Hi, I experienced the same problems on two identical servers at the same time: Oct 5 01:06:01 server01 kernel: [472687.165519] md: data-check of RAID array md0 Oct 5 01:06:01 server01 kernel: [472687.165525] md: minimum _guaranteed_ speed: 1000 KB/sec/disk. Oct 5 01:06:01 server01 kernel: [472687.165528] md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for data-check. Oct 5 01:06:01 server01 kernel: [472687.165533] md: using 128k window, over a total of 48829440 blocks. Oct 5 01:06:01 server01 kernel: [472687.166340] md: delaying data-check of md1 until md0 has finished (they share one or more physical units) Oct 5 01:07:47 server01 syslogd 1.5.0#1ubuntu1: restart.
and: Oct 5 01:06:01 server02 kernel: [284514.605756] md: data-check of RAID array md0 Oct 5 01:06:01 server02 kernel: [284514.605761] md: minimum _guaranteed_ speed: 1000 KB/sec/disk. Oct 5 01:06:01 server02 kernel: [284514.605764] md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for data-check. Oct 5 01:06:01 server02 kernel: [284514.605769] md: using 128k window, over a total of 48829440 blocks. Oct 5 01:06:01 server02 kernel: [284514.606738] md: delaying data-check of md1 until md0 has finished (they share one or more physical units) Oct 5 01:07:34 server02 syslogd 1.5.0#1ubuntu1: restart. Both servers are Dell PowerEdge R200 with 4GB of RAM and 2x 400GB Sata disks. Both servers run DRBD (primary/primary) and OpenVZ. They had no load at this time. Kernel is: Linux serer01.XXXXXXXX 2.6.24-19-openvz #1 SMP Wed Aug 20 22:07:43 UTC 2008 x86_64 GNU/Linux. ** Attachment added: "lspci -vvnn" http://launchpadlibrarian.net/18287063/lspci-vvnn.log -- RAID1 data-checks cause CPU soft lockups https://bugs.launchpad.net/bugs/212684 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
