AppetizingMouse58 the events_plot.json template misses the plot_len declaration, could you please give me the definition of this field? (reindexing with dynamic: strict fails with: "mapping set to strict, dynamic introduction of [plot_len] within [_doc] is not allowed )
I did change the replica setting on the same index yes, I reverted it back from 1 to 0 afterwards
I’ve set dynamic: “strict” in the template of the logs index and I was able to keep the same mapping after doing the reindex
Now I am trying to restart the cluster with docker-compose and specifying the last volume, how can I do that?
Is it safe to turn off replication while a reindex operation is happening? the reindexing is rather slow and I am wondering if turning of replication will speed up the process
I made sure before deleting the old index that the number of docs matched
Did you back up the data before your changes?
I see that I have several volumes:$ docker volume ls DRIVER VOLUME NAME local 5b0bfe5ab1a3d645bd635b2fb6f2aefd2b657d566019343c8305959903996c67 local 43b60287d60db798dc9d1defe1d7d861334c9c8299aefad6da2f20db278cfc5b local 1406d50aa65ab55d323500d1fb23f19adfc6e721261ab6103a59d20e82146099 local 7367a215bd42a4e888e5d88ce708bf74aedc48a6e9417c72a19739cb80f25e6d local 7413c39f5e4b6568304832d9d2e925ebdbf47ad31ad22d77830d3618af79237b local a55cb71edff48c2138a5da9d8d1e26df3b8454f9c3b1ac3b64692a4db5102600 local b6cd9aaeddb2113dda61585318dd031998cc5b8c4a4609470df62faf269713a3 local fd4bc62663c8560a7e59d6acb5bdda9e88e4659ac504af7477c144f105c284d4

Ok I have a very different problem now: I did the following to restart the ES cluster:docker-compose down docker-compose up -dAnd now the cluster is empty. I think docker simply created a new volume instead of reusing the previous one, which was always the case so far.
This one is indeed dynamic but can be set as follows: "plot_len":{"type":"long"}
I reindexed only the logs to a new index afterwards, I am now doing the same with the metrics since they cannot be displayed in the UI because of their wrong dynamic mappings
I'm not sure... what OS are you using? We're usually using volumes specifically mounted to EBS volumes
AppetizingMouse58 btw I had to delete the old logs index before creating the alias, otherwise ES won’t let me create an alias with the same name as an existing index
What ES version are you using? Maybe that's related?
Should I try to disable dynamic mapping before doing the reindex operation?
We can compare with the table that you sent yesterday. Unless a lot of new events were written since then
should I try to roll back to clearml-server 1.0.2? I am very anxious now…
the reindexing operation showed no error and copied everything
I’ve reindexed the data for the logs, now the mappings are correct but I am missing one month of data, I have literally no idea where this data is/how it disappeared
Not of the ES cluster, I only created a backup of the clearml-server instance disk, I didn’t think there could be a problem with ES…
Sorry, I have no real experience with docker-managed volumes 😞
Yes, it is safe to put number_of_replicas to 0 and refresh_interval to -1 for the target index before the reindex and then put them back after the reindex is finished
So it can be that when restarting the docker-compose, it used another volume, hence the loss of data
But you did change the replica setting - did you reindex?
Hi JitteryCoyote63 , are you still missing a month of data in the event logs? If you do cat indices do you see the same amount of docs in the original and the new ones?
