New Cache drive becomes read only during copy process

[MisterWolfe]

Good morning,

 

I have just installed an ssd on an existing unraid server (Version: 6.12.4). I'm attempting to copy the docker.img and appdata files from the array to the cache drive.  After a short period of time into the copy process I get an error message saying that the drive is read only and can't be written to.  I have tried copying using MC and a simply copy command from an ssh window and I get the same behaviour.

 

I want to be clear that the cache drive is initially readable and writable before I start the copy process. It becomes read only after I start the copy process and about 10GB of data has been copied.  I did notice that the SSD temperature went up to 55 degrees during the last copy.

 

The ssd is a Samsung 870 EVO.

 

I initially formatted the drive as BTRFS when I first got the error. I reformatted as XFS and I still get the error. The drive is formatted XFS currently.

 

The drive is connected via a PCIE expansion card. (Broadcom / LSI SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03)).

 

I've attached the diagnostics file.

 

Thanks for looking!

SSD is dropping offline, try different cables, probably best also to use the onboard SATA controller instead, since the LSI won't support trim.

Switching to onboard SATA controller resolved the issue. Thanks for replying.
