| |
Dear maintainers,
I'm trying to get a machine running daily backups to its Maxtor 160GB disks for weeks now without success. The machine always hangs during the copy process. First try: kernel 2.5.23 on a Pentium-4 PC running debian linux 2.2 (potato). motherboard: GigaByte GA-8iRXP processor: P-4 1.6Ghz ram: 512 MB DDR-RAM disks: 6 Maxtor 160 GB (2 on the MB-IDE, 4 on the onboard Raid/ATA controller Promise 20276)
Second try: kernel 2.5.24, 2.5.25, 2.5.27
Thrird try: add separate IDE system disk (IBM Deskstar 80GB) -> it also locks up.
Usually I start the copying with crontab at mightnight. Lockup happens after 5-10 min., sometimes after a few hours, once or twice the machine ran for 2-3 days. But if I start the copying by hand, the freezing occurs as well.
I have the source files NFS mounted from the other linux and tru64 unix machines. Then I do: #! /bin/sh date /bin/cp -Rdp /juno/home /backup1/juno/ date /bin/cp -Rdp /juno/data1 /backup1/juno/ date /bin/cp -Rdp /juno/data2 /backup1/juno/ date
and so on. Usually just the first date appears in the log file. Nothing gets logged in /var/log/messages or kern.log.
Fourth try: remove all Maxtor disks and run only with the system disk -> freeze.
Fifth try: use another machine (AMD Dual processor 1900+ MP on a MSI K7D motherboard) with the system disk from the P4 system. kernel 2.5.25 and 2.5.27 lock up. *but* kernel 2.2.19pre17 runs ok. (although cannot be used with the large Maxtor disks, i.e. no support for disks bigger than 137GB, no 20276 suport).
I am at a loss what to do. It seems that all 2.5 kernels that I have tested have serious problems with IDE (at least in combination with NFS).
