Dear Nara,

 

All the partitions, pv and vg are created automatically during the initial setup time.

If we need any space we want to reduce the vg size and create new one.(This is correct)

 

 

If the above step is complicated, can you please suggest to setup glusterfs datastore in ovirt

yes, you can create. I do not see any problems there. 

 

May i know how these vgs are created ? If they are not created using gdeploy then you will have to create bricks manually from the new vg you have created.

Dear Nara,

 

Thank you for your great reply.

 

1) can you please check if the disks what would be used for brick creation does not have labels or any partitions on them ?

 

Yes I agreed there is no labels partition available, my doubt is it possible to create required bricks partition from available 406.7G  Linux LVM. Following are the physical volume and volume group information.

 

 

[root at ovirtnode1 ~]# pvdisplay 

  --- Physical volume ---

  PV Name               /dev/sda3

  VG Name               onn

  PV Size               555.73 GiB / not usable 2.00 MiB

  Allocatable           yes 

  PE Size               4.00 MiB

  Total PE              142267

  Free PE               3823

  Allocated PE          138444

  PV UUID               v1eGGf-r1he-3XZt-JUOM-8XiT-iGkf-0xClUe

   

[root at ovirtnode1 ~]# vgdisplay 

  --- Volume group ---

  VG Name               onn

  System ID             

  Format                lvm2

  Metadata Areas        1

  Metadata Sequence No  48

  VG Access             read/write

  VG Status             resizable

  MAX LV                0

  Cur LV                12

  Open LV               7

  Max PV                0

  Cur PV                1

  Act PV                1

  VG Size               555.73 GiB

  PE Size               4.00 MiB

  Total PE              142267

  Alloc PE / Size       138444 / 540.80 GiB

  Free  PE / Size       3823 / 14.93 GiB

  VG UUID               nFfNXN-DcJt-bX1Q-UQ2U-07J5-ceT3-ULFtcy

   

 

I am thinking, to reduce the vg size and create new vg for gluster. Is it a good thinking.

Hi,

 

   If i understand right gdeploy script is failing at [1]. There could be two possible reasons why that would fail.

 

1) can you please check if the disks what would be used for brick creation does not have lables or any partitions on them ?

 

2) can you please check if the path [1] exists. If it does not can you please change the path of the script in gdeploy.conf file to /usr/share/gdeploy/scripts/grafton-sanity-check.sh

 

[1] /usr/share/ansible/gdeploy/scripts/grafton-sanity-check.sh

 

Thanks

kasturi

Please note my finding.

 

1.    Still I am doubt with bricks setup ares . because during the ovirt node setup time automatically create partition and mount all space. Please find below #fdisk –l output

2.     

[root at ovirtnode4 ~]# fdisk –l

3.    Is it possible to create a LVM portions from 406.7G  Linux LVM free space for the required gluster size ?

 

Please suggest…..
