NFS Shares Folder issue

[apmuthu]

When we create an NFS Share (Storage) we are forced to do a Scan after providing the IP and then the Export path gets filled in - no option to enable us to choose a folder on that path.

If we choose to store Content as Virtual Disks, then an images folder (within the NFS Share) is created or chosen to store the Virtual Disks.

If we choose to store Content as VZDump Backups, then it is stored directly in the NFS Share itself and not in a preferred backups folder within it. The same is the case if the Content is chosen to be ISO Images.

Workaround is to
1. create the NFS Share for the Virtual Disks
2. create a backups folder in the NFS Share
3. create a Storage -> Directory -> use the path of the backups folder - /mnt/NFSShareName/backups
4. Use the Directory Storage for the Backups

What is the purpose of the Share checkbox for the Directory Storage?

What is the purpose of the Share checkbox for the Directory Storage?

e.g. if you mount a OCFS2 filesystem you can mark it as shared.

Thanks Tom. Read the OCSF2 User Guide - Circa 2008. Nice intro.

Shared disk clustered file systems come in two flavors: asymmetric and symmetric. Asymmetric refers to file systems that allow each server node to read/write data directly to the SAN, but direct all the meta-data change operations to a single node. Symmetric, on the other hand, allows each node to read and write both meta-data and data directly to the SAN.

OCFS2 is a symmetric shared disk cluster file system.
