Description of problem: Unlike every other fedora image, including fedora-atomic, fedora cloud does not ship with an LVM root filesystem. This breaks docker-storage-setup. Even if you attach a secondary disk, start the lvm2-lvmmetad service, create a PV+VG, the script still does not handle this correctly. I've tested this with both the supplied F22 docker and the docker-1.8.1-3.git32b8b25 package that's currently in F23-testing. [fedora@ip-172-21-22-182 ~]$ sudo vgs VG #PV #LV #SN Attr VSize VFree docker 1 0 0 wz--n- 100.00g 100.00g [fedora@ip-172-21-22-182 ~]$ sudo lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT xvda 202:0 0 30G 0 disk └─xvda1 202:1 0 30G 0 part / xvdb 202:16 0 100G 0 disk [fedora@ip-172-21-22-182 ~]$ sudo docker-storage-setup Volume group "xvda1" not found Cannot process volume group xvda1 Path required for Logical Volume "xvda1". Please provide a volume group name Run `lvextend --help' for more information. Metadata volume docker-poolmeta already exists. Not creating a new one. Please provide a volume group name Run `lvcreate --help' for more information. [fedora@ip-172-21-22-182 ~]$ sudo lvs [fedora@ip-172-21-22-182 ~]$ [fedora@ip-172-21-22-182 ~]$
fedora-atomic should be having lvm by default. If not, that's bug and should be fixed. Other regular fedora cloud images don't have lvm by default. And by default a thin pool will not be setup as there is no free space by default on root disk. If you add another disk and configure docker-storage-setup to use that disk,that use case should work though. In you example above, have you told docker-storage-setup about this new volume group "docker"? echo "VG=docker" >> /etc/sysconfig/docker-storage-setup
I just tested F23 beta atomic image and it is shipped with lvm and docker thin pool is setup properly. -bash-4.3# cat /etc/redhat-release Fedora release 23 (Twenty Three) -bash-4.3# vgs VG #PV #LV #SN Attr VSize VFree atomicos 1 2 0 wz--n- 5.70g 1.10g -bash-4.3# lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert docker-pool atomicos twi-a-t--- 1.66g 1.15 0.49 root atomicos -wi-ao---- 2.93g So the issue is only present with fedora cloud images (non-atomic) where lvm is not there and there is no free space on root disk to setup thin pool by default. Adding another disk and specifying that to docker-storage-setup should work. I am also looking into following. - Grow root disk before boot. - Limit the size of rootfs using some cloud-config option (hopefully there is one). - Create a partition and volume group from remaining space on root disk and point docker-storage-setup at it.
Any update on this?
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
Once we get overlayfs into the upstream .next we should pull the kernel patches into Fedora Rawhide and start shipping the cloud image to default to Overlayfs at least in Rawhide.
This bug appears to have been reported against 'rawhide' during the Fedora 25 development cycle. Changing version to '25'.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
