Hello :
We are having Elasticsearch version 7.8.0 , running with 6 node cluster.
All 6 nodes were data and master nodes.
We have lost 3 Nodes out of 6 , and now we have message in logfile
`[2023-02-14T10:58:47,994][WARN][o.e.c.c.ClusterFormationFailureHelper] [node-3] master not discovered or elected yet, an election requires at least 3 nodes with ids from [mD9UOfWDR_SL8XOsnvyCNQ, anO0mFz5Qgui3pSGiJI2VQ, jTop1VSZQMOcQBcR8vag2g, -8Oash5YSu6Jc8HWdzzthg, YNoy2TZDQ96amRr5prh8yw], have discovered [{node-3}{nkyEDQQVQieuz2Gn7Y6nMQ}{mef9dxGfRVOANdBBiP5tiQ}{172.24.22.221}{172.24.22.221:9300}{dilmrt}{ml.machine_memory=33511661568, rack=r1, xpack.installed=true, transform.node=true, ml.max_open_jobs=20}, {node-rh-1}{YNoy2TZDQ96amRr5prh8yw}{IMlQXxgHRAOynU_OinrNCw}{172.24.22.183}{172.24.22.183:9300}{dilmrt}{ml.machine_memory=33511661568, rack=r1, ml.max_open_jobs=20, xpack.installed=true, transform.node=true}, {node-rh-2}{jTop1VSZQMOcQBcR8vag2g}{u13k64eHSoaodxEGbVegcg}{172.24.22.126}{172.24.22.126:9300}{dilmrt}{ml.machine_memory=33511661568, rack=r1, ml.max_open_jobs=20, xpack.installed=true, transform.node=true}] which is not a quorum; discovery will continue using [172.24.22.183:9300, 172.24.22.126:9300] from hosts providers and [{node-3}{nkyEDQQVQieuz2Gn7Y6nMQ}{mef9dxGfRVOANdBBiP5tiQ}{172.24.22.221}{172.24.22.221:9300}{dilmrt}{ml.machine_memory=33511661568, rack=r1, xpack.installed=true, transform.node=true, ml.max_open_jobs=20}] from last-known cluster state; node term 10, last-accepted version 3258 in term 10`
ELASTICSEARCH is looking for Nodes with ID's
[mD9UOfWDR\_SL8XOsnvyCNQ, anO0mFz5Qgui3pSGiJI2VQ, jTop1VSZQMOcQBcR8vag2g, -8Oash5YSu6Jc8HWdzzthg, YNoy2TZDQ96amRr5prh8yw]
We are having only below nodes :
[node-rh-2], node ID [jTop1VSZQMOcQBcR8vag2g],
[node-rh-3], node ID [nkyEDQQVQieuz2Gn7Y6nMQ]
[node-rh-1], node ID [YNoy2TZDQ96amRr5prh8yw]
Hence would like your help , if you could help me how to fix this forcefully and make up cluster.
1. How to fix the quorum with available nodes
2. How to fix UUID for a node during startup so that , atleast my cluster would start.
3. I do not have BACKUP of my data.

Okay , we have fixed the issue by following the document :
