<br>
I've got a strange problem with a gluster setup: 3 nodes with Centos 7.4, Gluster 3.12.4 from Centos/Gluster repositories, QEMU-KVM version 2.9.0 (compiled from RHEL sources).<br>
<br>
I'm running volumes in replica 3 arbiter 1 mode (but I've got a volume in "pure" replica 3 mode too). I've applied the "virt" group settings to my volumes since they host VM images.<br>
<br>
If I try to install something (eg: Ubuntu Server 16.04.3) on a VM (and so I generate a bit of I/O inside it) and configure KVM to access gluster volume directly (via libvirt), install fails after a while because the disk content is corrupted. If I inspect the block inside the disk (by accessing the image directly from outside) I can found many files filled with "^@".<br></blockquote></div></div></div></div></blockquote><div><br></div><div>Also, what exactly do you mean by accessing the image directly from outside? Was it from the brick directories directly? Was it from the mount point of the volume? Could you elaborate? Which files exactly did you check?<br></div><div><br></div><div>-Krutika</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
If, instead, I configure KVM to access VM images via a FUSE mount, everything seems to work correctly.<br>
<br>
Note that the problem with install is verified 100% time with QCOW2 image, while it appears only after with RAW disk images.<br>
<br>
Is there anyone who experienced the same problem ?<br>
<br>
Thank you,<span class="m_-4139169106555235646HOEnZb"><font color="#888888"><br>
