature flags.

Enabled the following features on 'zroot':
  large_dnode
  device_removal
  obsolete_counts
  zpool_checkpoint
  spacemap_v2

If you boot from pool 'zroot', don't forget to update boot code.
Assuming you use GPT partitioning and da0 is your boot disk
the following command will do it:

	gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0

We need to update the boot code so boot will always work. Do every drive you might boot from. This means every drive.

partcode written to ada0p1
bootcode written to ada0
[dan@tape01:~] $ sudo gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1
partcode written to ada1p1
bootcode written to ada1
[dan@tape01:~] $ zpool status

Let’s do a scrub, just because we can.

[dan@tape01:~] $ sudo zpool scrub zroot
[dan@tape01:~] $ zpool status
  pool: zroot

All good now.
