I was trying to shrink the device( a lvm2 volume ) i am going to replicate. I am using LVM2 with XFS, does it mean I have to use lvresize insteadof resize2fs?
because when I use resize2fs on a volume(lv1) which is 256M, it shows:
-bash-3.00# resize2fs /dev/VG01/lv1/ 128
resize2fs 1.35 (28-Feb-2004)
resize2fs: No such file or directory while trying to open /dev/VG01200504181802p
roNASVG/lv1/
Couldn't find valid filesystem superblock.
however when i run lvreize, it shows:
lvresize /dev/VG01/lv1 -L 128M
WARNING: Reducing active logical volume to 128.00 MB
THIS MAY DESTROY YOUR DATA (filesystem etc.)
Do you really want to reduce lv1? [y/n]:
If I remember right, the size of XFS filesystem can not be reduced? Does it mean it is better to put metadata in other device instead of internal??

Yes, you can use an existing filesystem if you have
a) 128 Megs free for each metadata-device or
b) are using external metadata
you can use an existing filesystem, yes. Did you shrink your existing
filesystem by 128 M as explained here:
