<div dir="ltr">Hi,<div><br></div><div>I'm using Proxmox for qemu hosts. I'm in situation, where I don't understand something :)</div><div>when I add gluster storage from Proxmox web GUI, I can install qemu guests without any caching. The mount -l shows me this output:</div>
<div><br></div><div><div>stor1:HA-MED-PVE1-1T on /mnt/pve/HA-MED-PVE1-1T type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)</div><div><br></div><div><br></div><div><br></div>
<div>But in this case, if 1 server is down (in case with HA brick), proxmox won't be able to read configuration from the 1st nor second server (Proxmox only knows about where it should failover for current running guests) and does not able to create new machines using this kind of mount.</div>
<div><br></div><div>If I add mount line like this in fstab:</div><div><div>stor1:HA-MED-PVE1-1T /mnt/pve/HA-MED-PVE1-1T glusterfs defaults,default_permissions,backupvolfile-server=stor2,direct-io-mode=enable,allow_other,max_read=131072 0 0</div>
</div><div><br></div><div>with mount -l now:</div><div><div>stor1:HA-MED-PVE1-1T on /mnt/pve/HA-MED-PVE1-1T type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)</div></div>
<div><br></div><div><br></div><div> I'm getting this error, when trying to start guests:</div><div><br></div><div><span style="color:rgb(0,0,0);font-family:tahoma,arial,verdana,sans-serif;font-size:11px;line-height:16px;white-space:pre">kvm: -drive file=/mnt/pve/HA-MED-PVE1-1T/images/125/vm-125-disk-1.qcow2,if=none,id=drive-virtio0,format=qcow2,aio=native,cache=none: file system may not support O_DIRECT</span><br>
</div><div>What could be the difference?</div>-- <br>Best regards,<br>Roman.</div></div>
