when many users are running searches during meetings, we do see errors related to underlying storage issues.
this happens only when many users are on the search head.
i am not sure if we can resolve this problem over the community , but any insights or ideas that i can consider to make it better.
already i am looking to cluster the indexers + cluster the search heads with multi site configuration.
what kind of errors? As you know, when a lot of concurrent searches run, it adds pressure on the IOPS on the storage layer and also consumes disk space for the users.
I assume you may have some custom role/storage setting to limit the disk space used by users. This way you can protect the SHs by not running out of disk space and also allow a better user experience by queing mutliple search requests from same users.
Yes, increasing storage/IOPS, clustering, limiting user disk quota etc.. will also help.
