Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 115)

the persistent image does not
show at all in the persistent
images list.
If this is a subsequent
persistent image, wait for
the NAS Manager to
complete a refresh or
press <F5>.
When I click Restore
Defaults on the Global
Settings page in Dell
ActiveArchive after taking a
persistent image, it changes
my cache file size and the area
is grayed out.
After you take a persistent image, you cannot change the
cache file size; therefore, clicking Restore Defaults does not
change the cache file size. To verify the cache file size, look at
the cache file size on the Volume Settings page. You should
see that it has reverted back to the original cache file size that
you set before taking a persistent image.
Take no action. Dell
ActiveArchive is functioning
as designed.
I get a permission error when
I try to access my persistent
images from an HTTP or FTP
share.
Accessing the persistent image directory through HTTP or FTP
is not supported.
If you need to access your
persistent image directory,
connect to the system
through a Terminal
Services Advanced Client
session and use Windows
Explorer in the NAS
system to access them.
When the maximum number
of persistent images (250 by
default) has been reached and
I continue to take more of
them, lower-priority persistent
images are overwriting the
existing higher-priority
persistent images.
If a persistent image is taken manually or by schedule,
ActiveArchive takes the persistent image even if the maximum
number of persistent images has been reached. Therefore, the
new persistent image must overwrite an existing persistent
image. By design, the new persistent image writes over the
oldest, lowest-priority persistent image available, even if it is a
higher-priority persistent image than the one currently being
taken.
Take no action.
ActiveArchive is functioning
as designed.
I noticed that the date and
time for the ActiveArchive
directory changes every time I
reboot my NAS system.
The ActiveArchive directory date and time are reset at each
reboot. The new dates and times do not change the dates and
times of your persistent images.
Take no action. This is the
normal functionality of
ActiveArchive.
I have deleted a persistent
image, but when the
Persistent Images page
redisplays I can still see the
persistent image. If I try to
delete it again, I get a blank
page.
In some environments, the Persistent Images page in the
NAS Manager refreshes too quickly.
Wait a few seconds and
refresh the page. You
should see that the
persistent image you
deleted is no longer listed.
When I try to take a
persistent image, a critical
error message states that the
snapshot could not be taken.
ActiveArchive may still be deleting or restoring a volume or
taking another snapshot.
Wait a few minutes for the
previous process to
complete and then try
again.
In the event log or on the
Status page, a message
states: An exception has
occurred. The data
contains the exception
record.
This is a known issue. Ignore this message. The
NAS system is functioning
normally.
After restoring a volume from
a persistent image, I cannot
mount to a share on that
volume from a Linux client.
During the restore, the volume is dismounted. From the NAS Manager,
restart NFS, and then
remount to a share on the
volume.
The % symbol does not show
in the ActiveArchive event
logs.
ActiveArchive event log messages that tell you how full the
cache file is and how close the system is to the maximum
allowed snapshots are generated messages. These messages
do not include the % symbol.
Take no action. The NAS
system is functioning as
designed.
