ZIL added as stripe

[spikk]

Hi,

I tried to add a Intel 313 ssd as a ZIL but there seems to be some kind of bug in the web gui so it extended the volume as a stripe instead.

Is it possible to delete this stripe?
Also, what command should I write, is zpool add log <disk_id> correct?

EDIT: this seems a bug in 9.1.0, and what I have found is that it is impossible to delete the stripe. Bad luck for me as I know have a 20 TB pool with a single point of failure :(
What is my best options, could I make this stripe into a mirror?

You should make the stripe into a mirror.. ASAP. As you've figured out, that's the only way to restore some kind of redundancy now.

Is that possible via the GUI or could you tell me how to do it via ssh (my trust to the GUI is gone now...)
Thanks!

To be clear, this is a stripe vdev and not a log vdev that is a single disk stripe? Regardless, output of:

Code:

zpool status

Be sure to use [code][/code] tags.

Currently this can only be done from the CLI.

The stripe is gptid/95a7f5d7-1a30-11e3-acc9-0025909515de
How do I make this a mirror?

EDIT: is this the way to go:
zpool attach SATA gptid/95a7f5d7-1a30-11e3-acc9-0025909515de <gptid of new disk>

I successfully converted the stripe into a mirror with the command written above.
One question, why are some disks listed by "da##" and the others by gptid?

Yes, that is the command. The cache vdev is using the whole disk and it doesn't have a partition table on it.
