Cluster Volume Error about arnold

[madmatah]

Thanks for your feedback @aarajbhattarai

arnold CLI uses the -f option of readlink that is unsupported by the MacOS version of readlink.
We should fix it to use a POSIX compliant alternative.

In the meantime, I can suggest you to install the coreutils to have a version of readlink that supports the -f option:

brew install coreutils --with-default-names

About sysctl command to tune vm/max_map_count for Elasticsearch, you might try this solution on Mac

File: bin/init-cluster
Objective: Generate an unique identifier for the PV
PV_ID=$(uuidgen)
On Linux this command returns a lowercase string of a UUID.
But on Mac OS X it returning an uppercase string of a UUID.
The solution for MacOs would be
PV_ID=$(uuidgen | tr "[:upper:]" "[:lower:]")
