I already know how to proceed when using XFS in the two scenarios tha= t follow: 1) XFS on EBS =46reeze XFS by using "xfs_freeze -f", then create EBS snapshot, then unfreeze XFS by using "xfs_freeze -u". 2) XFS on LVM XFS is automatically frozen/unfrozen when LVM snapshot is requested. What I don't know is how to proceed in the following scenarios: 3) Btrfs on EBS What commands need to be executed to freeze/unfreeze Btrfs when requesting EBS snapshot? 4) Btrfs on LVM Is Btrfs automatically frozen/unfrozen when requesting LVM snapshot? 5) LVM on EBS What command needs to be executed to freeze/unfreeze LVM? What about the FS on top of LVM? I know that scenario 5 is not Btrfs related, but I appreciate if someone could help me with that too. I also know that there is no need to use Btrfs on LVM, but the question remains. If there is any difference betweens kernel 2.6.21 and 2.6.35, please point it out.
