[linux-lvm] Why LVM doesn't send the dm-thin delete message immediately after volume creation failure

[Ming-Hung Tsai]

Hi All,

I'm not sure if it is a bug or an intention. If there's error in
volume creation, the function _lv_create_an_lv() invokes lv_remove()
to delete the newly created volume. However, in the case of creating
thin volumes, it just queues a "delete" message without sending it
immediately. The pending message won't be process until the next
lvcreate.

Why not send it before the end of _lv_create_an_lv(), to ensure the
synchronization between LVM and kernel? (i.e., no dangling volume in
kernel metadata, and the transaction ID is also synced)


Thanks,
Ming-Hung Tsai
