amdump freezes
2008-05-27 05:40:56
hello,
some clients with "big" partitions (>100Gbytes) freezes my amdump, I
usually get dumps errors which cannot end properly.
I have 2 questions,
1) how can I resolve that "client" error, timeout or whatever ?
2) why the amanda server doesnt giveup after dtimeout (1800s) and
finishes its amdump ?
I use amanda-2.5.0p2-4 on a centos 5.1 server with disk (virtual tapes
on a raid 5) backup media.
here's the client error:
