Re: [Users] exception occured when adding NFS storage

Hi Sandro, I do see: # cat /etc/selinux/targeted/modules/active/file_contexts.local # This file is auto-generated by libsemanage # Do not edit directly. /mnt/iso(/.*)? system_u:object_r:public_content_rw_t:s0 /mnt/data(/.*)? system_u:object_r:public_content_rw_t:s0

# getenforce Permissive But I still failed to create a storage domain on the ovirt.engine side and got the same exception errors, and also vdsm is idle during the creation of storage domain. Here is the setup for ovirt.engine: oVirt Engine will be installed using the following configuration: ================================================================= override-httpd-config: yes http-port: 80 https-port: 443 host-fqdn: ovirt.engine auth-pass: ******** org-name: ovirt application-mode: both default-dc-type: NFS db-remote-install: local db-local-pass: ******** nfs-mp: /mnt/iso config-nfs: yes override-firewall: IPTables Proceed with the configuration listed above? (yes|no): yes Thanks, Hongyi From: Sandro Bonazzola [mailto:sbonazzo@redhat.com] Sent: Thursday, July 11, 2013 2:17 AM To: Zhang, Hongyi Cc: users(a)ovirt.org Subject: Re: [Users] exception occured when adding NFS storage Il 10/07/2013 18:19, Zhang, Hongyi ha scritto: Hi, I started to learn the oVirt by following the oVirt Quick Start Guide. I used one server as the ovirt.engine, and another server as the ovirt.host. Both servers run Fedora 18. After executing the command "engine-setup" in the ovirt.engine, I can get into the admin portal to start the configuration of host, storage, etc. Here was what I am doing: 1. In the Default data center, I clicked the Guide Me icon. The first thing is to configure the host. After waiting for 4-5 minutes, I saw the host ovirt.host is displayed under the Host tab with the Up status. 2. On the ovirt.engine server, I did the following before creating the storage: mkdir -p /mnt/data chown -R 36:36 /mnt/data Add the following line to /etc/sysconfig/nfs: NFS4_SUPPORT="no" Add the following line to /etc/exports: /nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36) systemctl restart nfs-server.service Well, exports has a typo error: /nmt/data instead of /mnt/data If that it's not enough, If you're using selinux ensure that /mnt/data has the correct context: /etc/selinux/targeted/modules/active/file_contexts.local: /mnt/data(/.*)? system_u:object_r:public_content_rw_t:s0 3. Back to the Default data center, clicked the Guide Me icon to start the configuration of new storage. 4. On the New Storage dialog, set Name field to be NFS-Share, and set the Export Path field to be ovirt.engine:/mnt/data. Then click OK After couple of minutes, I saw the error window popped up: Error: Cannot add Storage. Internal error, Storage Connection doesn't exist. From the /var/log/ ovirt-engine/engine.log, I can see: 2013-07-10 11:37:51,300 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ConnectStorageServerVDSComm and] (ajp--127.0.0.1-8702-1) [41c282da] FINISH, ConnectStorageServerVDSCommand, return: {00000000-0000-0000-0000-000000000000=100}, log id: 1bca7819 2013-07-10 11:37:51,303 ERROR [org.ovirt.engine.core.bll.storage.NFSStorageHelper] (ajp--127.0.0.1-8702-1) [41c282da] The connection with details 128.224.147.229:/mnt/data failed because of error code 100 and error message is: generalexception 2013-07-10 11:37:51,382 WARN [org.ovirt.engine.core.bll.storage.AddNFSStorageDomainCommand] (ajp--127.0.0.1-8702-6) [2612bf14] CanDoAction of action AddNFSStorageDomain failed.

Thanks, Hongyi P.S. If I create the NFS domain in the ovirt.host side (i.e., Export Path is ovirt.host:/mnt/data), then everything is okay. Not sure why failed on the ovirt.engine side. _______________________________________________ Users mailing list Users@ovirt.org<mailto:Users@ovirt.org> http://lists.ovirt.org/mailman/listinfo/users -- Sandro Bonazzola Better technology.
