Public bug reported: == Comment: #0 - Chanh H. Nguyen <chngu...@us.ibm.com> - 2016-09-08 15:01:30 == We have installed 16.04.1 on our guest and running IO stress test against via virtual qlogic disk. After running around 8 hrs, this error popping up "xfs_imap_to_bp: xfs_trans_read_buf() returned error -5" then with all of these errors "xfs_log_force: error -5 returned" fill up all the log.

Nguyen <chngu...@us.ibm.com> - 2016-09-08 15:02:27 == We recently re-created this bug on our new system "cressg2" which is using a different SAN on kernel -36. My Ubuntu 16.04.1 guest, cressg2, are running the IO and other stress test, and it is hitting "xfs_log_force: error -5 returned" problem after it runs the tests for 15 hours. It is using our lab storage (SVC SAN storage configuation with access to DS8000 Volume) and switch, compare to tinyg3, so it is using different storage and fabric switch. root@cressg2:~# uname -a Linux cressg2 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:00:57 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux [Wed Sep 7 10:26:48 2016] XFS (vdb8): xfs_log_force: error -5 returned.
