I'm trying to use btrfs quotas, but I'm unable to find reliable documentation on its usage. Let's start with an empty subvolume: - assign 200 MB space to it: # btrfs qgroup limit 200m /mnt/btrfs-backup/tester/ - see the usage: # btrfs qgroup show /mnt/btrfs-backup/tester/ 0/803 0 0 - let's add a 100 MB file: # dd if=/dev/urandom of=bigfile bs=1M count=100 - sync the FS to make sure quota is updated: # btrfs filesystem sync /mnt/btrfs-backup/ FSSync '/mnt/btrfs-backup/' - see current quota usage: # btrfs qgroup show /mnt/btrfs-backup/backuppc/tester/ 0/803 104882176 104882176 Now, my questions: - what do both 104882176 104882176 numbers represent? - how can I verify the quota assigned to any given subvolume? I've assigned 200 MB, but how can I verify that number? -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
