[SOLVED] Duplicate LVM volume group causing issue.

[RobFantini]

/etc/lvm/archive had over 100,000 files on each node.

I think the issue is due to duplicate volume group 'turnkey' :

# pvs
  PV  VG  Fmt  Attr PSize  PFree  
  /dev/sdac  lxc-on-omnios-vg lvm2 a--  300.00g 290.00g
  /dev/sdj5  turnkey  lvm2 a--  6.76g 696.00m
  /dev/sdr5  turnkey  lvm2 a--  3.76g 392.00m

to me that is like a network having 2 devices with the same IP.

can some suggest a way to track down if either lvm group is in use?


more info on the 100,000

ls -ld /etc/lvm/archive/
drwx------ 2 root root 105504 Apr 23 17:46 /etc/lvm/archive/

I'm going to delete them. may by a side affect of a bad iscsi setup on my part earlier in the week.
here is a partial list:

I've got to delete not, no time now to try to debug how this happened.

after deleting they are coming back fast.

so for now I disabled lvm archive in lvm.conf

some lvm commands:

# vgs
  VG  #PV #LV #SN Attr  VSize  VFree 
  lxc-on-omnios-vg  1  1  0 wz--n- 300.00g 290.00g
  turnkey  1  2  0 wz--n-  6.76g 696.00m
  turnkey  1  2  0 wz--n-  3.76g 392.00m

# pvs
  PV  VG  Fmt  Attr PSize  PFree  
  /dev/sdac  lxc-on-omnios-vg lvm2 a--  300.00g 290.00g
  /dev/sdj5  turnkey  lvm2 a--  6.76g 696.00m
  /dev/sdr5  turnkey  lvm2 a--  3.76g 392.00m

# lvs
  LV  VG  Attr  LSize  Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  vm-3039-disk-1 lxc-on-omnios-vg -wi-------  10.00g   
  root  turnkey  -wi-------  5.08g   
  root  turnkey  -wi-------  2.38g   
  swap_1  turnkey  -wi------- 1020.00m   
  swap_1  turnkey  -wi------- 1020.00m

I'll track down why there are two volume groups named turnkey tomorrow.

solved by removing lxc on iscsi . I am not sure what caused the issue. notes on how lxc on iscsi were set up are at wiki. there may have been something wrong with my set up or a bug or both.
