Thank you. But I have a ... confusing output # /usr/sbin/tune2fs -l /dev/disk/by-label/TMP | grep "Block size" Block size: 4096
Filesystem blocksize, not sector size.
# lsblk -f -t /dev/disk/by-label/TMP NAME FSTYPE LABEL UUID MOUNTPOINT NAME ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA SCHED RQ-SIZE RA WSAME vgmain-vTMP /tmp vgmain-vTMP 0 512 0 512 512 1 128 128 0B
That is PHY-SEC = 512
But this is a late model 1T drive. Is there some way I can verify 4K sectors?
or conversely that it has 512b sectors?
hdparm -I WFM.
