Provide more documentation for MDS performance tuning on large file systems

by Janek Bevendorff

Hello, Over the last week I have tried optimising the performance of our MDS nodes for the large amount of files and concurrent clients we have. It turns out that despite various stability fixes in recent releases, the default configuration still doesn't appear to be optimal for keeping the cache size under control and avoid intermittent I/O blocks. Unfortunately, it is very hard to tweak the configuration to something that works, because the tuning parameters needed are largely undocumented or only described in very technical terms in the source code making them quite unapproachable for administrators not familiar with all the CephFS internals. I would therefore like to ask if it were possible to document the "advanced" MDS settings more clearly as to what they do and in what direction they have to be tuned for more or less aggressive cap recall, for instance (sometimes it is not clear if a threshold is a min or a max threshold). I am am in the very (un)fortunate situation to have folders with a several 100K direct sub folders or files (and one extreme case with almost 7 million dentries), which is a pretty good benchmark for measuring cap growth while performing operations on them. For the time being, I came up with this configuration, which seems to work for me, but is still far from optimal: mds basic mds_cache_memory_limit 10737418240 mds advanced mds_cache_trim_threshold 131072 mds advanced mds_max_caps_per_client 500000 mds advanced mds_recall_max_caps 17408 mds advanced mds_recall_max_decay_rate 2.000000 The parameters I am least sure about---because I understand the least how they actually work---are mds_cache_trim_threshold and mds_recall_max_decay_rate. Despite reading the description in src/common/options.cc, I understand only half of what they're doing and I am also not quite sure in which direction to tune them for optimal results. Another point where I am struggling is the correct configuration of mds_recall_max_caps. The default of 5K doesn't work too well for me, but values above 20K also don't seem to be a good choice. While high values result in fewer blocked ops and better performance without destabilising the MDS, they also lead to slow but unbounded cache growth, which seems counter-intuitive. 17K was the maximum I could go. Higher values work for most use cases, but when listing very large folders with millions of dentries, the MDS cache size slowly starts to exceed the limit after a few hours, since the MDSs are failing to keep clients below mds_max_caps_per_client despite not showing any "failing to respond to cache pressure" warnings. With the configuration above, I do not have cache size issues any more, but it comes at the cost of performance and slow/blocked ops. A few hints as to how I could optimise my settings for better client performance would be much appreciated and so would be additional documentation for all the "advanced" MDS settings. Thanks a lot Janek

atime with cephfs

by Oliver Freyermuth

Dear Cephers, we are currently mounting CephFS with relatime, using the FUSE client (version 13.2.6): ceph-fuse on /cephfs type fuse.ceph-fuse (rw,relatime,user_id=0,group_id=0,allow_other) For the first time, I wanted to use atime to identify old unused data. My expectation with "relatime" was that the access time stamp would be updated less often, for example, only if the last file access was >24 hours ago. However, that does not seem to be the case: ---------------------------------------------- $ stat /cephfs/grid/atlas/atlaslocalgroupdisk/rucio/group/phys-higgs/ed/cb/group.phys-higgs.17620861._000004.HSM_common.root ... Access: 2019-04-10 15:50:04.975959159 +0200 Modify: 2019-04-10 15:50:05.651613843 +0200 Change: 2019-04-10 15:50:06.141006962 +0200 ... $ cat /cephfs/grid/atlas/atlaslocalgroupdisk/rucio/group/phys-higgs/ed/cb/group.phys-higgs.17620861._000004.HSM_common.root > /dev/null $ sync $ stat /cephfs/grid/atlas/atlaslocalgroupdisk/rucio/group/phys-higgs/ed/cb/group.phys-higgs.17620861._000004.HSM_common.root ... Access: 2019-04-10 15:50:04.975959159 +0200 Modify: 2019-04-10 15:50:05.651613843 +0200 Change: 2019-04-10 15:50:06.141006962 +0200 ... ---------------------------------------------- I also tried this via an nfs-ganesha mount, and via a ceph-fuse mount with admin caps, but atime never changes. Is atime really never updated with CephFS, or is this configurable? Something as coarse as "update at maximum once per day only" would be perfectly fine for the use case. Cheers, Oliver

Nautilus: rbd image stuck unaccessible after VM restart

by islepnev＠gmail.com

Hello, I’m running kvm virtualization with rbd storage, some images on rbd pool become efficiently unusable after VM restart. All I/O to problematic rbd image blocks infinitely. Checked that it is not a permission or locking problem. The bug was silent until we performed a planned restart of few VMs and some of VMs failed to start (kvm process timed out). It could be related to recent upgrades luminous to nautilus or proxmox 5 to 6. Ceph backend is clean, no observable problems, all mons/mgrs/osds up and running. Network is ok. Nothing in logs relevant to the problem. ceph version 14.2.6 (ba51347bdbe28c7c0e2e9172fa2983111137bb60) nautilus (stable) kernel 5.3.13-2-pve #1 SMP PVE 5.3.13-2 (Fri, 24 Jan 2020 09:49:36 +0100) x86_64 GNU/Linux HEALTH_OK No locks: # rbd status rbd-technet/vm-402-disk-0 Watchers: none # rbd status rbd-technet/vm-402-disk-1 Watchers: none Normal image vs problematic: # rbd object-map check rbd-technet/vm-402-disk-0 Object Map Check: 100% complete…done. # rbd object-map check rbd-technet/vm-402-disk-1 ^C disk-0 is good while disk-1 is effectively lost.

Choosing suitable SSD for Ceph cluster

by Hermann Himmelbauer

Hi, I am running a nice ceph (proxmox 4 / debian-8 / ceph 0.94.3) cluster on 3 nodes (supermicro X8DTT-HIBQF), 2 OSD each (2TB SATA harddisks), interconnected via Infiniband 40. Problem is that the ceph performance is quite bad (approx. 30MiB/s reading, 3-4 MiB/s writing ), so I thought about plugging into each node a PCIe to NVMe/M.2 adapter and install SSD harddisks. The idea is to have a faster ceph storage and also some storage extension. The question is now which SSDs I should use. If I understand it right, not every SSD is suitable for ceph, as is denoted at the links below: https://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-i… or here: https://www.proxmox.com/en/downloads/item/proxmox-ve-ceph-benchmark In the first link, the Samsung SSD 950 PRO 512GB NVMe is listed as a fast SSD for ceph. As the 950 is not available anymore, I ordered a Samsung 970 1TB for testing, unfortunately, the "EVO" instead of PRO. Before equipping all nodes with these SSDs, I did some tests with "fio" as recommended, e.g. like this: fio --filename=/dev/DEVICE --direct=1 --sync=1 --rw=write --bs=4k --numjobs=1 --iodepth=1 --runtime=60 --time_based --group_reporting --name=journal-test The results are as the following: ----------------------- 1) Samsung 970 EVO NVMe M.2 mit PCIe Adapter Jobs: 1: read : io=26706MB, bw=445MiB/s, iops=113945, runt= 60001msec write: io=252576KB, bw=4.1MiB/s, iops=1052, runt= 60001msec Jobs: 4: read : io=21805MB, bw=432.7MiB/s, iops=93034, runt= 60001msec write: io=422204KB, bw=6.8MiB/s, iops=1759, runt= 60002msec Jobs: 10: read : io=26921MB, bw=448MiB/s, iops=114859, runt= 60001msec write: io=435644KB, bw=7MiB/s, iops=1815, runt= 60004msec ----------------------- So the read speed is impressive, but the write speed is really bad. Therefore I ordered the Samsung 970 PRO (1TB) as it has faster NAND chips (MLC instead of TLC). The results are, however even worse for writing: ----------------------- Samsung 970 PRO NVMe M.2 mit PCIe Adapter Jobs: 1: read : io=15570MB, bw=259.4MiB/s, iops=66430, runt= 60001msec write: io=199436KB, bw=3.2MiB/s, iops=830, runt= 60001msec Jobs: 4: read : io=48982MB, bw=816.3MiB/s, iops=208986, runt= 60001msec write: io=327800KB, bw=5.3MiB/s, iops=1365, runt= 60002msec Jobs: 10: read : io=91753MB, bw=1529.3MiB/s, iops=391474, runt= 60001msec write: io=343368KB, bw=5.6MiB/s, iops=1430, runt= 60005msec ----------------------- I did some research and found out, that the "--sync" flag sets the flag "O_DSYNC" which seems to disable the SSD cache which leads to these horrid write speeds. It seems that this relates to the fact that the write cache is only not disabled for SSDs which implement some kind of battery buffer that guarantees a data flush to the flash in case of a powerloss. However, It seems impossible to find out which SSDs do have this powerloss protection, moreover, these enterprise SSDs are crazy expensive compared to the SSDs above - moreover it's unclear if powerloss protection is even available in the NVMe form factor. So building a 1 or 2 TB cluster seems not really affordable/viable. So, can please anyone give me hints what to do? Is it possible to ensure that the write cache is not disabled in some way (my server is situated in a data center, so there will probably never be loss of power). Or is the link above already outdated as newer ceph releases somehow deal with this problem? Or maybe a later Debian release (10) will handle the O_DSYNC flag differently? Perhaps I should simply invest in faster (and bigger) harddisks and forget the SSD-cluster idea? Thank you in advance for any help, Best Regards, Hermann -- hermann(a)qwer.tk PGP/GPG: 299893C7 (on keyservers)

OSDs get full with bluestore logs

by Khodayar Doustar

Hi, I have a 3 node cluster of mimic with 9 osds (3 osds on each node). I use this cluster to test integration of an application with S3 api. The problem is that after a few days all OSD starts filling up with bluestore logs and goes down and out one by one! I cannot stop the logs and I cannot find the setting to fix this leakage, this should be a leakage in logs because it's not logical to fill up all OSD with bluefs logs. This is an example of logs which is being repeated in bluestore logs: [root@server2 ~]# ceph-bluestore-tool --command bluefs-log-dump --path /var/lib/ceph/osd/ceph-5 . . . 0x40d000: op_file_update file(ino 30 size 0x7a713 mtime 2020-04-18 15:54:29.056488 bdev 1 allocated 80000 extents [1:0x130000+10000,1:0x100000+10000,1:0x140000+10000,1:0x150000+10000,1:0x160000+10000,1:0x170000+10000,1:0x180000+10000,1:0x190000+10000]) 0x40e000: txn(seq 1156100 len 0x78 crc 0x3e1c626f) 0x40e000: op_file_update file(ino 30 size 0x7a72a mtime 2020-04-18 15:54:30.057828 bdev 1 allocated 80000 extents [1:0x130000+10000,1:0x100000+10000,1:0x140000+10000,1:0x150000+10000,1:0x160000+10000,1:0x170000+10000,1:0x180000+10000,1:0x190000+10000]) 0x40f000: txn(seq 1156101 len 0x78 crc 0xc1f9ec5f) 0x40f000: op_file_update file(ino 30 size 0x7a741 mtime 2020-04-18 15:54:31.059252 bdev 1 allocated 80000 extents [1:0x130000+10000,1:0x100000+10000,1:0x140000+10000,1:0x150000+10000,1:0x160000+10000,1:0x170000+10000,1:0x180000+10000,1:0x190000+10000]) *** Caught signal (Segmentation fault) ** in thread 7f4108cfe600 thread_name:ceph-bluestore- ceph version 13.2.8 (5579a94fafbc1f9cc913a0f5d362953a5d9c3ae0) mimic (stable) 1: (()+0xf5f0) [0x7f40fd47f5f0] 2: (BlueFS::_read(BlueFS::FileReader*, BlueFS::FileReaderBuffer*, unsigned long, unsigned long, ceph::buffer::list*, char*)+0x3bf) [0x55603a1ebb3f] 3: (BlueFS::_replay(bool, bool)+0x214) [0x55603a1f6654] 4: (BlueFS::log_dump(CephContext*, std::string const&, std::vector<std::string, std::allocator<std::string> > const&)+0x3b) [0x55603a1fad3b] 5: (log_dump(CephContext*, std::string const&, std::vector<std::string, std::allocator<std::string> > const&)+0x64) [0x55603a1da764] 6: (main()+0x2f3e) [0x55603a105e3e] 7: (__libc_start_main()+0xf5) [0x7f40fbe51505] 8: (()+0x23115f) [0x55603a1d915f] 2020-04-18 21:08:25.410 7f4108cfe600 -1 *** Caught signal (Segmentation fault) ** in thread 7f4108cfe600 thread_name:ceph-bluestore- . . .

Ceph Nautilus packages for Ubuntu Focal

by Stefan Kooman

Hi list, We're wondering if Ceph Nautilus packages will be provided for Ubuntu Focal Fossa (20.04)? You might wonder why one would not just use Ubuntu Bionic (18.04) instead of using the latest LTS. Here is why: a glibc bug in Ubuntu Bionic that *might* affect Open vSwitch (OVS) users [1]. We had quite a few issues with OVS deadlocks on hypervisors, and do not want to risk experiencing the same issues on our Ceph cluster(s). I'm not sure how many of you use OVS for bridging / bonding, but for those who do, running Ceph (Nautlilus / Octopus) on 20.04 would be preferred. Gr. Stefan [1]: https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1839592

Ceph influxDB support versus Telegraf Ceph plugin?

by victorhooi＠yahoo.com

Hi, I've read that Ceph has some InfluxDB reporting capabilities inbuilt (https://docs.ceph.com/docs/master/mgr/influx/). However, Telegraf, which is the system reporting daemon for InfluxDB, also has a Ceph plugin (https://github.com/influxdata/telegraf/tree/master/plugins/inputs/ceph). Just curious what people's thoughts on the two are, or what they are using in production? Which is easier to deploy/maintain, have you found? Or more useful for alerting, or tracking performance gremlins? Thanks, Victor
