Public bug reported: Binary package hint: linux-image-2.6.32-24-generic-pae
I upgraded from Ubuntu 8.04LTS to 10.04LTS last weekend, the system has been running fine untill today. For some reasons the webserver/mysql server stopped responding and I checked the console and noticed it being flooded by input/output errors. I managed to type dmesg and that was filled with this information as well. By now all services that had a reference to "/var/" (Which is mounted on /dev/md2, a raid5 set based on 4 disks) had stopped. After typing reboot the system came back up normally and mdadm started a resync of the raid5 set. No dataloss on the raid set detected. I immediately checked all the logs under /var/log and noticed they all stopped at the point the input/output errors started flooding the console. The errors that flooded the console did not end up in the dmesg logs probably because the /dev/md2 raidset was completely unavailable at the moment this occurred. The problem seems similar to the one I reported here: https://bugzilla.kernel.org/show_bug.cgi?id=11328#c48 This issue was NOT present under Ubuntu 8.04 with the 2.6.24 kernel, it was present under Debian Lenny with the 2.6.26 kernel. And unfortunately this bug seems to be present at the 2.6.32 kernel as well... The system has been running for about a year on 8.04LTS without any issues. System information: - Via Epia LT15000AG (Via CenterHaul Esther CPU, CX700 chipset), 1GB RAM - SiI3124 PCI-X sata controller - 2x Via Rhine II onboard NIC (VT6102) - 4x Samsung Spinpoint 160GB SATA hard drive connected to the SiI3124 controller. These drives are configured as follows: - /dev/md0 is a 4 disk RAID1 set containing the '/' filesystem. - /dev/md1 is a 4 disk RAID5 set used as swap. - /dev/md2 is a 4 disk RAID5 set used as the '/var/' filesystem. The system is running Ubuntu 10.04 LTS configured for only LTS packages and completely up to date (Except for the new kernel image that was ready for download this morning). I will attempt to create a photograph of the console if the error occurs again. Only thing I can get out of the dmesg log is the know bug that has been with the kernel since 2002 for the Via Rhine ethernet adapters. I've added a USB drive to the system and set up two sessions, one to tail the kernel log and one to tail dmesg. Both are dumping the output to a 512MB flash drive, this should be enough to capture the events preceding the issues. It is OK to consider this bug report incomplete until I managed to capture some logs. Attached lspci -vvv and dmesg output from the last boot. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- md raid5 set inaccessible after some time. https://bugs.launchpad.net/bugs/613872 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
