Hello everyone,
I need some help for a discussion:
I have an Elasticsearch cluster running with three nodes: node 1, node 2, and node 3.
-
Node 1 is the master node
-
Node 2 is the hot node
-
Node 3 is the warm node
Currently, node 2's storage is almost full at 97%.
I decided to add more storage from ESXi because I still have 1TB of free storage there.
After mounting the new storage to node 2, I accidentally ran fdisk /dev/sdb and wrote to it.
Without realizing, /dev/sdb was already part of an LVM, which caused the LVM to go missing.
However, Elasticsearch is still running normally at this moment.
My question is: what is the impact if I run
sudo vgreduce --removemissing --force ubuntu-vg
considering that /var/lib/elasticsearch is also on the same volume group?
If I run that command, will Elasticsearch crash?
