Problem with enabling web cache

[MaxKarimov]

Hello.

After deployment MWG in Azure from mwg-10.2.0-37129.vhd have problem with network parameters.

Options are not active.

Also in cli command mwg-cache-wizard take an error: Error: Hard drive needs at least 40GB.

No filesystem with cache.

$ df -H
Filesystem Size Used Avail Use% Mounted on
tmpfs 2.1G 9.0M 2.1G 1% /run
devtmpfs 2.1G 0 2.1G 0% /dev
tmpfs 2.1G 13M 2.1G 1% /dev/shm
/dev/sda 271G 3.7G 256G 2% /
tmpfs 2.1G 0 2.1G 0% /sys/fs/cgroup
/dev/sdb1 8.4G 38M 7.9G 1% /mnt/resource
tmpfs 414M 0 414M 0% /run/user/10000

It differes from another proxy server which was deployed from iso file in hypervisor:

# df -H
Filesystem Size Used Avail Use% Mounted on
tmpfs 17G 161M 17G 1% /run
devtmpfs 17G 0 17G 0% /dev
tmpfs 17G 15M 17G 1% /dev/shm
/dev/sda1 9.6G 2.2G 6.9G 24% /
tmpfs 17G 0 17G 0% /sys/fs/cgroup
/dev/mapper/vg00-var 16G 276M 15G 2% /var
/dev/mapper/vg00-tmp 5.1G 11M 4.8G 1% /tmp
/dev/mapper/vg00-opt 29G 3.9G 24G 15% /opt
/dev/mapper/vg00-cache 29G 20G 8.4G 71% /opt/mwg/cache
tmpfs 3.4G 0 3.4G 0% /run/user/199
tmpfs 3.4G 0 3.4G 0% /run/user/0

Should I make some post configuration on server after deployment it in Azure from vhd file?

Web cache can not be enabled. Proxy  take an error:

Dear @MaxKarimov 

unfortunately i cant find anything about caching in Azure or AWS. The partition table is definitely different which might be the reason "cache" isnt available. Please create service request with the link to the community so we can check this with engineering and provide you official response.
