Physical volumes / Partitions
Rescan scsi bus:
echo "- - -" >> /sys/class/scsi_host/host0/scan
Rescan a disk after resizing it:
echo 1 > /sys/block/sdb/device/rescan
Rescan a physical volume:
pvresize /dev/sdb
To manage a large disk (>2TB), use parted.
Logical volumes / filesystems
Resize jfs filesystem
lvresize --size +5G /dev/vg0/lv0
mount -o remount,resize /dev/vg0/lv0
Resize ext filesystem
lvresize --size +5G /dev/vg0/lv0
resize2fs /dev/vg0/lv0
