DSVM mounted file store freezing

    Question

  • I am having intermittent issues with a file store mount on a Linux VM. The problem I am having is that intermittently the mount seems to freeze and I am unable to access it or even unmount it. For now my only solution is to reboot the machine. Is there some setting that I am missing that would prevent this freezing? The VM image used is the Data Science VM.

  • Hi MSalvaris,

    Thank you for posting here! We are happy to assist you.

    1. Are you using the Azure Files or Cloud Drive?
    2. Is it IaaS VM or a PaaS VM?

    Regards,

  • Hi,

    To troubleshoot this issue more efficiently, could you show me some information about your case:

    1 Which version of your Linux VM?

    2 The file store is an attached disk or the azure file storage?

    3 Could you show me the configuration of your /etc/fstab?

    If you still have questions, welcome to post back here. Thanks.

    Best Regards,

  • Hi Sumanth,

    I am using File storage in an Azure Storage Account I created in the Azure portal. 

    I am using the data science VM which I am guessing is IaaS but not 100% sure.

    Best,

  • Not sure which version specifically I am running but I am using the data science VM which I believe is the standard CentOS VM with added data science tools. If you can point me to some instructions to determine which version exactly I would be happy to oblige.

    It is Azure File storage.

    I am not mounting it fstab I mount it using the following:

    sudo mount -t cifs $STORAGE_URI $MOUNT_POINT -o vers=3.0,username=$ACCOUNT_NAME,password=$ACCOUNT_KEY,dir_mode=0777,file_mode=0777

    Best,

  • Hi,

    According to your description, maybe we should add the configuration to /etc/fstab:

    //myaccountname.file.core.windows.net/mysharename /mymountpoint cifs vers=3.0,username=myaccountname,password=StorageAccountKeyEndingIn==,dir_mode=0777,file_mode=0777

    To troubleshoot this issue more efficiently, may you post the logs from the /var/log/message about mount.

    If you still have questions, welcome to post back here. Thanks.
