Mounting from KVM hosts to secondary storage seems to fail, every time a new VM instance is created, it will use up the / (root) partition of the KVM hosts instead. Here is the df result: ==== root@hv-kvm-02:/home/indra# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 4195924 4195924 0 100% / udev 132053356 4 132053352 1% /dev tmpfs 52825052 440 52824612 1% /run none 5120 0 5120 0% /run/lock none 132062620 0 132062620 0% /run/shm cgroup 132062620 0 132062620 0% /sys/fs/cgroup /dev/sda6 10650544 2500424 7609092 25% /home 10.237.11.31:/mnt/vol1/sec-storage2/template/tmpl/2/288 4195924 4195924 0 100% /mnt/5230667e-9c58-3ff6-983c-5fc2a72df669 ==== The strange thing is that df shows that it seems to be mounted, but it's actually not mounted. If you noticed, the total capacity of the mount point is exactly the same as the capacity of the / (root) partition. By right it should show 7 TB instead of just 4 GB. This caused VM creation to be error due to out of disk space. This also affect the KVM operations since the / (root) partition becomes full, and we can only release the space after we reboot the KVM host. Anyone experience this problem before? We are at loss on how to resolve the problem. Looking forward to your reply, thank you. Cheers. --e89a8ff1c4eee7b91204e7d82fa2--
