Hi,

What happens when a DLE on a client goes to tape directly (PORT-WRITE)
because it can't fit in the holding disk and it bigger than tape
capacity? Is it possible to use tape spanning in that case?

One more: I have this DLE on a client using a tape-spanning dumptype
along with calcsize. Previously I was using excludes/includes but
yesterday I decided to have a go with spanning. I thought I'd fool
amanda by not forcing a full dump but then this situation happens:
calcsize reported a incremental of 32MB but that was way off as 11
chunks of 9GB were written to tape (8 on one tape and 3 others on the
next tape) then amanda reported 'dump to tape filed' and gave up.
Since that DLE is over 200GB and the holdingdisk use is 100GB I
suspect amanda gave because it thought that there was no more holdind
disk. amdump Right?

I can provide the entire amdump logfile and tape content is someone
is willing to enlighten me but here are the last lines before
quitting:
