Hello, I have one server where i was installe oVirt node 4.1 and used in my infrastructure. It's used as single server cluster with local storage configured. I created separate volume for it and mounted as separate directory: [root@virt4 ~]# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert local_storage onn Vwi-aotz-- 350.00g pool00 7.27 ovirt-node-ng-4.1.0-0.20170201.0 onn Vri---tz-k 425.37g pool00 ovirt-node-ng-4.1.0-0.20170201.0+1 onn Vwi---tz-- 425.37g pool00 ovirt-node-ng-4.1.0-0.20170201.0 ovirt-node-ng-4.1.0-0.20170316.0 onn Vwi---tz-k 425.37g pool00 root ovirt-node-ng-4.1.0-0.20170316.0+1 onn Vwi---tz-- 425.37g pool00 ovirt-node-ng-4.1.0-0.20170316.0 ovirt-node-ng-4.1.1-0.20170322.0 onn Vri---tz-k 425.37g pool00 ovirt-node-ng-4.1.1-0.20170322.0+1 onn Vwi-aotz-- 425.37g pool00 ovirt-node-ng-4.1.1-0.20170322.0 2.17 pool00 onn twi-aotz-- 440.37g 18.44 9.91 root onn Vwi---tz-- 425.37g pool00 swap onn -wi-ao---- 7.88g var onn Vwi-aotz-- 15.00g pool00 16.28 mount: /dev/mapper/onn-local_storage on /local_storage type xfs (rw,relatime,seclabel,attr2,inode64,logbsize=256k,sunit=512,swidth=512,noquota) [root@virt4 ~]# ll / drwxr-xr-x. 3 vdsm kvm 76 Mar 23 09:02 local_storage All operations was done through cockpit UI With 4.1.1 upgrade i decided to upgrade it. After server reboot i discovered that my local storage folder was cleared, so i need to recreate all VMs and disks from scratch. Is this a bug or I did something wrong? Best regards, Misak Khachatryan
