Yousty Posted March 16, 2022 Share Posted March 16, 2022 (edited) In the middle of last night I received an error email from my server: Quote Event: Unraid Cache disk message Subject: Warning [NAS] - Cache pool BTRFS missing device(s) Description: Samsung_SSD_960_EVO_500GB_S3X4NF0JA14460X (nvme1n1) Importance: warning I logged into unraid gui this morning and it still showed the drive listed on the main screen but no temp was displayed. I could browse the folders/files located on it but I couldn't copy or modify any of them. So I tried restarting Unraid and now it doesn't even display that drive anywhere, but it still shows my other nvme drive that has a VM running on it. I powered down and decided to upgrade my motherboard BIOS to the latest just in case and I even swapped my 2 nvme drives on the motherboard slots to make sure it wasn't a bad slot but Unraid still isn't seeing my cache drive, but my Asrock BIOS does see both nvme drives. Please help! Here is my diagnostic log: nas-diagnostics-20220316-1012.zip Edited March 16, 2022 by Yousty Quote Link to comment
JorgeB Posted March 16, 2022 Share Posted March 16, 2022 Only one NVMe device is being detected by Linux, this is not an Unraid issue, though strange if the BIOS is detecting both, try booting with just one of them, in the same M.2 slot. Quote Link to comment
Yousty Posted March 16, 2022 Author Share Posted March 16, 2022 (edited) That was the first thing I tried. I removed the VM nvme and swapped the cache nvme to the other slot on my motherboard and booted. BIOS listed the drive when I went to the Storage tab, but when I booted into Unraid it's not there. Here is a picture I just took from BIOS that lists the missing 960 nvme. Edited March 16, 2022 by Yousty Quote Link to comment
JorgeB Posted March 16, 2022 Share Posted March 16, 2022 Likely a device problem, no signs in the log of the second NVMe device. Quote Link to comment
