Description
We saw this OSS LBUG yesterday following the use of lfs ladvise. Both 2.12.8 -based clients and servers (we have a few patches on top).
The command that triggered this from a client as root was:
touch testladvise lfs ladvise -a dontneed -s 0 -e 1048576000 testladvise
Result on the OSS:
Mar 24 18:53:55 oak-io7-s1 kernel: LustreError: 3782:0:(dt_object.h:2507:dt_ladvise()) ASSERTION( dt->do_body_ops->dbo_ladvise ) failed: Mar 24 18:53:55 oak-io7-s1 kernel: LustreError: 3782:0:(dt_object.h:2507:dt_ladvise()) LBUG Mar 24 18:53:55 oak-io7-s1 kernel: Pid: 3782, comm: ll_ost_io00_111 3.10.0-1160.6.1.el7_lustre.pl1.x86_64 #1 SMP Mon Dec 14 21:25:04 PST 2020 Mar 24 18:53:55 oak-io7-s1 kernel: Call Trace: Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffc085c7cc>] libcfs_call_trace+0x8c/0xc0 [libcfs] Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffc085c87c>] lbug_with_loc+0x4c/0xa0 [libcfs] Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffc15e12ce>] ofd_ladvise_hdl+0xdee/0xf10 [ofd] Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffc1235f1a>] tgt_request_handle+0xada/0x1570 [ptlrpc] Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffc11dabfb>] ptlrpc_server_handle_request+0x24b/0xab0 [ptlrpc] Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffc11de564>] ptlrpc_main+0xb34/0x1470 [ptlrpc] Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffac0c5c21>] kthread+0xd1/0xe0 Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffac794ddd>] ret_from_fork_nospec_begin+0x7/0x21 Mar 24 18:53:55 oak-io7-s1 kernel: [<ffffffffffffffff>] 0xffffffffffffffff
However, I can't seem to reproduce on a test system. It is not time sensitive for us. Just wanted to open a ticket as I didn't find this LBUG on the Jira.
