Hey Gentsrunning ard 7-10 containers on my Debian 11,I found my /var/lib/docker/overlay2 folder increase abt 300MB daily and it is endlessI did some homework here and known that is folder is something about docker file system and tried all prune comments with varity of options ,but can not reclaim any space.Since I dont know how to delete something yet ,I should at least firgure out what is growningso I run flwg commends every morningdf -hcd /var/lib/docker/overlay2du -h --max-depth=1df -h shows /var/lib/docker/overlay2 grows about 300MB dailybut the after checking du comment output ,I found the outputs are exactly same as yestadaydf reports growing but du reports sameI learned that du/df has different calculation ,but how can I fix this problem?it is fine that overlay take a lot of space to me but I cant leave it growing endlessly without deploy new containersdocker -versionDocker version 20.10.13, build a224086 meyay (Metin Y.) April 24, 2022, 10:03am 2 Try:du --human-readable --max-depth 1 --no-dereference --one-file-system /var/lib/docker/overlay2du ist not realy equiped to determine the size for a “composed” filesystem like overlay2, where you have a lower, upper, merged and workdir, thus counting the very same files more than once.df on the other hand shows the real occupied size.You might want to regularly check du --human-readable --max-depth 1 --no-dereference --one-file-system /var/lib/docker and see where the growth actualy happens.If you would have said that df shows growth, it might have been explainable with logs beeing written in the container filesystem. If the growth is not in the overlay2 it could still be container logging gone wild. xiaoyuesanshui (Xiaoyuesanshui) April 24, 2022, 12:32pm 3 Thanks Meyayyes, I also learned du output is not real occupation ,which I am fine with thatYou might want to regularly check du --human-readable --max-depth 1 --no-dereference --one-file-system /var/lib/docker and see where the growth actualy happens.yes, I only focused on the /var/lib/docker/overlay2 but overlooked the docker folder and I will check in the futureIf you would have said that df shows growth, it might have been explainable with logs beeing written in the container filesystem.I shutdown couple of containers ,remain one or two really essential

'overlay2' is not supported over overlayfs storage-driver=overlay2

Is there an existing issue for this? I have searched the existing issues before opening this issue.Current BehaviorWhen I try to start my server I get the error that the Docker driver "overlay2" failed to remove root filesystem.

Image:You can use multiple -H, for example, if you want to listen on bothTCP and a Unix socketDaemon storage-driverOn Linux, the Docker daemon has support for several different image layer storagedrivers: overlay2, fuse-overlayfs, btrfs, and zfs.overlay2 is the preferred storage driver for all currently supported Linux distributions,and is selected by default. Unless users have a strong reason to prefer another storage driver,overlay2 should be used.You can find out more about storage drivers and how to select one inSelect a storage driver.On Windows, the Docker daemon only supports the windowsfilter storage driver.Options per storage driverParticular storage-driver can be configured with options specified with--storage-opt flags. Options for zfs start with zfs, and options forbtrfs start with btrfs.ZFS optionszfs.fsnameSpecifies the ZFS filesystem that the daemon should use to create its datasets.By default, the ZFS filesystem in /var/lib/docker is used.ExampleBtrfs optionsbtrfs.min_spaceSpecifies the minimum size to use when creating the subvolume which is usedfor containers. If user uses disk quota for btrfs when creating or runninga container with --storage-opt size option, Docker should ensure thesize can't be smaller than btrfs.min_space.ExampleOverlay2 optionsoverlay2.sizeSets the default max size of the container. It is supported only when thebacking filesystem is xfs and mounted with pquota mount option. Under theseconditions the user can pass any size less than the backing filesystem size.ExampleWindowsfilter optionssizeSpecifies the size to use when creating the sandbox which is used for containers.Defaults to 20G.ExampleRuntime optionsThe Docker daemon relies on aOCI compliant runtime(invoked via the containerd daemon) as its interface to the Linuxkernel namespaces, cgroups, and SELinux.Configure container runtimesBy default, the Docker daemon uses runc as a container runtime.You can configure the daemon to add additional runtimes.containerd shims installed on PATH can be used directly, without the needto edit the daemon's configuration. For example, if you install the KataContainers shim (containerd-shim-kata-v2) on PATH, then you can select thatruntime with docker run without having to edit the daemon's configuration:Container runtimes that don't implement containerd shims, or containerd shimsinstalled outside of PATH, must be registered with the daemon, either via theconfiguration file or using the --add-runtime command line flag.For examples on how to use other container runtimes, seeAlternative container runtimesConfigure runtimes using daemon.jsonTo register and configure container runtimes using the daemon's configurationfile, add the runtimes as entries under runtimes:The key of the entry ( in the previous example) represents the nameof the runtime. This is the name that you reference when you run a container,using docker run --runtime .The runtime entry contains an object specifying the configuration for yourruntime. The properties of the object depends on what kind of runtime you'relooking to register:If the runtime implements its own containerd shim, the object shall containa runtimeType field and an optional options field.SeeConfigure shims.If the runtime is designed to be a

Container running and I can found by df that growth is still there, about 1MB per hour ,more or less, longer or shortermay I know if that would be a good idea to locate where the growth is by du /var/lib/docker?thanksB.RGDS xiaoyuesanshui (Xiaoyuesanshui) April 24, 2022, 12:45pm 4 Hello Meyayfurther belowdf on the other hand shows the real occupied size.but when I df -h ,it shows overlay takes great space in my system ,and when it eats all space, the dokcer would return errorhow can I deal with that toohere are my df -h output文件系统 容量space 已用used 可用avail 已用%used% mount point/dev/mapper/Debian–vg-var 8.1G 7.5G 157M 98% /var/dev/mapper/Debian–vg-home 92G 1.6G 86G 2% /home/dev/mapper/bookVG-bookLV 459G 244G 192G 56% /home/bing/NAS/book/dev/mapper/mailVG-mailLV 459G 602M 435G 1% /home/bing/mail/dev/mapper/cloudVG-cloudLV 1.4T 669G 647G 51% /home/bing/super_nextcloud/app/data/dev/mapper/videoVG-videoLV 12T 8.7T 2.6T 78% /home/bing/NAS/video/dev/mapper/softwareVG-softwareLV 2.3T 884G 1.3T 41% /home/bing/NAS/software/dev/mapper/pictureVG-pictureLV 917G 443G 432G 51% /home/bing/NAS/picturetmpfs 796M 0 796M 0% /run/user/1000 meyay (Metin Y.) April 24, 2022, 1:17pm 5 Well, df shows how the free/used capacity of a partition is, not how much a folder in the partition uses.Generaly you will have a hard time to run containers with just 8.1G for /var shared with the system.You will want to have at least 30G, better 40G in a dedicated volume group mounted into /var/lib/docker. 30 or 40 even larger is fine ,that is an LVM device in my system ,easily to expandbut the key point is ,I need to locate where and why the size is growing meyay (Metin Y.) April 24, 2022, 1:39pm 7 This is a way to figure out if it’s realy the overlay2 or maybee the container subfolder.Make sure the containers ment to be run permanently are not logging with a log-level of debug or trace.
