Well, the device reports that block provisioning is disabled (lbpme=0) which explains why discard is not enabled by default. Oddly enough your device does not report an UNMAP granularity. I'm trying to figure out how your discard granularity ends up being 0 given that your device reports a physical block size of 4096.
I have inserted 2 other m.2 SSDs into the adapter: There was no problem with these, esp there was no warning about discard_granularity, or a RIP. First SSD back in: RIP is back, too. I would guess the first SSD is bad. Sorry for all the trouble. I should have tried another m.2 SSD first. Just for the record, this is what smartctl -x reports about the bad SSD: ------------------------------------------------------------------------------- root@dpcl082:~# smartctl -x /dev/sdf smartctl 7.4 2023-08-01 r5530 [x86_64-linux-6.7.6-raw] (local build) Copyright (C) 2002-23, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Number: SAMSUNG MZVLB1T0HALR-000L7 Serial Number: S3TPNX0K917992 Firmware Version: 5L2QEXA7 PCI Vendor/Subsystem ID: 0x144d IEEE OUI Identifier: 0x002538 Total NVM Capacity: 1,024,209,543,168 [1.02 TB] Unallocated NVM Capacity: 0 Controller ID: 4 NVMe Version: 1.2 Number of Namespaces: 1 Namespace 1 Size/Capacity: 1,024,209,543,168 [1.02 TB] Namespace 1 Utilization: 1,015,982,354,432 [1.01 TB] Namespace 1 Formatted LBA Size: 512 Namespace 1 IEEE EUI-64: 002538 8981be5959 Local Time is: Tue Mar 5 08:29:01 2024 CET Firmware Updates (0x16): 3 Slots, no Reset required Optional Admin Commands (0x0017): Security Format Frmw_DL Self_Test Optional NVM Commands (0x001f): Comp Wr_Unc DS_Mngmt Wr_Zero Sav/Sel_Feat Log Page Attributes (0x03): S/H_per_NS Cmd_Eff_Lg Maximum Data Transfer Size: 512 Pages Warning Comp.
