How to share IBM Storage Archive on a Linux® system.
About this task
Beginning with version 2.1.2, IBM Storage Archive Library Edition for Linux allows users to share IBM Storage Archive by using the Network
File System (NFS). IBM Storage Archive Library Edition
for Linux is implemented with File system in
Userspace (FUSE), which is a kernel module that provides functions for a user
space program to be able to implement a fully functional file system.
File sharing by using NFS requires the -o noforget option when you mount a
library. For more information, see
ltfs.
Procedure
Complete the following steps to export an IBM Storage Archive medium by using NFS on
a Linux system.
- Stop the NFS server.
-
Configure the NFS server to export the IBM Storage Archive mount point.
-
Mount IBM Storage Archive to
the mount point as shown in the following example:
ltfs -o devname=/dev/sg10 -o noforget [mount point]
Notes:
- The opt option is required to resolve inode and file by using NFS.
- The sync time must not be close or many indexes are written. It is recommended that you use the
default setting of 5 minutes. For more information, see Sync operation.
- Start the
NFS server.
-
Mount the exported IBM Storage Archive mount point in the NFS
clients with the hard and intr options.
-
Access the exported IBM Storage Archive mount point from the
NFS client.
-
Unmount the exported IBM Storage Archive mount point from all
NFS clients.
- Stop the NFS server.
-
Unmount IBM Storage Archive.
Results
It is possible that requests from the NFS clients might be out of order. In this case,
IBM Storage Archive might return
an error if multiple operations are run against the same file in a short time, even if the requests
are serialized in the NFS clients.
