Hi all, have two questions: In sort: 1. Which sysctl's can/should I change to prevent my backupserver (7.0 BETA4) from rebooting by using rsync ? 2. What tools are there to find out what causes the reboot? I did not find any messages in /var/log/*, dmesg, vmstat and top (dmesg below). I assume that it runs out ouf buffers. Description: During a backup with rsync the backupserver (FreeBSD) reboots. Here I speak of homedirs wich have totaly ~200Gb. However I sync per homedir. Each homedirs has a quota from 500Mb to 8Gb. The storage server is (still) running linux. The backmachine has 680 Gb storage based on 3 (s)ata disk in raidz pool. The reboot mostly happens when accesing a maildirs of a users. On large files this problem occurs less often. The reboot is not at the same place /time while making the backup, but always after some (3-15 minutes) time. This is my a part of my backup script (on the storage machine): LIST=`ls /export/home` for DIR in $LIST do echo $DIR rsync -togplarv \ /export/home/${DIR} \ root_at_backup_server:/data/export/home/ done Some testing show that ZFS is not likely to cause this. test.sh (on the backupmachine): #!/bin/sh mkdir -p test C=0 ( cd test || exit while [ 1 ] do C=$(($C+1)) echo $C > file.${C} echo $C done ) will run fine up to > 120000 in a directory in zfs. I stopped testing after this. However rsyncing this test directory to my workstation will reboot the backup machine after a couple of minutes. I more details are nessecairy please let me know (dmesg below). kind regards, Marten %dmesg Copyright (c) 1992-2007 The FreeBSD Project.
