Hello, oVirt Engine Version: 3.5.0.1-1.el6 We recently removed the Data (Master) storage domain from our ovirt cluster and replaced it with another. All is working great. When looking at the old storage device I noticed that one of our nodes still has an NFS connection to it. Looking at the results for 'mount' I see two mounts to the node in question (192.168.64.15): 192.168.64.15:/nfs-share/ovirt-store/hosted-engine on /rhev/data-center/mnt/192.168.64.15:_nfs-share_ovirt-store_hosted-engine type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.15,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.64.15) 192.168.64.11:/export/testovirt on /rhev/data-center/mnt/192.168.64.11:_export_testovirt type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.11,mountvers=3,mountport=46034,mountproto=udp,local_lock=none,addr=192.168.64.11) 192.168.64.163:/export/storage on /rhev/data-center/mnt/192.168.64.163:_export_storage type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.163,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.64.163) 192.168.64.55:/export/storage on /rhev/data-center/mnt/192.168.64.55:_export_storage type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.55,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.64.55) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,relatime) 192.168.64.15:/nfs-share/ovirt-store/hosted-engine on /rhev/data-center/mnt/192.168.64.15:_nfs-share_ovirt-store_hosted-engine type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.15,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.64.15) 10.1.90.64:/ifs/telvue/infrastructure/iso on /rhev/data-center/mnt/10.1.90.64:_ifs_telvue_infrastructure_iso type nfs (rw,relatime,vers=3,rsize=131072,wsize=524288,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=10.1.90.64,mountvers=3,mountport=300,mountproto=udp,local_lock=none,addr=10.1.90.64) 192.168.64.163:/export/storage/iso-store on /rhev/data-center/mnt/192.168.64.163:_export_storage_iso-store type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=192.168.64.163,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=192.168.64.163) /etc/fstab has no entry for these so I assume they are left over from when the storage domain existed. Is it safe to 'umount' these mounts or is there a hook I may not be aware of? Is there another way of removing this from the node via that OVM? None of the other nodes in the cluster have this mount. This node is not the SPM. Thank you for your time and consideration.
