protoze budu disky presouvat na jine zelezo a nejspis navic jen jeden, potrebuju zrusit LVM na serveru, ktery jsem vytvoril. Nebo aspon jednu volumegroup a to bez ztraty dat, ale to se mi nedari, nebot mi hlasi, ze pro presun dat z jednoho disku na druhy neni misto, coz neni pravda. Ve volumegroup data jsou 2 fyzicke svazky, /dev/sd5 (620GB) a /dev/sdc1 (1TB). Pres df -h dostanu obsazene misto:

Filesystem                Size  Used Avail Use% Mounted on
/dev/mapper/data-seedbox  1.5T  837G  584G  59% /mnt/seedbox

Ovsem, pres pvscan, nebo pres pvs -o+pv_used dostanu uplne jina cisla.

root@kojiro:/home/bambas# pvscan
  PV /dev/sdb5   VG data     lvm2 [596.17 GiB / 0    free]
  PV /dev/sdc1   VG data     lvm2 [931.51 GiB / 7.68 GiB free]
  PV /dev/sda5   VG kojiro   lvm2 [55.66 GiB / 0    free]
  Total: 3 [1.55 TiB] / in use: 3 [1.55 TiB] / in no VG: 0 [0   ]

root@kojiro:/home/bambas# pvs -o+pv_used
  PV         VG     Fmt  Attr PSize   PFree Used
  /dev/sda5  kojiro lvm2 a--   55.66g    0   55.66g
  /dev/sdb5  data   lvm2 a--  596.17g    0  596.17g
  /dev/sdc1  data   lvm2 a--  931.51g 7.68g 923.83g

Z cehoz mne vyplyva, ze LVM si mysli, ze je volno je 7GB, ale to prece neni pravda i souborovy manazer mi vraci, ze mam volno 612GB). A diky tomu, ze si mysli, ze neni misto, nemuzu presunout data z jednoho pv na jiny:

root@kojiro:/home/bambas# pvmove /dev/sdb5 /dev/sdc1
  Insufficient free space: 152619 extents needed, but only 1966 available
  Unable to allocate mirror extents for pvmove0.
  Failed to convert pvmove LV to mirrored

Muzete mi prosim poradit, jak tedy Volume group "data" zrusit bez ztraty dat? Zkratka chci data presunout data na jeden fyzicky disk (/dev/sdc1) a ten pak pripojit v jinem stroji bez nutnosti vytvaret LVM a prenaset konfiguraci LVM... Diky. Zde jeste vypisy vg, pv lv:
