[Kernel-packages] [Bug 1898786] Re: bcache: Issues with large IO wait in bch_mca_scan() when shrinker is enabled
@mruffell, that's for Bionic, but for Focal is that still 5.4.0-56-generic? Or is there a new respun kernel to include these patches? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1898786 Title: bcache: Issues with large IO wait in bch_mca_scan() when shrinker is enabled Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: Fix Released Status in linux source package in Focal: Fix Released Bug description: BugLink: https://bugs.launchpad.net/bugs/1898786 [Impact] Systems that utilise bcache can experience extremely high IO wait times when under constant IO pressure. The IO wait times seem to stay at a consistent 1 second, and never drop as long as the bcache shrinker is enabled. If you disable the shrinker, then IO wait drops significantly to normal levels. We did some perf analysis, and it seems we spend a huge amount of time in bch_mca_scan(), likely waiting for the mutex ">bucket_lock". Looking at the recent commits in Bionic, we found the following commit merged in upstream 5.1-rc1 and backported to 4.15.0-87-generic through upstream stable: commit 9fcc34b1a6dd4b8e5337e2b6ef45e428897eca6b Author: Coly Li Date: Wed Nov 13 16:03:24 2019 +0800 Subject: bcache: at least try to shrink 1 node in bch_mca_scan() Link: https://github.com/torvalds/linux/commit/9fcc34b1a6dd4b8e5337e2b6ef45e428897eca6b It mentions in the description that: > If sc->nr_to_scan is smaller than c->btree_pages, after the above > calculation, variable 'nr' will be 0 and nothing will be shrunk. It is > frequeently observed that only 1 or 2 is set to sc->nr_to_scan and make > nr to be zero. Then bch_mca_scan() will do nothing more then acquiring > and releasing mutex c->bucket_lock. This seems to be what is going on here, but the above commit only addresses when nr is 0. From what I can see, the problems we are experiencing are when nr is 1 or 2, and again, we just waste time in bch_mca_scan() waiting on c->bucket_lock, only to release c->bucket_lock since the shrinker loop never executes since there is no work to do. [Fix] The following commits fix the problem, and all landed in 5.6-rc1: commit 125d98edd11464c8e0ec9eaaba7d682d0f832686 Author: Coly Li Date: Fri Jan 24 01:01:40 2020 +0800 Subject: bcache: remove member accessed from struct btree Link: https://github.com/torvalds/linux/commit/125d98edd11464c8e0ec9eaaba7d682d0f832686 commit d5c9c470b01177e4d90cdbf178b8c7f37f5b8795 Author: Coly Li Date: Fri Jan 24 01:01:41 2020 +0800 Subject: bcache: reap c->btree_cache_freeable from the tail in bch_mca_scan() Link: https://github.com/torvalds/linux/commit/d5c9c470b01177e4d90cdbf178b8c7f37f5b8795 commit e3de04469a49ee09c89e80bf821508df458ccee6 Author: Coly Li Date: Fri Jan 24 01:01:42 2020 +0800 Subject: bcache: reap from tail of c->btree_cache in bch_mca_scan() Link: https://github.com/torvalds/linux/commit/e3de04469a49ee09c89e80bf821508df458ccee6 The first commit is a dependency of the other two. The first commit removes a "recently accessed" marker, used to indicate if a particular cache has been used recently, and if it has been, not consider it for cache eviction. The commit mentions that under heavy IO, all caches will end up being recently accessed, and nothing will ever be shrunk. The second commit changes a previous design decision of skipping the first 3 caches to shrink, since it is a common case to call bch_mca_scan() with nr being 1, or 2, just like 0 was common in the very first commit I mentioned. This time, if we land on 1 or 2, the loop exits and nothing happens, and we waste time waiting on locks, just like the very first commit I mentioned. The fix is to try shrink caches from the tail of the list, and not the beginning. The third commit fixes a minor issue where we don't want to re-arrange the linked list c->btree_cache, which is what the second commit ended up doing, and instead, just shrink the cache at the end of the linked list, and not change the order. One minor backport / context adjustment was required in the first commit for Bionic, and the rest are all clean cherry picks to Bionic and Focal. [Testcase] This is kind of hard to test, since the problem shows up in production environments that are under constant IO pressure, with many different items entering and leaving the cache. The Launchpad git server is currently suffering this issue, and has been sitting at a constant IO wait of 1 second / slightly over 1 second which was causing slow response times, which was leading to build failures when git clones ended up timing out. We installed a test kernel, which is available in the following PPA: https://launchpad.net/~mruffell/+archive/ubuntu/sf294907-test Once the test

hang on rcs0
| [Fri Feb 14 18:55:37 2020] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
| [Fri Feb 14 18:55:37 2020] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
| [Fri Feb 14 18:55:37 2020] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
| [Fri Feb 14 18:55:37 2020] The GPU crash dump is required to analyze GPU
hangs, so please always attach it.
| [Fri Feb 14 18:55:37 2020] GPU crash dump saved to /sys/class/drm/card0/error
| [Fri Feb 14 18:55:37 2020] i915 :00:02.0: Resetting rcs0 for hang on rcs0

Maybe it's fixed in this commit which landed in Linux 4.6-rc2: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=596cf3fe5854fe2b1703b0466ed6bf9cfb83c91e -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1793753 Title: kernel panic - null pointer dereference on ipset operations Status in linux package in Ubuntu: Confirmed Bug description: Hi, We've experienced crashes on machines running iptables using ipsets. We could get a trace from the console on one of them (attached file kernel-trace.txt). On these machines, some ipset commands are automatically run to update the sets, and/or to dump them (ipset restore, swap, delete ... / ipset save). We strongly suspect the panic is happening due to a race when ipset updates happen at the same time as a dump. These machines are running xenial. Before the crash, they were on 4.4.0-116-generic #140-Ubuntu, but then rebooted into 4.4.0-135-generic #161-Ubuntu. I have an ipset save running in loops on one of these machines to try and reproduce quicker.

Bug #1579278 to consider switching to "performamce" may be of relevance here. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1584124 Title: revisit /etc/init.d/ondemand Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Triaged Bug description: We've been carrying /etc/init.d/ondemand for many years. We should revisit if booting with a kernel that defaults to "ondemand" right away is still actually slower than "performance". In the short term, systemd should grow a "Type=idle" unit that switches to ondemand, to replace the static "1 minute" sleep. This will also get rid of the last init.d script in "initscripts" that we actually use, and pave the way for dropping the initscripts package. In the long term, we could drop it completely if "ondemand" DTRT.

[Kernel-packages] [Bug 1579278] Re: Consider changing default CPU frequency scaling governor back to "performance" (Ubuntu Server)
Ah thanks. So maybe /etc/init.d/ondemand should have something to override or disable it (say DISABLE=1 in /etc/default/ondemand)? Looking at it currently, it seems to prefer governors in this order - interactive, ondemand, powersave. Even an option in /etc/default/ondemand to specify the preferred would be nice (e.g. PREFERRED_GOVERNOR=performance). ** Also affects: sysvinit (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1579278 Title: Consider changing default CPU frequency scaling governor back to "performance" (Ubuntu Server) Status in linux package in Ubuntu: Invalid Status in sysvinit package in Ubuntu: New Status in linux source package in Xenial: Invalid Status in sysvinit source package in Xenial: New Bug description: Hi, With the new Ubuntu archive servers, we saw constantly high load and after some tinkering, we found that it was mostly CPUs being woken up to see if they should enter idle states.

As Theodore Ts'o has pointed out[1]: """ ... with modern Intel processors, the ondemand CPU governor is actually counterproductive because waking up to decide whether the CPU is idle keeps it from entering the deepest sleep states, and so (somewhat counterintuitively) the performance governor will actually result in the best battery life.

Hi,
We're seeing this often on our HP Moonshot ARM64 nova-compute nodes
where qemu-nbd processes would lock up. At the same time, there's also
a bunch of kernel spew as follows:
