Replacing a drive in RAIDZ1

[Craig321]

Hi,

First off, yes I realise RAIDZ1 can be dangerous, particularly when replacing drives!!

Anyway, I have noticed one of my 1.5TB drives has started picking up bad sectors and I've had a couple of warnings/errors from my regular SMART scans. Nothing vital at the moment and everything is running fine, but the disk is something like 7 years old now so I figure it's time to replace.

I assume I can just pull the disk in question out and pop the new one in and it'll rebuild onto the new disk? It's a 4 disk array.

There isn't currently space to attach the new disk and run the zpool replace command(s).

Also, should I be doing anything in particular after replacing the disk? A scrub? Anything else?

Thanks.

Be sure to follow the instructions in the Guide for your version of FreeNAS. There will be a section on replacing a failed drive.

Ah! Should have done that first - thank you.

For anyone that comes across this thread, the instructions are here for the latest FreeNAS (at time of writing): http://doc.freenas.org/9.3/freenas_storage.html#replacing-a-failed-drive

Tis easy enough. Take the disk offline in the GUI, replace it physically, then use the replace button in the GUI
