Hi, I'm new to XFS, I have RAID-10 array with 4 disk, when I check with xfs_info, the information print like this. $ xfs_info /var/lib/mysql meta-data=/dev/mapper/vg_catalystdb01-lv_database isize=256 agcount=16, agsize=1600000 blks = sectsz=4096 attr=2, projid32bit=0 data = bsize=4096 blocks=25600000, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 log =internal bsize=4096 blocks=12500, version=2 = sectsz=4096 sunit=1 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 Is it possible to change `sectsz` value to 512 without re-format it? Or any suggestion? I have issue with current sector size, my TokuDB engines[1] can't start because of this.
