Unable to create Index on Mongo Version 4.4.18 on Ubuntu even for small collections
db.currentop() shows as below.
Neither getting error Nor Index being created .
Could someone help on this???
Hello @Geetha_M ,
Welcome to The MongoDB Community Forums! 
I notice you haven’t had a response to this topic yet - were you able to find a solution?
As per the documentation, the waitingForLatch document is only available if the operation is waiting to acquire an internal locking primitive (a.k.a. a latch) or for an internal condition to be met.
“waitingForLatch” : {
“timestamp” : ISODate(“2023-01-27T07:01:57.013Z”),
“captureName” : “IndexBuilds Coordinator::_mutex”
},
Here,
| Output Field | Description |
|---|---|
| timestamp | The date and time at which the operation started to wait. |
| captureName | The internal name of the section where the operation is currently blocked. |
This shows that the index creation command is being executed. Could you share below details for us to understand your use-case better?
- Your createIndex command
- Output for db.collection.stats()
- Is this the first time you are building an index on this collection or is it failing for the first time and index creation was successful before?
- What is your deployment topology?
- Hardware specifications
- Share whole response for db.currentop()
- Check for errors in MongoDB logs
- Check the system resources, like memory and disk space, to make sure there’s enough available to create the index.
