System information

Type Dell R730XD
Distribution Name CentOS Linux release
Distribution Version 7.5.1804
Linux Kernel 3.10.0-862.11.6
Architecture x86_64
ZFS Version 0.7.10.1
SPL Version 0.7.10.1

Describe the problem you're observing

Since the upgrade I now see thousands of attempt to access beyond the end of the partition in the kernel logs. Not happening on all systems running 0.7.10.1, only this one. Firmware updates also recently applied to this system. The data is still accessible, but a scrub causes the zpool to report as degraded.

Describe how to reproduce the problem

Upgrade zpool from 0.7.9.1 to 0.7.10.1.

Include any warning/errors/backtraces from the system logs

[ 1738.451499] attempt to access beyond end of device
[1738.451503] sdc1: rw=0, want=19396537888, limit=19396395008

# zpool status
  pool: data
 state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
        repaired.
  scan: scrub canceled on Thu Sep 13 12:20:20 2018

You will want to revert any systems which are observing this issue to 0.7.9. We'll be releasing an 0.7.11 tag as soon as possible which reverts the change which introduced this issue.

Between openzfs/zfs#7909,openzfs/zfs#7899, openzfs/zfs#7906 and http://list.zfsonlinux.org/pipermail/zfs-discuss/2018-September/032318.html, it seems like 0.7.10 should be clearly marked as "bad".
