granular_orchid_nitrogen Posted March 9, 2023 Share Posted March 9, 2023 Hi guys, I'm trying to replace one of my cache drives in the cache pool and coming up with some issues. I've tried to raid 1 the pool (initially only had one drive, now have two) and it doesn't look like it mirrors it and I see an error of: critical medium error, dev sdb, sector 14577600 op 0x0:(READ) flags 0x80700 phys_seg 13 prio class 0 I was hoping to mirror them and then just add another drive and swap my usb drive out for cache1. I then looked up how to move the cache shares back to the array and it showed to set the Use cache pool (for new files/directories) to "Yes". I did that, but still see the shares on the cache drive. Is there an easy or better way to replace the cache drive efficiently? Thanks for the help. Quote Link to comment

granular_orchid_nitrogen Posted March 10, 2023 Author Share Posted March 10, 2023 Attached. Thanks, I'm also seeing some of the data in raid 1 and some in single mode. I'm trying to remove the USB and just have the nvme. I have another nvme drive that I was planning on replacing the usb with. tower-diagnostics-20230310-1117.zip Quote Link to comment
JorgeB Posted March 10, 2023 Share Posted March 10, 2023 Because of the USB bridge cannot see SMART for the SSD, but it does appear to be failing, if that's the case best to just try to copy everything you can to another place and then start over with the new cache devices. Quote Link to comment
granular_orchid_nitrogen Posted March 10, 2023 Author Share Posted March 10, 2023 How can I move this data to the array temporarily? Quote Link to comment
JorgeB Posted March 10, 2023 Share Posted March 10, 2023 Try to copy it using you favorite tool, if you don't have one try the Dynamix file manager or Midnight commander. Quote Link to comment
granular_orchid_nitrogen Posted March 12, 2023 Author Share Posted March 12, 2023 Ok, I ended up swapping out the nvme drives and it's working....but I have a question. I copied the data back to cache and tried converting to raid 1. It shows it's in raid one, but how can I verify the folders I moved back over are raided also? tower-diagnostics-20230311-2002.zip Quote Link to comment

Everything on cache is using raid1, including all folders you've moved back. Quote Link to comment
