Ana commented on SOLR-12494:
----------------------------

Hi Erick,

I followed your suggestion in migrating the data and swapping the drive
letter and now i ran in the following scenario:

SOLR 1 issues -Server 1

Cannot run zookeeper services on all intances

Error in the zookeeper logs:

Unable to load database on disk
java.io.IOException: The accepted epoch, 19 is less than the current epoch,
63d

Research over the internet
https://issues.apache.org/jira/browse/ZOOKEEPER-2307

Notes:
I can navigate to http://xx.xxx.xxx.xxx:8986/solr/ - however i cannot see
the collections and instances
http://xx.xxx.xxx.xxx:8983/solr/en_cache/admin/ping -ok   --instance 1
http://xx.xxx.xxx.xxx:8984/solr/en_cache/admin/ping - 500 internal
error   --instance
2
http://xx.xxx.xxx.xxx:8985/solr/en_cache/admin/ping - 500 internal
error  --instance
3
http://xx.xxx.xxx.xxx:8986/solr/en_cache/admin/ping - 500 internal
error  --instance
4

SOLR 2 -Server 2

http://xx.xxx.xxx.xxx:8983/solr/en_cache/admin/ping -ok   --instance 1
http://xx.xxx.xxx.xxx:8984/solr/en_cache/admin/ping - 500 internal error
--instance 2
http://xx.xxx.xxx.xxx:8985/solr/en_cache/admin/ping - 500 internal
error  --instance
3
http://xx.xxx.xxx.xxx:8986/solr/en_cache/admin/ping - 500 internal
error  --instance
4
http://localhost:8983/solr/#/en_cache_shard1_replica2- icann see the
collections

All services are started and are in running state

However the error found is:
Zookeeper error: Cannot open channel to X at election address

Architecture:

We have 2 SOLR servers Load balanced SOLR1 and SOLR 2 whereby we have
installed 4 instances on both SOLRs.

Many thanks in advance!!
Ana

> I have the following scenario, I'm having a shared cluster solr installation environment (app server 1-app server 2 load balanced) which has 4 solr instances.
>  
> After reviewing the space audit we have noticed that the partition where the installation resides is too big versus what is used in term of space.
>  
> Therefore we have installed a new drive which is smaller and now we want to migrate from the old dive (E:) to the new drive (F).
>  
> Can you please provide an official answer whether this is a supported scenario?
>  
> If yes, will you please share the steps with us?
