I fixed the problem of the "high server load" by installing amanda
version 2.4.4p1 on the server and the clients.
amcheck daily now reports:
Amanda Tape Server Host Check
-----------------------------
Holding disk /big/backup/amanda/dumps: 1034688 KB disk space available,
using 215488 KB
ERROR: /dev/nst0: rewinding tape: Input/output error
(expecting tape DailySet1-003 or a new tape)
NOTE: skipping tape-writable test
Server check took 30.099 seconds
Amanda Backup Client Hosts Check
--------------------------------
Client check: 3 hosts checked in 1.076 seconds, 0 problems found
(brought to you by Amanda 2.4.4p1)
But the backups fail. Checking the logs in /tmp/amanda (on the
clients), I see things like:
sendbackup: time 0.000: stream_server: waiting for connection: 0.0.0.0.33011
sendbackup: time 0.001: stream_server: waiting for connection: 0.0.0.0.33012
sendbackup: time 0.001: stream_server: waiting for connection: 0.0.0.0.33013
sendbackup: time 0.001: waiting for connect on 33011, then 33012, then 33013
sendbackup: time 29.991: stream_accept: timeout after 30 seconds
sendbackup: time 29.991: timeout on data port 33011
sendbackup: time 59.991: stream_accept: timeout after 30 seconds
sendbackup: time 59.991: timeout on mesg port 33012
sendbackup: time 89.991: stream_accept: timeout after 30 seconds
sendbackup: time 89.991: timeout on index port 33013
sendbackup: time 89.991: pid 1873 finish time Thu Jan 8 01:05:15 2004
All hosts were configured with:
--with-tcpportrange=850,854 --with-udpportrange=850,854
So why am I getting connections on port 33011? I have 850-854 opened on
the firewall, but if it's trying to connect on 33xxx then of course it's
not going to work.
On the server, my /etc/services has:
amanda 850/udp # amanda backup services
amanda 850/tcp
kamanda 851/tcp # amanda backup services
(Kerberos)
kamanda 851/udp # amanda backup services
(Kerberos)
amandaidx 852/tcp # amanda backup services
amidxtape 853/tcp # amanda backup services
The clients have:
amanda 850/udp
amanda 850/tcp
kamanda 851/udp
amandaidx 852/tcp
