Hi all,

 

I just upgrade to the nVidia 6.8 release build, and I don't see my cache drives/pool anymore. I have a 2x1TB SSD pool in raid1 which was working perfectly fine before this update. I installed the new release and now it's not there. All my other drives and files are present, but I can't get my cache pool back. Stopping array and checking the cache drives, they don't show up at all, just the 8 HDDs for my main array. They also don't show up under unassigned drives OR the missing drives (but one unassigned HDD I kept out of the array does show up) 

 

I went into BIOS and they're both there so the drives didn't suddenly die. Any help with this?

 

Thanks!

Please post the diagnostics: Tools -> Diagnostics

It looks like my SATA card isn't being recgonized. I just realized the three disks missing (one more unassigned drive I didn't notice earlier) are all attached to this SATA card: https://smile.amazon.com/IO-Crest-4-port-Controller-SI-PEX40057/dp/B00AZ9T264?sa-no-redirect=1

 

I rolled back to 6.6.7 and the drives are there (all 3) and I added both SSDs back to the cache pool and the data is there and everything is running fine...

 

Is there a compatibility issue with that controller/chipset?

 

-edit-

 

yup looks like this is the issue, the 88SE9230 Marvell controller has issues w/ Unraid... Will need to move my drives around, add non SSDs to my SAS card and add the SSDs to the native SATA ports .. Can I actually do this? Change controllers for my drives (swap 2 HDDs from onboard SATA to SAS card, and swap the marvell controller SSDs into onboard SATA ports? will that mess up any of the disk mappings?)

It's a known issue with those controllers, this can help sometimes:

Wow it worked! adding

and then updating to 6.8 and rebooting worked perfect

 

Thanks!!
