Hi folks,
Backing up a host as noted below im getting over and over again the same issue
on actual kernel, details:
- Backup host has a pci/usb2.0 card, with a 250gb usb 2.0 disk attached,
- Celeron 900 family
- Remote host, local console from boot linux rescue:
# dd if=/dev/hda conv=sync,noerror | ssh -c blowfish root(a)192.168.0.6 "dd
of=/media/backup/vol-hda.raw.img"
- Backup host (192.168.0.6), kernel bug from netdump - here spoolbox host- as
netdump-server:
[root@spoolbox /]# cat /var/crash/192.168.0.6-2006-07-27-10:46/log
