1 OpenSearch Accidentally Deleted Index¶

Problem Description: In some environments with limited disk space, it is necessary to delete indexes, which can easily lead to the accidental deletion of the largest index number, causing Guance kodo-x index writing errors.

Solution:

Using wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging as an example:

Check if the largest index is missing

GET /_alias/wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging



wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000157  -- false
wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000158  -- false
wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000159  -- false

.....

It was found that wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000159 is the largest index, and the next one should be wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000160

Fix the write operation

PUT  wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000160

POST _alias
{
  "actions": [
  {
    "add": 
    {
      "index": "wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging-000160",
      "alias": "wksp_f8f7efcc6c4948ec96c751bbcfb7c8fc_logging",
      "is_write_index": true
    }
  }
  ]
}
