Re: backup lasts forever on large fs
2003-11-11 14:52:40
Looks like the estimate has timed out after a 1/2 hour. I do not know why
estimation takes so long. What is more interesting: after amdump has
finished there is still a gtar process running:
load averages: 0.91, 0.90, 0.90
20:48:53
58 processes: 55 sleeping, 1 zombie, 2 on cpu
CPU states: % idle, % user, % kernel, % iowait, % swap
Memory: 2048M real, 1495M free, 104M swap in use, 5474M swap free
PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND
24118 root 1 20 0 49M 49M cpu/1 89:38 45.23% gtar
Here are the results of the test run:
