    Dear colleagues,

    [I'm under 4-STABLE]

    What is the correct sequence to delete existing vinum module (for example,
    raid10) and do *not* use -f flags for vinum?

    in my case t is raid10 vovume:

    vinum -> l -r t
    V t State: up Plexes: 2 Size: 8191 MB
    P t.p0 S State: up Subdisks: 2 Size: 8191 MB
    P t.p1 S State: up Subdisks: 2 Size: 8191 MB
    S t.d0 State: up PO: 0 B Size: 4095 MB
    S t.d8 State: up PO: 260 kB Size: 4095 MB
    S t.d2 State: up PO: 0 B Size: 4095 MB
    S t.d10 State: up PO: 260 kB Size: 4095 MB

    umount /dev/vinum/t
    vinum stop t (ok)
    vinum stop t.p0 <- this operation silently puts t up, and sets t.p0 faulty
    vinum stop t (ok)
    vinum stop t.p1

    Last comment leads to error

    Can't stop t.p1: Device busy (16)

    Final state of objects are

    vinum -> l -r t
    V t State: down Plexes: 2 Size: 8191 MB
    P t.p0 S State: faulty Subdisks: 2 Size: 8191 MB
    P t.p1 S State: up Subdisks: 2 Size: 8191 MB
    S t.d0 State: down PO: 0 B Size: 4095 MB
    S t.d8 State: down PO: 260 kB Size: 4095 MB
    S t.d2 State: up PO: 0 B Size: 4095 MB
    S t.d10 State: up PO: 260 kB Size: 4095 MB

    Any suggestions? should I dig into vinum sources to track this down?

    Thanks in advance.

    Sincerely,
    D.Marck [DM5020, MCK-RIPE, DM3-RIPN]
