I have three 2tb data drives(sdg, sdh, sdi), one 3tb parity drive (sdf), and one 250gb cache drive (sdj).  My main data drive (sdg) went bad (it contains most if not all of my data files).  My parity is still good, however, in replacing the bad 2tb data drive, I purchased a 4tb hd, forgetting about the size difference with the parity.  What's my best course of action?  Would it be best to replace the bad 2tb (sdg) with one of the other (sdi), letting the parity rebuild the drive then replace the 3tb parity (sdf) with the news 4tb?

 

any suggestions is greatly appreciated

There's a procedure called parity swap disabled that should work even in the 6.4 branch. I did this back on the 5.x series without any issue.

 

Here's the Wiki Page on it: https://wiki.lime-technology.com/The_parity_swap_procedure

 

I think there have been forum posts about it too.

Note, it's currently not working on v6.4, but it works on v6.3.x

Well that sucks. All these release candidates and scenarios like this does not work.

Yeah, I agree, especially with v6.4, there's been a lot of changes that broke some basic things, but it's still a pre-release and users should use it accordingly, I only use it on one of my servers (which acts as a backup server), all others are still on v6.3.5.

Thanks for the suggestions.  I'm currently at 6.3.5 so I should be good to parity swap disabled then.  Any precautions I should take?  My only concern is losing all my data since the drive that failed had all the data.

Just follow the procedure and keep the failed disk intact, if not completely dead it it may still be useful if anything else goes wrong.

My gui doesn't even show the failed drive exists.  It show unassigned.

It may come back after a reboot or power cycle.
