Hi Paul & all, I found your other mail more convincing, the permission change might be just a side effect...
a) we think in 3.4.0 it was working, and we didn't changed the libvirt/qemu version (later in the day I will roll back to gluster from raring (13.04) repo and try to reproduce, just to be sure) b) If it would be just a libvirt issue, why is the file not accesible even for root on the host OS? root@pong[/3]:~ # file /srv/vms/mnt_atom01/atom01.img /srv/vms/mnt_atom01/atom01.img: writable, regular file, no read permission while it is readable on the brick root@pong[/3]:~ # file /ecopool/fs_atom01/atom01.img /ecopool/fs_atom01/atom01.img: x86 boot sector; partition 1: ID=0x83, starthead 1, startsector 63, 16777165 sectors; partition 2: ID=0xf, starthead 254, startsector 16777228, 1677718 sectors, code offset 0x63 in this case host "pong" is the receiving side of the migration, on host "ping", the file stays readable root@ping[/1]:~ # file /srv/vms/mnt_atom01/atom01.img /srv/vms/mnt_atom01/atom01.img: x86 boot sector; partition 1: ID=0x83, starthead 1, startsector 63, 16777165 sectors; partition 2: ID=0xf, starthead 254, startsector 16777228, 1677718 sectors, code offset 0x63 Regards Bernhard On 28.01.2014 13:57:48, Paul Boven wrote: > Hi everyone, > > On the libvirt Wiki, I found the text below which might well apply to > our live-migration issue: > > "The directory used for storing disk images has to be mounted from > shared storage on both hosts.
