Package: src:linux Version: 3.16.7-ckt11-1 Severity: normal Tags: patch upstream
Dear Maintainer, * What led up to the situation? Running as an Hyper-V guest, I see sporadic messages like the ones you can see at the end of this dmesg output. This doesn't appear to be related to what happens on the machine, it may be related to the underlying storage taking backup snapshots, but I am not sure since I don't have access to it. In one occasione dmesg said: [1710593.904046] sd 2:0:0:0: Warning! Received an indication that the operating parameters on this target have changed. The Linux SCSI layer does not automatically adjust these parameters. [1710593.904061] end_request: I/O error, dev sda, sector 531976632 [1710593.905535] Aborting journal on device sda5-8. [1710593.912586] EXT4-fs error (device sda5): ext4_journal_check_start:56: Detected aborted journal [1710593.913975] EXT4-fs (sda5): Remounting filesystem read-only [1797034.976074] EXT4-fs (sda5): error count since last fsck: 2 [1797034.976116] EXT4-fs (sda5): initial error at time 1436081211: ext4_journal_check_start:56 [1797034.976133] EXT4-fs (sda5): last error at time 1436081211: ext4_journal_check_start:56 The FS was read-only, we had to reboot and manually run fsck. This appears to be the bug in the Hyper-V virtualized storage driver described in: https://social.technet.microsoft.com/Forums/windowsserver/en-US/8807f61c-565e-45bc-abc4-af09abf59de2/ubuntu-14042-lts-generation-2-scsi-errors-on-vss-based-backups That bug lead to the patch: http://git.kernel.org/cgit/linux/kernel/git/jejb/scsi.git/commit/?id=dc45708ca9988656d706940df5fd102672c5de92 * What exactly did you do (or not do) that was effective (or ineffective)? Most of this messages are harmless, when it remounted RO we rebooted. * What was the outcome of this action? fsck had to be run manually * What outcome did you expect instead? I expect the FS not to be remounted read-only. -- Package-specific info: ** Version: Linux version 3.16.0-4-amd64 ([email protected]) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) ** Command line: BOOT_IMAGE=/boot/vmlinuz-3.16.0-4-amd64 root=UUID=c52e963f-ad44-49b5-b657-65ffae35a135 ro quiet ** Not tainted ** Kernel log: [ 1.307341] cdrom: Uniform CD-ROM driver Revision: 3.20 [ 1.307713] sr 1:0:0:0: Attached scsi CD-ROM sr0 [ 1.310584] sd 2:0:0:0: Attached scsi generic sg0 type 0 [ 1.310821] sr 1:0:0:0: Attached scsi generic sg1 type 5 [ 1.800087] tsc: Refined TSC clocksource calibration: 1999.998 MHz [ 2.013645] hv_netvsc vmbus_0_13: Send section size: 6144, Section count:170 [ 2.013955] hv_netvsc vmbus_0_13: Device MAC 00:15:5d:00:87:1f link state up [ 2.273864] PM: Starting manual resume from disk [ 2.273873] PM: Hibernation image partition 8:1 present [ 2.273875] PM: Looking for hibernation image.
