Hi, I created a zpool with a FreeBSD-14.0-CURRENT on February. With 15.0-CURRENT/14.0-STABLE from now I get the message: status: One or more devices are configured to use a non-native block size. Expect reduced performance. action: Replace affected devices with devices that support the configured block size, or migrate data to a properly configured pool. NAME STATE READ WRITE CKSUM zsys ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 nda0p4 ONLINE 0 0 0 block size: 4096B configured, 16384B native nda1p4 ONLINE 0 0 0 block size: 4096B configured, 16384B native nda2p4 ONLINE 0 0 0 block size: 4096B configured, 16384B native I use: nda0: <Samsung SSD 980 1TB ..> nda0: nvme version 1.4 nda0: 953869MB (1953525168 512 byte sectors) I cannot imagine, that the native blocksize changed. Do I really expect a reduced performance? Is it advisable to switch back to nvd? Kind regards, Frank -- Frank Behrens Osterwieck, Germany
