The important part (and missing from your post) is how much of that allocated space is actually "in-use"? If you are using all 8TB of hot and 160TB of cold, then there is no way around it - you need more disk. However, if your true usage of space falls below this, then you can set your limits to match the space that is available. For example. if your only using 4TB of your 8TB actual hot-device you can safely amend the maxVolumeDataSizeMB to 1TB on each host. You should also understand that if you set the maxVol.. to a value smaller than what you have in current use will only cause that data to roll to cold - not be removed. The limits only tell Splunk what to do at those limits, so as long as you have a small amount of Cold space you can add your new indexers leaving the cold  maxVol... set to 40TB each (320 total) Let the cluster replicate and balance, then when that process is complete you can reduce it to 20TB each. But, Ideally your retention should be dictated by dates rather than volume. I tend to think of the maxVol.. setting as a safety net incase you are getting close to the physical limits of the hardware, but what really drives my storage is how long i need to keep that data for.   ...

@splunkreal wrote: So sc4s is just a filter, we can't use it as log collector to store data for several months if I understood? That is correct. SC4S is a transient combined syslog receiver and Splunk forwarder. It is not a useful tool without a platform (Splunk) to send the data to. The big advantage with SC4S is the "rule soup" which helps classify and route data into appropriate sourcetypes and indexes without needing any further configuration ... View more

If your metrics are coming from the nix or windows TA then changing the DS version would not have any effect as it is the TA providing that data not the Splunk version.  With that said, so far, my limited testing of v9 I haven’t seen any differences in any of the internal metrics either, so you *should* be ok.  if you need anything further you are better off starting a new topic so more people will see your question!  ...

I think the wording is a little confusing, but "tstatsHomePath" allows you to dictate where this data is stored if you wanted to separate it from the rest of your index data, but importantly you do not have to specify a "tstatsHomePath"! The wording in the spec file says that you should not configure this value for an index with remote storage, so this just means for a Smartstore index do not define "tstatsHomePath"  - the cachemanager will handle this for you.     ...

If the syslog receiver is using UDP you can't test it with telnet, instead try netcat. nc -z -v -u <your_IP> <your_port_number>   Although, a good start is to use netstat on the recieving host and confirm the host is listening on the right interface/port/proto! netstat -ln|grep <your_port_number>   ...

Splunk will not perform CIDR matches against regular expressions. You will need to construct your regex to match the range of addresses you need   (10\.) (172\.1[6-9]\.)|(172\.2[0-9]\.)|(172\.3[0-1]\.) (192\.168\.)   But you should be able to do this in one stanza if you wish   [internal_IPs] REGEX = dst\=((?:10\.)|(?:172\.1[6-9]\.)|(?:172\.2[0-9]\.)|(?:172\.3[0-1]\.)|(?:192\.168\.)).+ DEST_KEY = queue FORMAT = nullQueue   ...

Was Splunk configured to run as "root"? If you configured Splunk to run as "splunk" (recommended) you should not start it as root. If you do, it may mess about with the folder permissions, which means the next time you start it as "splunk" you get permission errors. If this is what happened, you should stop Splunk (if running) then (assuming linux) sudo chown -R splunk:splunk /opt/splunk   Then start Splunk as "splunk" - probably easier to reboot the system and let the Splunk boot-start process handle it.   ...
