Hi there
I have a server, at a remote location, which has recently started to
intermittently fail backups.
The amanda client is running Debian Lenny, the amanda server is running
Debian Etch.
On the amanda server, dpkg -s amanda-server shows Version: 1:2.5.2p1-5
On the amanda client, dpkg -s amanda-client shows Version: 1:2.5.2p1-4
There are two firewalls between the two sites and both have the kernel
modules ip_nat_amanda and ip_conntrack_amanda loaded.
This is happening often enough to be a worry. I'd like to find out what
steps I can take.
I've replaced the actual name of the amanda client with <client.server> in
the enclosed log entries.
When it fails, in the daily email I get this error reported:
cannot read header: got 0 instead of 32768
On the client, in the sendbackup.20100106012630.debug log I see:
sendbackup-gnutar: time 0.056: /usr/lib/amanda/runtar: pid 3348
sendbackup: time 0.057: started backup
sendbackup: time 90.352: index tee cannot write [Broken pipe]
sendbackup: time 90.352: pid 3346 finish time Wed Jan 6 01:28:01 2010
On the server, in the amdump log I see:
driver: send-cmd time 1426.876 to taper: FILE-WRITE 00-00011
/dumps/amanda/holding/20100101003007/<client.server>._.1 <client.server>
UNKNOWNFEATURE / 1 20100101 0
driver: startaflush: LARGEST <client.server> / 1200164 353040132
(I see this UNKNOWNFEATURE on dle's that do finish fine).
I also see this on the server:
FAIL chunker <client.server> / 20100106 1 [cannot read header: got 0
instead of 32768]
Thanks

Please remember that an email is just like a postcard; it is not
confidential nor private nor secure and can be read by many other people
than the intended recipient. A postcard can be read by anyone at the mail
sorting office and expecting what is written on it to be private and secret
is not realistic. Please hold no higher expectation of email.
If you need to send confidential information in an email you need to use
encryption. PGP is Pretty good for this.
