a pretty high load. Today I woke up and was terrified to see that database server is down. I could connect to it via SSH, but it was responding with bus error to each and every command: [root@r1304 home]# ls Bus error [root@r1304 home]# tail /var/log/messages Bus error [root@r1304 home]# reboot Bus error [root@r1304 home]# free -m Bus error [root@r1304 home]# chkdisk Bus error I went to Data Center and did a hard reset, which seemed to help, but after a half bus error linux command an hour situation reapeated and now I can't even connet via SSH anymore. Any ideas what this could be? how to diagnose such a problem and what are possible fixes? Server has 32 GB RAM, 2xSSD drives with software RAID UPDATE According to Zabbix, when MySQL died, number of processes stated to increase drammaticaly, until I did a hard reset. What could those be?

I'm bying a new one and restoring from a backup. –Temnovit Dec 10 '12 at 19:41 add a comment| 1 Answer 1 active oldest votes up vote 6 down vote accepted Your storage system seems to have failed. You can't read from disk at this point. Can you see the messages in the kernel ring buffer? Look at the output of dmesg if the command even works at this point. Do you have any backups or replication enabled? share|improve this answer answered Dec 8 '12 at 13:44 ewwhite 151k47300577 Thank you for your answer. Yes, I have cold backups and replication on another server.

That will typically cause a massive disaster. In general, you typically need to boot off another disk to rebuild root. And if you're using tar, this will imply that the tar archive needs to have been created with relative pathnames. Actually I would never attempt to recover root from a tar archive. I would reload the OS and then use the tar arcgive to grab a few files like /etc/paaswd and so on. I can't get more specific since I don't use SCO. I hope some SCO folks will jump in here with some more help.
