Hi, I suspect you're missing this fix: https://gitlab.com/lvmteam/lvm2/-/commit/fa496513010976aac21584b5081529b76462f9a9 To work around the problem, you can disable the fs checking in lvresize with '--fs ignore', which tells lvresize that you have already properly resized the fs.

The 1.00 TB is not what I’ve requested. And If I try another size, it tells me that I’ve asked for a null size : > lvresize -L64T /dev/vg_raid/datas > File system btrfs found on vg_raid/datas. > File system size (62,00 TiB) is larger than the requested size (0 ). > File system reduce is required and not supported (btrfs). > > So I really don’t get what’s going on here.
