Hi,
I'm using Gluster 3.4.2 to manage qcow2 file used by some virtual machines.
I'm using Proxmox as virtualization system (3 node) with 2 gluster
external server (san1 and san2).
I'm storing the .qcow2 file (virtual image of virtual server) to gluster.
The .qcow2 are sparse file.
These the configuration of the volume:
# gluster volume info glusterb1
Volume Name: glusterb1
Type: Replicate
Volume ID: 76106c18-e7eb-4f02-bd86-cb90d41d8960
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: san1:/glusterfs2/glusterb1
Brick2: san2:/glusterfs2/glusterb1
These the mountpoint on my Proxmox (3 node):
san1:/glusterb1 on /mnt/pve/glusterb1 type fuse.glusterfs
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)
Everything seems to work correctly, but when I try to check the size
of the .qcow2 file on every gluster node, the dimensions do not match:
# ssh root at san1 du /glusterfs2/glusterb1/images/119 && ssh root at san2
du /glusterfs2/glusterb1/images/119
19124304 /glusterfs2/glusterb1/images/119
19124108 /glusterfs2/glusterb1/images/119
19124304 the file dimension on san1
19124108 the file dimension on san2
The volume are not in split-brain mode:
# gluster volume heal glusterb1 info split-brain
Gathering Heal info on volume glusterb1 has been successful
Brick san1:/glusterfs2/glusterb1
Number of entries: 0
Brick san2:/glusterfs2/glusterb1
Number of entries: 0
Is it possible that the two files on two nodes Gluster, have different
sizes ? or something is not working ?
sorry for my poor english
thank you very much
