how to make a cache directory nodatacow while also excluded from snapshots?
I want to exclude my ~/.cache directory from snapshots. The obvious way to do this is to mount a btrfs subvolume at that location. However, I also want the ~/.cache directory to be nodatacow. Since the parent volume is COW, I believe it isn't possible to mount the subvolume with different mount options. What's the solution for achieving both of these goals? I tried this without success: chattr +C ~/.cache Since ~/.cache is a btrfs subvolume, apparently that doesn't work. lsattr ~/.cache returns nothing. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
