Replace HDD in RAIDZ

[drnicolas]

I have 3 new 3TB HDDs which should replace old ones in an RAIDZ

As first Action, I offlined the first old HDD and replaced with a new one.

Using the GUI, I wanted now to 'online' the new HDD, but under devices, I get only a list of both reminaing old HDDs, not the new one.
using Status, I find my new HDD as a Long number and "was ada2.nop"
What should I do ?

zpool replace Name of pool Long number ada2

zpool online -e ada2

Okay, that worked; but only with the help of the cmdline. The Web-GUI seems not to be capable of doing the replace process.

But there remains a problem:
I am disappointed that the size of the pool stays at the same size as before.
I had once a pool with 696G; now all 3 HDDs have been replaced by 3TB models;
I would expect a new size of about 6G now.

I found somethig about a autoexpand-feature and activated this - no change

Merry christmas

Some more information:
hp-nas: ~ # zpool get expandsize vStorage
NAME PROPERTY VALUE SOURCE
vStorage expandsize 7.50T -
hp-nas: ~ #

Here you can see that there is a lot of space somewhere

Not 100% sure but I think an export and reimport of your pool will do the trick.
Merry Christmas!

autoexpand-feature work BEFORE replace disk.

zpool online -e my disk work AFTER replace disk even disk is online

"You can use the zpool online -e command to expand the pool's size when a smaller disk is replaced by a larger disk. By default, pool size is not expanded to its full size unless the autoexpand pool property is enabled. You can expand the pool size automatically when a smaller disk is replaced by a larger disk by using the zpool online -ecommand even if the disk is already online or if the disk is currently offline."

Thanky you. This worked for me.
I now have about 4.9T available.

Nevertheles, there seems to be a bug in Web-GUI.
