Hi Paul,

We were told by NetApp that they are working on a fix, but the bug hasn't even shown up in the NOW database yet... YMMV.

I believe this bug is reported as

17997 - dump fails to handle directory names with a null dos_name.

and is now online.

Cheers, Grant

We had this problem for a while, and we were told to upgrade to DoT 5.3.2D4, and Budtool 4.6.1. This stopped the pauses, but introduced a buffer overflow that makes the netapp dump core whenever it hits a "null DOS condition" while trying to back up. We aren't really sure what a "null DOS condition" is, but it makes us unhappy when we hit it. We were told by NetApp that they are working on a fix, but the bug hasn't even shown up in the NOW database yet... YMMV.

I thought I'd toss this one up for grabs, whilst I try to find support people to talk to.

I've got a BudTool 4.6, clustered F760, DOT 5.2.1 setup here, and I'm having the dickens of a time getting my filers backed up via NDMP.

Ordinarily I have file history turned on. It would appear that because of this, I'm ramming head on into NetApp BugID 9378. I do in fact see a large pause between pass III and pass IV. A 2 hour pause.

This is a problem, as 2 hours later, the backup dies with the following message in the logs:

Command exceeded maximum allowable run time 14400.

ie, 4 hours.

Questions I have:

• Has anybody found a way to circumvent the multiple-hour pause during a

BudTool NDMP backup, _while keeping file history on_ ?

• Anybody seen the `killing job after 4 hours' message? Anybody know a

workaround?

While highly sub-optimal, I have a backup running with no file history right now. I'm concerned that that 4 hour thing is gonna bite me in the butt again.

Suggestions? Comments? Shotgun shells to rid myself of this headache?
