block size: 512B configured, 4096B native all of a sudden
Date: Mon, 22 Apr 2024 14:52:19 UTC
I upgraded a RELENG_13 box from last March to one today to bring in some of the zfs bug fixes. But now I have this warning on a pool that was not there before. But the special devices (two 2TB samsungs) are 512 according to smartctl ? Any idea why this warning popped up on the pool all of a sudden ? the disks and pool have been the same for a year or so. # smartctl -a /dev/da4 === START OF INFORMATION SECTION === Model Family: Samsung based SSDs Device Model: Samsung SSD 870 EVO 2TB Serial Number: S6PNNM0W619793P LU WWN Device Id: 5 002538 fc36093bc Firmware Version: SVT02B6Q User Capacity: 2,000,398,934,016 bytes [2.00 TB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device # zpool status zbackup1 -v pool: zbackup1 state: ONLINE status: One or more devices are configured to use a non-native block size.
