elastic snapshot on shared folder problem if using sshfs

if you want to set path.repo on mounted dir for elasticsearch snapshot. You probably will get this permission error, even though the dir seems writable by all user.
java.lang.IllegalStateException: Unable to access 'path.repo' (/mnt/remote_snapshot_on_st02/snap_dir) at org.elasticsearch.bootstrap.FilePermissionUtils.addDirectoryPath(FilePermissionUtils.java:66) ~[elasticsearch-8.8.1.jar:?]
This happen because elasticsearh process is own by user elasticsearch. You need to mount the dir using elasticsearch acc. sudo su -u elasticsearch sshfs myacc@10.10.10.10:/data/my_elastic_snapshot_dir/ /mnt/my_snapshot_dir Of course you need to have set path.repo on your elasticsearch.yml path.repo: [/mnt/my_snapshot_dir/the_snapshot_dir_on_remote]
