Bug ID: 213915
Summary: [zfs] lots of CKSUM errors and sometimes even 'unkown
error 122'
Product: Base System
Version: 10.3-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-b...@freebsd.org
Reporter: k_georg...@deltanews.bg

FreeBSD VMWare virtual machine - zpool CKSUM counter keeps growing with over
10K errors per day. Sometimes get permanent damaged files with error 122.
Noticed on 3 systems with high I/O load so far. One of them is FreeBSD 10.1,
the other 2 are FreeBSD 10.3.
Issue is reproduced on both local and iSCSI storage. It also reproduces with
disk is attached via RDM (raw device mapping) and even it it's attached via
FreeBSD iscsid.
Not sure what causes it, because I have no clear log of ZFS CKSUM errors, but
it happens only on system with very high disk load. All underlying storage
devices I've tried to migrate the VMs on did not report any disk, or network
errors.
Investigation steps taken are described in this forum thread:
