[linux-lvm] Problem activating lvm-raid

[Sven Eschenberg]

Hi all,

I recently had to reboot one of my machines which is usually up 24/7. To
my surprise the activation of the lvm-raid volume failed. I am kinda
stuck finding the reason - the userland got updated regularly and
everything used to work as expected.

Version of lvm being used: lvm2-2.02.181

lvchange -v -ay TsR1/port
Activating logical volume TsR1/port exclusively.
activation/volume_list configuration setting not defined: Checking
only host tags for TsR1/port.

dmsetup table:

TsR1-port_rimage_0: 0 8388608 linear 8:34 1024

Running lvchange again:
lvchange -v -ay TsR1/port
Activating logical volume TsR1/port exclusively.
Activation of logical volume TsR1/port is prohibited while logical
volume TsR1/port_rimage_0 is active.

Since activation fails, shouldn't the changes done not be rolled back
entirely? Usually one would expect identical behavior on a second
invocation.

And thje master question: Why does the activation fail in the first place?
