Sometimes get permanent damaged files with error 122.=20 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.=20 Issue is reproduced on both local and iSCSI storage.

All underlying storage devices I've tried to migrate the VMs on did not report any disk, or network errors.=20 Investigation steps taken are described in this forum thread: https://forums.freebsd.org/threads/58282/ --=20 You are receiving this mail because: You are the assignee for the bug.=
