Hi,
CS 4.17.2.0 XCP-ng 8.2.1 I run into a problem regarding secondary storage and XCP-ng. After the second time I do some action which involves secondary storage, like doing a volume-snapshot, I get an error: [error||8537 ||backtrace] Raised Server_error(XENAPI_PLUGIN_FAILURE, [ mountNfsSecondaryStorage; SROSError; Error reporting error, unknown key Unexpected error while trying to mount 10.10.1.3:/storage/secondary/ to /var/cloud_mount/37ca744e-63ee-3ef0-a95b-20e6c729fbbd ]) I can see the following in in XCP-ng SMlog: FAILED in util.pread: (rc 32) stdout: '', stderr: 'mount.nfs: /var/cloud_mount/37ca744e-63ee-3ef0-a95b-20e6c729fbbd is busy or already mounted Which is correct. The secondary storage is already been mounted. After some investigation I found the following issues in github: https://github.com/apache/cloudstack/issues/6199 https://github.com/apache/cloudstack/pull/5886 I fixed the problem with changing global setting secstorage.nfs.version to 3. I am able to reproduce this issue by changing it to 4, 4.1 or delete the entry. As far as I understand nobody can use XCP-ng without setting this global setting to 3. Did somebody else run into that and is able to reproduce it? Cu Swen
