https://bugzilla.kernel.org/show_bug.cgi?id=34302 --- Comment #2 from Tom Moore <tmoore@xxxxxxxxxx> 2011-05-03 16:27:25 --- Yes, it appears that there is additional in the syslog that is not in the messages file (sorry about that). May 3 01:02:25 fawkes kernel: [307200.700498] INFO: task kjournald:6416 blocked for more than 120 seconds. May 3 01:02:25 fawkes kernel: [307200.700506] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. The machine was doing a full backup of about 1Tb of data at the time using backuppc, so that might be the reason that the journal could not keep up. It is possible that something else in the crontab also kicked off at around that time. I am a bit confused by the messages however. The backup source is 2 SATA 3 (6Gbs) disks in a Raid-1 config; the backup target is 1 SATA2 (3gbs) disk. The final message of concern was May 3 01:40:09 fawkes kernel: [309464.781078] ata8.00: exception Emask 0x0 SAct 0x2 SErr 0x0 action 0x6 frozen May 3 01:40:09 fawkes kernel: [309464.781091] ata8.00: failed command: READ FPDMA QUEUED May 3 01:40:09 fawkes kernel: [309464.781107] ata8.00: cmd 60/08:08:47:0a:ab/00:00:45:00:00/40 tag 1 ncq 4096 in May 3 01:40:09 fawkes kernel: [309464.781111] res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) May 3 01:40:09 fawkes kernel: [309464.781118] ata8.00: status: { DRDY } May 3 01:40:09 fawkes kernel: [309464.781131] ata8: hard resetting link May 3 01:40:10 fawkes kernel: [309465.112103] ata8: SATA link up 6.0 Gbps (SStatus 133 SControl 300) May 3 01:40:10 fawkes kernel: [309465.119531] ata8.00: configured for UDMA/133 May 3 01:40:10 fawkes kernel: [309465.119543] ata8.00: device reported invalid CHS sector 0 May 3 01:40:10 fawkes kernel: [309465.119559] ata8: EH complete I am not 100% sure which disk ata8 corresponds to. I tried looking through the boot log to figure out the device assignments, but it was a bit confusing, It appears that ata8.00 is one of the source raid disks. If so, I wonder why it got reset? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
