We have some questions about the IO commands (
eos io ...) that might interest us. We can see already that some interesting output can be found for
eos io stat, but we would like to understand more about
eos io ns and
eos io reort ones :
- does calling these commands on a very large namespace (e.g. our one has 780M files and 162M folders) have impact on the performance, or can we use them freely and the output is returned immediately (even with
- what is the meaning of
eos io reportoutput ? On our test instance, even when doing some access, the output is always :
----------------------- SUMMARY ------------------- | avg. readd: 0.00 MB/s | avg. write: 0.00 MB/s | total read: 0 B | total write: 0 B | times read: 0 | times written: 0 |
even if :
# eos io enable -n error: IO report namespace already enabled
- is there a way to have in any case the usage of one part of the namespace (i.e.
/eos/instance/path/to/folder) for the period since the MGM start, even if by this we need to add it to a watch list ?
- Do you know if this output is used on some instance to keep some metrics about these values ?
