  • When a disk is mounted, its status is read-only.
  • File systems work unexpectedly.
  • Disk hardware is faulty.

Procedure

  1. Check the location information of the alarm.

    1. Use a browser to log in to the FusionStage OM zone console.
      1. Log in to ManageOne Maintenance Portal.
        • Login address: https://Address for accessing the homepage of ManageOne Maintenance Portal:31943, for example, https://oc.type.com:31943.
        • The default username is admin, and the default password is Huawei12#$.
      2. On the O&M Maps page, click the FusionStage link under Quick Links to go to the FusionStage OM zone console.
    2. Choose Application Operations > Application Operations from the main menu.
    3. In the navigation pane on the left, choose Alarm Center > Alarm List and query the alarm by setting query criteria.
    4. Click to expand the alarm information. Record the values of device and hostIP and hostName.

  2. Use PuTTY to log in to the manage_lb1_ip node. Run the following command to ping the IP address of the hostIP and check where the network is normal:

    The default username is paas, and the default password is QAZ2wsx@123!.

    ping hostIP

    • If the network is normal, go to 9.
    • If the network is abnormal, go to 3~8.

  3. Use PuTTY to log in to the manage_lb1_ip node.

    The default username is paas, and the default password is QAZ2wsx@123!.

  4. Run the following command and enter the password of the root user to switch to the root user:

    su - root

    Default password: QAZ2wsx@123!

  5. Run the following command to check whether the node corresponding to the queried hostIP is a management zone node:

    kubectl get node hostName -oyaml | grep 'com.huawei.project/name'

    labels:     
     com.huawei.project/name: fst-manage

    Check whether the value of com.huawei.project/name is fst-manage.

    • If yes, the node is a management zone node. Go to 6.a.
    • If no, the node is a data zone node. Go to 6.b

  6. Query the IP address for logging in to the node.

    1. Run the following command to query InternalIP of the node:

      kubectl get node hostName -oyaml | grep -B 2 InternalIP

    2. Run the following command to query ExternalIP of the node:

      kubectl get node hostName -oyaml | grep ExternalIP

  7. Run the following command switch to the paas user:

    su - paas

  8. Run the following command to go to the node using the IP address queried in 6:

    ssh IP

  9. Use PuTTY to log in to the faulty node based on the value of the hostIP parameter.

    Default username: paas. Default password: QAZ2wsx@123!

  10. Run the following command to check the disk status:

    mount|grep -v /dev/mapper/docker|grep '^/dev'|grep '/dev/vda2'|awk '{print "device="$1", mountOnPath="$3", rwState="$6", length="NF}'

    Information similar to the following is displayed:

    device=/dev/vda2, mountOnPath=/var, rwState=(rw,nodev,relatime,errors=panic,data=ordered), length=6
    1. Use a browser to log in to the FusionStage OM zone console.
      1. Log in to ManageOne Maintenance Portal.

      • If the values are not the same, go to Step 12 .
    3. Check whether the value of length is 6 and the read/write status rwState is ro in the previously displayed information.
      • If the value of length is 6 and the read/write status rwState is ro, go to Step 12.
      • If the value of length is 6 but the read/write status rwState is not ro, go to Step 11.
