LVM Linux volume management

  • NOTE:201507: Rather look at btrfs, it is reasonably mature, and does most thins lvm is used for.

  • All Harddrives(HD's = pv=physicalvolumes) are put into a vg(volume group = 1big virtual hd) and then you partion it into lv's(logical volumes)
  • #Installing_Debian_with_SATA_based_RAID

Why ?

  • LV's can migrate while live - e.g. remove a disk
  • LV's can expand while live

Notes

vgchange -a n
vgscan --mknodes (may not be neccessary, but won't hurt)
vgexport -a
vgimport -a
vgchange -a y

That should bring them back to life.
