I just installed a RocketRaid 2760A.  It was working great till 2 drives just have no file system anymore.  I took them out and tried it on another computer and verified it was correct.  My onboard controller is failing is why I bought this card.  I'm scared to rebuild because if I loose one more drive I will loose a lot of DATA.  Any help would be appreciated.  I got the controller working by fallowing the info in these forms.  The 2 drives have no smart attribute failures.  Just up and lost their file system.

 

Thank you in advance,

Here is what my array screen looks like.  I swapped all the drives back to the failing internal controller because atleast it's stable when it boots up...It sometimes doesn't reconized drives on boot but when it does it works fine.

Here is another screen shot

What should I do to recover the drives?

Please post your diagnostics: Tools -> Diagnostics

Don't know how much this will help.  The server has been rebooted several times since the problem occurred and I switched back to the internal controller, which if failing, till it is figured out.

 

Thank you for your time and help,

Rocketraid use a Marvell chipset and not recommended for unRAID anymore, one of the issues is that they tend to drop disks, and while the diags are after reboot so and can't say for sure, problem was most likely controller related, as to the data doing a new config *should* get both disks back, but before doing that and unless you're sure the filesystem for disk3 and 4 is reiserfs, change it to auto on both disks and try to start the array again, then post new diags.

Wow, I just spent 618$ on this this thing based on it was the only 24 drive controller I found...I didn't see the not recommended anywhere.  I have no idea if I can return it or not...Is there another 24 drive x16 2.0 card out there?  The are reiserfs as these were the first DATA drives I bought for unRAID when I built the system.  I've been thinking of getting another drive and slowly converting them to xfs.  The server has been rebooted dozens of time and I also checked the disks on another computer and they are bland as the day they were bought...I think the non-persistent logs on unRAID is the only down fall of the OS... I have so much trouble diagnosing problems because I usually find out when the server is unresponsive I had a problem.

 

What do you mean by new config? 

 

Here is the diags after the array stop and restart

 

Thank you again,

I've done more research and was wandering what you though of using one of these

LSI SAS 9207-8i 8-port, 6Gb/s SAS+SATA to PCI Express Host Bus Adapter

with one of these

Intel RAID Twenty-four port Expander Card RES2SV240

and I just try to return that Rocket Raid thing.  I read that these cards seam to be rock solid with unRAID.

I just noticed...The Data from those 2 disks are all missing.  I know the Parity is good as the last parity check says so.  I thought the data was suppose to be accessible when the disks were disables using the Parity...Unless I'm missing something...

LSI HBAs are the recommended controllers, with 8 or 16 ports, not sure about 24, though you can use a SAS expander if needed.

FS is still set to reiserfs on disk3 and 4, and no reiser filesystem is being found, either those disks are not reiser or your parity is invalid.

-Tools -> New Config -> Retain current configuration: All -> Apply
-assign any missing disk(s)
check "parity is already valid" before starting the array
-start the array

 

If disks still unmountable post new diags, if they mount do a parity check.

How could the parity get invalid?  I just lost only Data 3 and 4 disks all others are fine?

I don't know, maybe if you had the previous syslogs I could see what happened.

After doing a new config, and unless something very wrong happened previously, you should get the data from disks 3 and 4 back.

DO NOT USE THIS UTILITY THINKING IT WILL REBUILD A FAILED DRIVE - it will have the opposite effect of making it impossible to rebuild an existing failed drive - you have been warned!

 

Is a warning I get from New Config

This is why I don't like the way unRAID does it's logs.  I need to find a way to make my logs persistent eternally.

YOU ARE AWESOME!!!!  I decided to trust you and you were right.  There is nothing wrong with the Data on the Disks...They were just disabled!!  THANK YOU!!!!  I will be MUCH more careful when I change critical hardware.  Community will be asked first before ANY upgrade!  Please add the Rocket Raid 2760A as NOT working...It almost made me loose data!!!!
