While I touched on this in the second blog posting I made (Instantiating Savesets), it’s worthwhile revisiting this topic more directly.
Using ADV_FILE devices can play havoc with conventional tape rotation strategies; if you aren’t aware of these implications, it could cause operational challenges when it comes time to do recovery from tape. Let’s look at [...]
The scenario:
A clone or stage operation has aborted (or otherwise failed)
It has been restarted
It hangs waiting for a new volume even though there’s a partially written volume available.
This is a relatively easy problem to explain. Let’s first look at the log messages that happens. To generate this error, I started cloning some data to the [...]
Looking at the stats both for this new site and the previous site, I’ve compiled a list of the top 10 read articles on The NetWorker Blog for 2009. The top 3 of course match the three articles that routinely turn out to be the most popular on any given month, which speaks something of [...]
Something that continues to periodically come up is the need to remind people running manual staging to ensure they specify both the SSID and the Clone ID when they stage. I did some initial coverage of this when I first started the blog, but I wanted to revisit and demonstrate exactly why this is necessary.
The [...]
In NetWorker, staging refers to moving savesets from one piece of media to another. The move operation is two-fold, consisting of:
A clone operation (source -> target)
A delete operation (source)
Both of these operations are done automatically as part of the staging process, with the delete being defined as the maximum supported operation for the media that [...]
For the most part cloning and staging within NetWorker are pretty satisfactory, particularly when viewed from a combination of automated and manual operations. However, one thing that constantly drives me nuts is the inane reporting of status for cloning and staging.
Honestly, how hard can it be to design cloning and staging to accurately report the following [...]
Yesterday I wanted to delete a few savesets from a lab server I’d upgraded from 7.4.4 to 7.5.1.
Wanting to go about it quickly, I did the following:
I used “nsrmm -dy -S ssid” for each saveset ID I wanted to delete, to erase it from the media database.
I used “nsrstage -C -V volumeName” for the disk [...]
