CKSUM errors; trying to replace with spare.

[danzg]

After a colleague bumped into the server, I'm getting this:

Code:

zpool status
  pool: raid-5x3
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
	attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
	using 'zpool clear' or replace the device with 'zpool replace'.

	spares
	  ada0      AVAIL   

errors: No known data errors

This means I should replace ada2p2, right?

I tried this:

Code:

zpool replace raid-5x3 ada2 ada0
cannot replace ada2 with ada0: no such device in pool

Should I do

Code:

zpool replace raid-5x3 ada2p2 ada0

?

Or can I do this from the GUI?

Or should I just 'zpool clear' ?

Thanks!

Use the WebGUI in 8.2 or 8.3 RC1.

Storage->Volumes->Volume status

Remove ada0
Replace ada2p2 -> Select ada0

The replacing seems to have worked; the new disk is now resilvered.

But now I have

Why does the new disk have that funky name? In the GUI it appears as ada0p2.
Should I detach it?

 

[danzg]

Also, in the GUI, some of the disks do not say 'member of...' (see attached.)

Do I need to be concerned about that?

Thats how things are from now on, best practices choice.
Detach the replaced one: ada2.
