Hi Rich, Currently we had btrfs-set-seeding for btrfstune. But btrfstune had more options: usage: btrfstune [options] device -S value positive value will enable seeding, zero to disable, negative is not allowed -r enable extended inode refs -x enable skinny metadata extent refs -f force to clear flags, make sure that you are aware of the dang...

...rypt. This will also be helpful when implementing btrfs support in grub for example. We can say the disk can be compressed/encrypted except for /boot so compression/encryption doesn''t have to be implemented in grub. I was thinking of adding this functionality to the userspace application btrfstune. The way I was thinking of doing this is when btrfstune +c is applied to a directory or file the directory(and all its contents) or file will always be compressed reguardless of how the filesystem is mounted. The opposite would happen when btrfstune -c is used. Would this be a reasonable thing to...

This needs to support older btrfs-progs versions though, so run btrfstune to check whether it has the -U parameter, and if not return the old error message. Something like test_btrfs_device_add_needs_force for example. Also: $ btrfs --version btrfs-progs v4.0 $ btrfstune --help btrfstune: invalid option -- '-' usage: btrfstune [options] device -S value...

Hi Seto, please could you update also the man page too ? Why it was not provided a way to clear a *single* flag ? To me it seems a bit too long to clear all the flag (btrfs mount-option clear) and then set the right one. As user interface I suggest something like chmod: btrfs mount-option set +ssd,skip_balance -nodatacow /dev/sdX or btrfs mount-option set =ssd,skip_balance,nodatacow
