Wie auf btrfs-cleaner warten?

[Uwe E. (Gast)]

Hi,
nachdem man mit

btrfs subvolume delete /..

ein größeres backup subvolume gelöscht hat, wie wartet man da auf den 
'btrfs-cleaner' bis er sein Job erledigt hat?


Danach soll der freigegeben Speicherplatz wieder mit einem neuen 
subvolume verwendet werden..

# btrfs subvolume delete --help

usage: btrfs subvolume delete [options] <subvolume> [<subvolume>...]

    Delete subvolume(s)

    Delete subvolumes from the filesystem. The corresponding directory
    is removed instantly but the data blocks are removed later.
    The deletion does not involve full commit by default due to
    performance reasons (as a consequence, the subvolume may appear again
    after a crash). Use one of the --commit options to wait until the
    operation is safely stored on the media.

    -c|--commit-after      wait for transaction commit at the end of the operation
    -C|--commit-each       wait for transaction commit after deleting each subvolume
    -v|--verbose           verbose output of operations
