Receiving java.io.Exception: Input/output error

1

Good morning!

I’m receiving the following error when attempting to run dremio-admin clean -i (RocksDB reindexing job):

Failed to complete cleanup.
java.lang.RuntimeException: java.io.IOException: Input/output error
Suppressed: java.io.IOException: Input/output error
Caused by: java.io.IOException: Input/output error

@hmarchman-jones It looks like there is an IO error, can you please try “touch test” under /db/search?

I ran the following command in /db/search:

sudo -u dremio touch ./test

these are the results of ls -l in the directory afterward:

@hmarchman-jones Under the Dremio log folder there should be a log file generated for the clean command, can you please attach that

This is resolved.
I was running ./dremio-admin clean as root.
It works when running as user dremio.
You may want to update documentation to reflect this.

@hmarchman-jones Yes, it needs to be run as root. The error message is also not useful, will create tickets for both

Thanks for the update
