Warning: '/proc/partitions' does not match '/dev' directory structure.
    Name change: '/dev/scsi/host0/bus0/target0/lun0/disc' -> '/dev/sda'
    The kernel was compiled with DEVFS_FS, but 'devfs=mount' was omitted
        as a kernel command-line boot parameter; hence, the '/dev' directory
        structure does not reflect DEVFS_FS device names.
Added pld *
The Master boot record of  /dev/sda  has been updated.
Warning: /dev/sdb is not on the first disk
The Master boot record of  /dev/sdb  has been updated.

Dyski w macierzy hotswap, rok temu jak testowalem to wszystko
dzialalo - mozna bylo wyciagac ktorykolwiek dysk i wstawalo bez
problemow.
