So I didn't go to sleep. The VG took /one and a half hours/ to activate.
And operations such as pvdisplay /dev/sdau1 take ages (minutes and
minutes), and the pvdisplay appears to hog cpu. Meanwhile:

[jmmpelto at pcn3 ~]$ sudo dd if=/dev/sdau1 of=/tmp/huu bs=1k count=10000
10000+0 records in
10000+0 records out
10240000 bytes (10 MB) copied, 0.30667 seconds, 33.4 MB/s

Er.
