Subject: assert failing with latency log
Date: Tue, 24 May 2016 17:40:10 -0400 (EDT) [thread overview]
Message-ID: <897324962.65623516.1464126010451.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <632274204.65621860.1464125206824.JavaMail.zimbra@redhat.com>
If I run this fio jobfile with absolute latest upstream code:
[global]
directory=/var/tmp
[randreads]
direct=1
rate_iops=1000
size=512m
ioengine=sync
bs=4k
rw=randread
filename=ben.dd
runtime=30
write_lat_log=foo
It fails with
fio: stat.c:1988: get_cur_log: Assertion `iolog->pending->nr_samples < iolog->pending->max_samples' failed.
But if I take out the "write_lat_log=foo" line, it succeeds. The assertion seems to be in the code path for latency logs, right? Anyone else seen this?
