TIA to all that can give some insight. 

 

Relavent setup info:

NetApp DS4246 

Exos x18-18TB-SATA

Exos x20-18TB-SATA

*Connected using the transposers in the drive tray

 

I recently noticed that a few of my drives were not reporting temperature.  I believe it's the transposers that are not passing along the data, and are bad.

 

However, if I swap out the transposer unraid does not recognize the same drive with a new transposer.  While the model/serial is recognized in the drive name, the last digits are some form of a serial to the transposer (not the serial that is on the label of the transposer though).

 

Is there any way to swap out these transposers without having to resilver the drive?

 

Thanks!

You should be able to do a new config or re-import the pool, if it's just a pool, also those enclosures typically work best without transposers, showing all SMART info and temps.

Thanks for the reply.

 

Sorry I should have stated, the drives are in ZFS pool. 

 

The entire pool is not lost when trying to swap the transposer, just the single drive is not recognized. unraid views the drive as a new/different drive.  Thus wants to resilver a degraded state. 

 

The drives are SATA, when I tried to use them straight into the NetApp, they are not recognized, I had to use the transposers.  From what I've read only SAS drives in these disk shelves will be recognized without transposers.

 

Thank you!

I know of other user that use SATA without interposers, but not sure if it's the same Netapp model.

You can still re-import the complete pool with the new ID for one device, are you on v6.12 or v7.0?

Thanks JorgeB!

From my luck, drives weren't being recognized without the transposers. However, I will re-test it.

 

I am not familiar with re-importing with the new ID. I would appreciate any information you could point me towards, I will try and look in the guide. 

On v7.0.0rc2

 

 

To reimport a pool

stop the array

click on the pool and then "Remove Pool"

back on main, add a new pool with the same name and number of slots

assign all pool devices, leave the fs set to auto

start the array

Wow, that's incredibly simple.  No data loss, or need to back up configuration of any form?

 

 

Yep, it will just import the existing pool, assuming all is OK with it and the devices

@JorgeB I just wanted to come back and confirm that your solution worked, exactly as you stated. While following your steps, I was able to swap in transposers without issue. Now all drives are reporting temps.

 

Thank you so much.
