Vinum Spielereien

Hallo,

ich hab mich mal wieder dazu "aufgerafft" um mit Vinum zu spielen.
4 1GB Platten, RAID-5

root(at)nudel olivleh1> vinum l
6 drives:
D d1 State: up /dev/da1s1d A: 0/2008 MB (0%)

6 subdisks:

S lvmr1.p0.s0 State: up D: d1 Size: 2007 MB
S lvmr1.p1.s0 State: up D: d2 Size: 2007 MB

Von d6 den Stromstecker rausgezogen (Ich weiss, ich weiss -
Stromschwankungen sind nicht toll. Die anderen Drives waren
aber still. Und ich kann einen Plattenausfall auch nicht
anders simulieren)

(da6:sym0:0:3:0): Synchronize cache failed, status == 0x4a, scsi status == 0x0
(da6:sym0:0:3:0): removing device entry
GEOM: destroy disk da6 dp=0xc2df8450

Nach dem rausziehen, und einem ls auf den Mountpoint:

Die selbe Platte dann wieder rangehangen, ein camcontrol rescan.

root(at)nudel olivleh1> camcontrol rescan 1
Re-scan of bus 1 was successful
root(at)nudel olivleh1> camcontrol devlist -v

root(at)nudel olivleh1> vinum start lvmr5.p0.s3
Can't start lvmr5.p0.s3: Drive is down (5)

Was nun?

root(at)nudel olivleh1> vinum stop
Can't unload vinum: No such file or directory
root(at)nudel olivleh1> vinum start

Und nun haengt es... wie auch mein ls... Sorry, aber kann man sowas
ueberhaupt semi-produktiv einsetzen? Ist ein FreeBSD 5.2-REL

   Gruesse, Oliver
