Subject: [Bug 198187] New: jbd2_log_wait_commit hangs
Date: Mon, 18 Dec 2017 12:56:48 +0000 [thread overview]
Message-ID: <bug-198187-13602@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=198187
Bug ID: 198187
Summary: jbd2_log_wait_commit hangs
Product: File System
Version: 2.5
Kernel Version: >=4.13
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: ext4
Assignee: fs_ext4@kernel-bugs.osdl.org
Reporter: lav@yar.ru
Regression: No
sometimes, a process stucks in jbd2_log_wait_commit wait state. After that, any
"sync" and probably fsync calls stuck too. The symptom is LA growing to insane
values. On one server the most common stuck process is logrotate in a lxc
container. I could not log in to two other affected servers. Another few
servers at my disposal do not exhibit this behaviour. There is no disk related
messages in the log or dmesg. Nothing suspicious at all in the log. Graceful
reboot hangs too.
The problem started with 4.13.8 and did not occur in 4.12.8.
Here is the dnf history info after which the problem started to occur:
Erase kernel-4.12.8-200.fc25.i686 @updates/25
Install kernel-4.13.8-100.fc25.i686 @updates/25
kernel downgrade fixes the problem.
