Extended Volume Problem

[Jplanter]

Hello

I have an iSCSI target configured in my proxmox cluster and on the SAN I just recently extended the volume from 696GB to 1500GB however proxmox will not acknowledge the increase in size it still only detects the original 696GB of which I have nearly used up.

Thank in advance for your advice!

I think this will get you going... it's not as easy as in VMWare but not too bad. The link is for if you used the recommended LVM format.

Do you use a big iscsi lun with lvm on top ?
Do you use multipathing ?

Yes I use a big iscsi lun with lvm on top, not sure what multipathing is.

vgdisplay shows the vg I extended 'StoneFlySAS1VG':

  --- Volume group ---
  VG Name               StoneFlySAS1VG
  System ID             
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  1789
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                14
  Open LV               3
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               696.00 GiB
  PE Size               4.00 MiB
  Total PE              178175
  Alloc PE / Size       177673 / 694.04 GiB
  Free  PE / Size       502 / 1.96 GiB
  VG UUID               n0IKtN-ZJml-9rjQ-KJGL-xkHA-xCXg-2LhcQu

Notice the extended space "Free PE / Size 502 / 1.96 GiB". How do I get proxmox to recognize the change?

I have tried lvresize -L+905GB /dev/StoneFlySAS1VG but it says it needs a path for the volume group. Would I need to use vgextend??

Any help would be greatly appreciated!

Thank You!
