RAIDZ2 replace disk problem

[TombR]

Hi All
I have a problem with REPLACEMENT disk (WD GREEN after WD RED the same capacity). Tested on linux S.M.A.R.T. is OK, no errors, cleared data by dd on linux. On disk no bad sectors (replacement disk). How to online this disk?
'zpool online main 1228652766114763662747' is no effect. From GUI too.

Please help me with this situation. Please forgive me for my english.
Thanks for Yours help.

Hi @TombR.

I don't have a concrete solution for you off hand but I would suggest a few things.

First, post your system specs. Folks are more likely to be able to help you if you do. Feel free to edit your post above and include your FreeNAS Version and all all relevant hardware. It is better to be more specific.

Also, I think it is generally best to deal with the system via the UI exclusively where possible. The reason is that FreeNAS makes use of various settings and flags of ZFS and the OS that you might not be aware of. Even if the command seem to work there may be unintended side effects.

Finally, if you haven't done so, check out the User Manual for your version of FreeNAS. They manual contains documentation for how to replace a bad disk which might be sufficient to solve your problem.
