After configuring the SSDs for data storage as an NFS cache, ensure that the mount option
fsc
is set for all NFS-mounted file systems that you want to use the cache.
This example shows an entry in
/etc/fstab
for mounting a file system for which the
fsc
option is set.

4.7.7. Sanitizing the DGX Station Persistent Storage
Sanitizing the DGX Station persistent storage permanently destroys all the data that was
stored there. After the data is destroyed, it cannot be recovered. Sanitizing the DGX Station
persistent storage involves sanitizing
all
the SSDs for data storage
and
the SSD for the
operating system.
Deleting all files in the DGX Station persistent storage or reformatting all the DGX Station
SSDs does
not
sanitize the DGX Station persistent storage because data that was stored there
can still be recovered by data-recovery tools.
Before sanitizing the DGX Station persistent storage, prepare the following bootable
installation media:
‣
A bootable installation medium that contains the Ubuntu Desktop OS LiveCD
image. See
Preparing your LiveCD (https://help.ubuntu.com/community/
on the Ubuntu Community Help Wiki.
You'll need this installation medium to run an Ubuntu Desktop LiveCD session on the DGX
Station.
‣
A bootable installation medium that contains the current DGX OS Desktop image. See:
