[Gluster-users] different size of file in replicated volume using sparse file
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
