Na toto je LVM ( Logical Volume Manager ) Standardne je v SuSE Linuxe
uz v starsich verziach. Na konfigurovanie existuje aj graficke
rozhranie v YAST-e. (LVM pouziva HP-UX) Tymto sposobom mozes spojit
viacero IDE aj SCSI diskov do jednej VG (volume group) potom
nadefinujes LV (Logical Volume) vznikne ti /dev/vg00/lvol1 na tejto LV
vytvoris filesystem a namountujes ho tam kde potrebujes.
  Ja mam takto vytvoreny LV s 10 SCSI diksov a 1 IDE. Tu je vypis s
  pvscan:

rp:~ # pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/sda"  of VG "vg00" [492 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdb"  of VG "vg00" [492 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdc"  of VG "vg00" [312 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdd"  of VG "vg00" [304 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sde"  of VG "vg00" [1 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdf"  of VG "vg00" [312 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdg"  of VG "vg00" [312 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdh"  of VG "vg00" [304 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdi"  of VG "vg00" [304 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/sdj"  of VG "vg00" [304 MB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdc1" of VG "vg00" [808 MB / 0 free]
pvscan -- total: 11 [4.89 GB] / in use: 11 [4.89 GB] / in no VG: 0 [0]  

V uvedenom vypise je zrejme ze ide vsetko o stare disky s dnes uz
smiesnou kapacitou, ale toto funguje u mna asi 3 roky bez jedineho
problemu.

Ak by si chcel viac info ozvi sa mi mailom.
