Ubuntu AZ CLI and mount fileshare (az login)

Install the Azure CLI on Linux

# ssh to vm
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

#update Azure CLI

az upgrade
az version
azure-cli, 2.53.1
az login --tenant
# follow webpage and paste code and login

Mount SMB Azure file share on Linux

Assuming you have made a fileshare on a storage account.

Prerequisites:

sudo apt update
sudo apt install cifs-utils

Test 445

# This command assumes you have logged in with az login
RESOURCE_GROUP_NAME="<your-resource-group>"
STORAGE_ACCOUNT_NAME="<your-storage-account>"

# This command assumes you have logged in with az login
HTTP_ENDPOINT=$(az storage account show --resource-group $RESOURCE_GROUP_NAME --name $STORAGE_ACCOUNT_NAME --query "primaryEndpoints.file" --output tsv | tr -d '"')
SMBPATH=$(echo $HTTP_ENDPOINT | cut -c7-${#HTTP_ENDPOINT})
FILE_HOST=$(echo $SMBPATH | tr -d "/")

nc -zvw3 $FILE_HOST 445

Mount the Azure file share on-demand with mount

When you mount a file share on a Linux OS, your remote file share is represented as a folder in your local file system. You can mount file shares to anywhere on your system. The following example mounts under the /media path. You can change this to your preferred path you want by modifying the $MNT_ROOT variable.

RESOURCE_GROUP_NAME="<resource-group-name>"
STORAGE_ACCOUNT_NAME="<storage-account-name>"
FILE_SHARE_NAME="<file-share-name>"

MNT_ROOT="/media"
MNT_PATH="$MNT_ROOT/$STORAGE_ACCOUNT_NAME/$FILE_SHARE_NAME"

sudo mkdir -p $MNT_PATH

Next, mount the file share using the mount command

RESOURCE_GROUP_NAME="<resource-group-name>"
STORAGE_ACCOUNT_NAME="<storage-account-name>"
FILE_SHARE_NAME="<file-share-name>"

# This command assumes you have logged in with az login
HTTP_ENDPOINT=$(az storage account show --resource-group $RESOURCE_GROUP_NAME --name $STORAGE_ACCOUNT_NAME --query "primaryEndpoints.file" --output tsv | tr -d '"')
SMB_PATH=$(echo $HTTP_ENDPOINT | cut -c7-${#HTTP_ENDPOINT})$FILE_SHARE_NAME

STORAGE_ACCOUNT_KEY=$(az storage account keys list --resource-group $RESOURCE_GROUP_NAME --account-name $STORAGE_ACCOUNT_NAME --query "[0].value" --output tsv | tr -d '"')

sudo mount -t cifs $SMB_PATH $MNT_PATH -o username=$STORAGE_ACCOUNT_NAME,password=$STORAGE_ACCOUNT_KEY,serverino,nosharesock,actimeo=30,mfsymlinks

We just installed cifs and there is an error for the last line

mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Do a reboot.

ssh
az login --tenant 

RESOURCE_GROUP_NAME="<resource-group-name>"
STORAGE_ACCOUNT_NAME="<storage-account-name>"
FILE_SHARE_NAME="<file-share-name>"

# This command assumes you have logged in with az login
HTTP_ENDPOINT=$(az storage account show --resource-group $RESOURCE_GROUP_NAME --name $STORAGE_ACCOUNT_NAME --query "primaryEndpoints.file" --output tsv | tr -d '"')
SMB_PATH=$(echo $HTTP_ENDPOINT | cut -c7-${#HTTP_ENDPOINT})$FILE_SHARE_NAME

STORAGE_ACCOUNT_KEY=$(az storage account keys list --resource-group $RESOURCE_GROUP_NAME --account-name $STORAGE_ACCOUNT_NAME --query "[0].value" --output tsv | tr -d '"')

sudo mount -t cifs $SMB_PATH $MNT_PATH -o username=$STORAGE_ACCOUNT_NAME,password=$STORAGE_ACCOUNT_KEY,serverino,nosharesock,actimeo=30,mfsymlinks

error, can’t find in /etc/fstab.

We need to add the share vars for mount, since we logged out.

RESOURCE_GROUP_NAME="<resource-group-name>"
STORAGE_ACCOUNT_NAME="<storage-account-name>"
FILE_SHARE_NAME="<file-share-name>"

MNT_ROOT="/media"
MNT_PATH="$MNT_ROOT/$STORAGE_ACCOUNT_NAME/$FILE_SHARE_NAME"

sudo mkdir -p $MNT_PATH

# The run the last line again
sudo mount -t cifs $SMB_PATH $MNT_PATH -o username=$STORAGE_ACCOUNT_NAME,password=$STORAGE_ACCOUNT_KEY,serverino,nosharesock,actimeo=30,mfsymlinks

same error

mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

linux-image-6.2.0-1016-azure cifs is not supported – Microsoft Q&A

sudo apt install -y linux-modules-extra-azure
# The run the last line again
sudo mount -t cifs $SMB_PATH $MNT_PATH -o username=$STORAGE_ACCOUNT_NAME,password=$STORAGE_ACCOUNT_KEY,serverino,nosharesock,actimeo=30,mfsymlinks

error

mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

# I added the account key here, but no need, it is a var from above, oink.
sudo mount -t cifs $SMB_PATH $MNT_PATH -o username=$STORAGE_ACCOUNT_NAME,password=$STORAGE_ACCOUNT_KEY,serverino,nosharesock,actimeo=30,mfsymlinks

Success, lets see.

Create a folder and a file

View in in the storage account

Next day, on boot it was gone. Start here.

Did this

Went to portal and copied the script on connect after choosing linux

#list all shares
mount

sudo umount -l //sharename.file.core.windows.net/ansibleshare

sudo nano mount_share.sh
# paste the script in and run it
bash mount_share.sh

cd /mnt/ansibleshare
# and folder 1 is there

restart vm

Success, folder1 is there and we can create folders.

After second restart:

Args, the the initial steps again.

Code

RESOURCE_GROUP_NAME="---------------"
STORAGE_ACCOUNT_NAME="----------------"
FILE_SHARE_NAME="------------------"

MNT_ROOT="/media"
MNT_PATH="$MNT_ROOT/$STORAGE_ACCOUNT_NAME/$FILE_SHARE_NAME"

sudo mkdir -p $MNT_PATH

az login --tenant

# This command assumes you have logged in with az login
HTTP_ENDPOINT=$(az storage account show --resource-group $RESOURCE_GROUP_NAME --name $STORAGE_ACCOUNT_NAME --query "primaryEndpoints.file" --output tsv | tr -d '"')
SMB_PATH=$(echo $HTTP_ENDPOINT | cut -c7-${#HTTP_ENDPOINT})$FILE_SHARE_NAME

STORAGE_ACCOUNT_KEY=$(az storage account keys list --resource-group $RESOURCE_GROUP_NAME --account-name $STORAGE_ACCOUNT_NAME --query "[0].value" --output tsv | tr -d '"')

sudo mount -t cifs $SMB_PATH $MNT_PATH -o username=$STORAGE_ACCOUNT_NAME,password=$STORAGE_ACCOUNT_KEY,serverino,nosharesock,actimeo=30,mfsymlinks

and we see the two folder again

Make a new folder and restart the vm, again….

Now restart

/media/staccount—-/ansibleshare has no files

mount gives /mnt

/mnt/ansibleshare has all files

folder1 folder2 test1 test2_after_2_time

update a file and check in on the storage account

ok, then new files is there…..

Seems ok now, it seems ubuntu moves it from /media to /mnt on boot
