I have an unRAID version 6.6.6 system with an I/O Crest 4 Port SATA III PCI-e 2.0 x1 Controller Card Marvell 9215 (based on the Marvell 88SE9215). When I tried to upgrade to version 6.7.0 I lost 3 drives which were attached to this controller card.  I reverted back to version 6.6.6 and the drives reappeared on the array.

 

I am reluctant to try going to 6.7.2 because I don't know if this problem still exists, plus I've been aware of the posts on database corruption issues. My question is this: should I replace the controller with a non-Marvell based controller and try again? If so, what are the recommended controllers for SATA drives that should not have this problem with 6.7.x? 

 

Thanks

Did you try the solution of adding extra boot parameters as many have found fixes this issue on the 6.7.x series of releases.

Where would I find it?

Thanks johnnie.black. I still am uncertain if I should scrap this controller card for a non-Marvell based one. I see SAS controllers out there but I'm not familiar with them.  And if I change my controller will all the existing drive assignments be preserved?

It usually will be plug-and-play. There are some controllers out there that truncates the serial number, then you will need to readd. You can ask around on the forum for recommendations.

Here is one I am looking at currently LSI Broadcom SAS 9300-8i 8-port 12Gb/s SATA+SAS PCI-Express 3.0 Low Profile Host Bus Adapter https://www.amazon.com/dp/B00DSURZYS/ref=cm_sw_r_cp_apa_i_3c3fDbFCRSQST

SAS 9300-8i

That one is a good option and plug 'n play
