Man möchte in einem LVM /dev/sdd1 durch /dev/sdc ersetzen.
Ohne viele Worte zu verlieren... so gehts:
root@imhotep:~ # pvcreate /dev/sdd
Physical volume "/dev/sdd" successfully created.
root@imhotep:~ # vgextend vg_media /dev/sdc
Volume group "vg_media" successfully extended
root@imhotep:~ # pvscan
PV /dev/sdd1 VG vg_media lvm2 [3,64 TiB / 0 free]
PV /dev/sde1 VG vg_media lvm2 [931,51 GiB / 0 free]
PV /dev/sdc VG vg_media lvm2 [3,64 TiB / 3,64 TiB free]
PV /dev/sdb VG vg_data lvm2 [3,64 TiB / 0 free]
Total: 4 [11,83 TiB] / in use: 4 [11,83 TiB] / in no VG: 0 [0 ]
Nun die Daten verschieben:
root@imhotep:~ # pvmove /dev/sdd1
/dev/sdd1: Moved: 0.0%
/dev/sdd1: Moved: 2.3%
/dev/sdd1: Moved: 3.8%
[... usw. ...]
/dev/sdd1: Moved: 98.8%
/dev/sdd1: Moved: 100.0%
Jezze können wir den alten Datenträger aus dem LVM herauskonfigurieren:
root@imhotep:~ # vgreduce vg_media /dev/sdd1
Removed "/dev/sdd1" from volume group "vg_media"
root@imhotep:~ # pvremove /dev/sdd1
Labels on physical volume "/dev/sdd1" successfully wiped
