Engineering Team, which is subscribed to cloud-init. https://bugs.launchpad.net/bugs/1779207 Title: Failed mount of '/dev/sdb1' with Swap File cloud-init config Status in cloud-init: Expired Bug description: Environment : RHEL 7.5 on Azure, using cloud-init 18.2 rebase with these patches: https://git.launchpad.net/cloud- init/commit/?id=aa4eeb80 Scenario: I provision an image with the above on Azure, in addition, i apply this cloud-init config: #cloud-config disk_setup: ephemeral0: table_type: gpt layout: [66, [33, 82]] overwrite: True fs_setup: - device: ephemeral0.1 filesystem: ext4 - device: ephemeral0.2 filesystem: swap mounts: - ["ephemeral0.1", "/mnt"] - ["ephemeral0.2", "none", "swap", "sw", "0", "0"] The VM provisions successfully, you see /sdb1 gets mounted and the swap file config succeeds. If i deallocate the VM and start it, /sdb1 does not get mounted, you see the errors below. 2018-06-20 19:50:38,138 - util.py[WARNING]: Failed reading the partition table Unexpected error while running command. Command: ['/usr/sbin/blockdev', '--rereadpt', '/dev/sdb'] Exit code: 1 Reason: - Stdout: Stderr: blockdev: ioctl error on BLKRRPART: Device or resource busy 2018-06-20 19:50:38,138 - util.py[DEBUG]: Failed reading the partition table Unexpected error while running command.

I check fstab: UUID=6e4681f0-1ec3-4c27-9c16-afb90a4c4513 / xfs defaults 0 0 UUID=f2116236-4be6-4b72-b107-c2d7a68688c4 /boot xfs defaults 0 0 /dev/disk/cloud/azure_resource-part1 /mnt auto defaults,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig 0 2 /dev/disk/cloud/azure_resource-part2 none swap sw,comment=cloudconfig 0 0 As a test, i changed the FSTAB entry for the swap to add a dependency on cloud-init: /dev/disk/cloud/azure_resource-part2 none swap sw,nofail,x-systemd.requires=cloud-init.service,comment=cloudconfig 0 0 I deallocated and started the VM, sdb mounts correctly, but the FSTAB is overwritten for swap with the previous config. I modified the FSTAB again, with the addition, then rebooted, again, everything works. Does azure_resource-part2 need a dependency like azure_resource-part1? You can also test this using the existing Azure cloud-init preview images (cloud-init 0.7.9.x) az vm create --resource-group rgName --name vmName --image RedHat:RHEL:7-RAW-CI:latest --admin-username anotherusr --custom-data /../swapconfig.txt --ssh-key-value /.../my.pub az vm deallocate --resource-group rgName --name vmName az vm start --resource-group rgName --name vmName Thanks, Related bugs: * bug 1785354: /etc/fstab: fs_passno is 0 for all file systems To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1779207/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
