Bug 26842

Summary:	dump with h flag takes a very long time
Product:	Base System	Reporter:	Nick Sayer <nsayer>

Status:	Closed FIXED
Severity:	Affects Only Me

Description Nick Sayer 2001-04-25 17:50:01 UTC

The problem was noticed with the amanda port. Amanda does a

dump 0fhs /dev/null 0 1048576 /usr

and waits until the end of pass II to get an estimate of how much space
the real dump will take.

On this machine, with 4.3-RELEASE, the above command can take upwards of
a half hour to complete pass II.

dump 0fs /dev/null 1048576 /usr

completes pass II almost immediately.

Something about hierarchical dump flag processing has added
exponentially to the amount of time Pass II takes to complete.

Dima did work on inheriting nodump down hierarchy, maybe you could look at this?

I've been sitting on this too long, and it doesn't look like I'll have 
time to look at it very soon. Returning it to the regular bugs queue. 
Sorry.

Hi,

I can't recreate this on FreeBSD 6.x.  Can you confirm please if you
still see this problem?

Thanks,

Gavin
