@iankitkumar  Yes I did get it to work.  But depends on how the disks and mount points are setup on the existing host.  If the OS disk and Splunk disk are separate with distinct Volume Groups then a disk swap should work.   For example, on a linux host where sda is the OS disk and sdb is the Splunk disk with mountpoint /opt/splunk.   Here are the steps.   Note: I install with .tgz files not rpm.  Of course test in your dev environment 1st!! 1 install same version of Splunk on the new host with new Linux OS version (I use same username/pwd that I used to install Splunk on the existing host) 2 enable boot-start with systemd managed and verify install runs correctly 3 shut down the old and new hosts 4 swap the disk 5 rename/reIP and open required firewalld ports (if needed for your environment) to verify its working. IF you cannot do a disk swap (because the host is not configured to do so) you can always tar up /opt/splunk and untar over /opt/splunk on the new host (on top of the fresh install of splunk (same version)).  Documentation describes this method >>>  Migrate a Splunk Enterprise instance from one physical machine to another - Splunk Documentation Your Splunk Enterprise installation is on an operating system that either your organization or Splunk no longer supports, and you want to move it to an operating system that does have support.

@siemless  This may be best to discuss in the Slack Users but I could not find you so I will respond here. In some cases, I have boxes where the /opt/splunk dir is mounted to a separate drive w/ mount point /opt/splunk.  In that case you can just swap the disk, I learned this method from AWS support.  But that takes preplanning. In some cases, I have boxes that are jacked up, either volume issues across multiple disks or  just not setup to swap disks.  In that case you can use the Splunk docs >>> https://docs.splunk.com/Documentation/Splunk/9.2.1/Installation/MigrateaSplunkinstance I argued with Splunk about the documentation steps but they claim the steps are correct, although I still believe confusing.  FWIW this is what I did... 1 >Create a new host with new OS (in my case I  rename /re-IP to the original afterward). 2 > Install the same version of Splunk on new host (I used a .tar), set systemd, set same admin pwd, then stop Splunkd, maybe test a restart and reboot, to verify. 3 > Stop Splunkd on old host, tar up /opt/splunk, copy over the old.tar to new box, untar over the new install, then start Splunkd. That worked for me, and going fwd all new hosts will be configured for the disk-swappable process. Good luck ... View more

Ok thank you for the clarity... I think someone should revise those steps then, its ambiguous. ... View more

Thank you for the reply. RE: "swap" method, yeah I thought about that and also share your apprehension. RE: " deploy new component", yeah I agree with that method for idxc peers and shc members... But check this out... please LMK what you think Per Splunk docs >>> docs.splunk.com/Documentation/Splunk/9.2.0/Installation/MigrateaSplunkinstance "Migrate a Splunk Enterprise instance from one physical machine to another" "When to migrate" "Your Splunk Enterprise installation is on an operating system that either your organization or Splunk no longer supports, and you want to move it to an operating system that does have support." "How to migrate" The Steps say >>> Stop Splunk Enterprise services on the host from which you want to migrate. Copy the entire contents of the $SPLUNK_HOME directory from the old host to the new host. Copying this directory also copies the mongo subdirectory. Install Splunk Enterprise on the new host. The way I read this is... 1) Stop Splunk on the old box 2) tar up the /opt/splunk on the old box e.g. > tar -cjvf $(hostname)_splunk-og.tar.bz2 --exclude=./var/* --exclude=./$(hostname)*bz2 ./ 3) move and untar the .bz2 file on the new box in /opt  e.g. > tar -xjvf <hostname>_splunk-og.tar.bz2 -C /opt/splunk 4 ) install a clean copy (downloaded from Splunk) of the same version of Splunk on top of the old copies Apparently someone that documented this believes this is the way to go... What do you think? RE: my --exclude=./var/* that is for boxes that don't contain indexed data RE: my --exclude=./$(hostname)*bz2./  this is because I am running the tar from /opt/splunk dir Thank you ... View more

Thank you for the reply.  I also looked at this log but it requires curating an exact list of the UFs, bc I have some pollution, e.g. h= HFs, SC4S, etc.  The license_usage log may be the best route if I can put together a lookup of just UFs. ... View more

POA 1) disable KVstore on the indexer instances only 2) update KVstore all other Splunk instances with a "ready" enabled KVstore to be safe.  **In my case, all instances are default enabled ** Hopefully everything goes well! I will post if it goes sideways. ... View more

Well, in line with your recommendations... I am being advised by Internal Splunk Personnel, to upgrade everything except indexers... My feeling is to disable the kvstore on the indexers but not the other nodes like IDXcluster master etc... Would you agree? (you can conclude that I value your opinion with equal weight as support 😉, maybe more)   ... View more

Thanks for the clarification (and persevering thru my questions).  I really do appreciate it! My concerns, re: IDXCluster and KVstore, are due to all the non-sensical configurations the previous admins left for me.... It would not surprise me to see something unusual here, as I have seen some really goofy stuff.   For instance , I am concerned they did some sort of remote kvstore replication/sync to the indexer peers etc... maybe that doesn't matter, not 100% about that. Would you advise that I "disable" the KVstore on the indexers? for safety? per Splunk docs>>> https://docs.splunk.com/Documentation/Splunk/8.1.3/Admin/AboutKVstore   RE: "upgrade only Search Heads and Heavy Forwarders" ,  I see collections (probably default) on my MC/LM instance and Deployment Server instance as well.  So I am thinking upgrade those as well? IDK. when I run this on my MC/LM instance >>>        | rest splunk_server="local" "/services/search/distributed/peers/" | search disabled=0 | rename peerName AS splunk_server | fields host splunk_server | join type=left splunk_server [| rest splunk_server="*" "/services/kvstore/status" | table splunk_server current.status current.replicationStatus current.storageEngine ] | sort - current.storageEngine         I see every instance (including indexers)  has a default enabled kvstore in "ready"...  So now, knowing this information, does that change your advice? RE: support, IDK, I do feel support should be able to answer these questions.  I get support is "break/fix" but do I really have to break it first to get help or a couple definitive answers? I am sure Support will kick it to our Sales Rep and they will say we need to engage PS for 2 week$ 🤣...   Thank you!   ... View more

Thank you for the response.  You answered me before in another post >> https://community.splunk.com/t5/Deployment-Architecture/In-a-distributed-and-clustered-environ-which-kvstores-need/td-p/633203  upgrade all nodes.  So I presume there is no harm upgrading  a kvstore engine and version on an instance w/ or w/out any active collections? I am scrambled and support won't even give me a definite answer. ... View more

I think, better safe than sorry, looks like some apps use KVstores...  ... View more

Well I understand your point about "this"... but that's the problem, I couldn't find an error with the skipped searches... unless I am missing something. Since I did the rolling restart (reset) there are no more skipped searches. Previously I looked for the longest running searches and none were over-running their schedules, that I could see.  For example one search took an hour approx., but it ran every 4 hours.   Since I did some optimizing there were only 3 scheduled searches that produced the warning which I identified with    index="_internal" sourcetype="scheduler" | eval scheduled=strftime(scheduled_time, "%Y-%m-%d %H:%M:%S") | stats values(scheduled) as scheduled values(savedsearch_name) as search_name values(status) as status values(reason) as reason values(run_time) as run_time values(dm_node) as dm_node values(sid) as sid by _time,savedsearch_name | sort -scheduled | table scheduled, search_name, status, reason, run_time     When I looked back at those 3 specific searches, they were not over-running the schedules, so I was wondering how it got stuck thinking it was "piling up" vs "still running".      I am trying to understand/investigate, if a search is "skipped" then when the shc scheduler retries that previously skipped search at its next runtime, "how can I see that the shc CPT thinks its still running"?  And looking back at the "skipped" events, they don't contain "run_time"...  so I look back historically to find a day with a high value.  But when the searches were running they took max 4 seconds with avg of 2 seconds to complete, which is why I thought the scheduled searches were piling up.  Hope that makes sense. The only other variable I can think of is that these searches are using the "| dbxquery" cmd from Splunk DB Connect app. So did it the SHC just get stuck? Any further thoughts appreciated. TY     ...
