Re: How to set bluestore_rocksdb_options_annex

You should use 'ceph daemon osd.3 config get bluestore_rocksdb_options_annex' to verify config has been altered.


This option is treated as independent one and doesn't modify any other Ceph(!) option.

bluestore_rocksdb_options + bluestore_rocksdb_options_annex form a single RocksDB options list with options from *_annex being the last in that list and hence being effective.

Also it would be great if someone could give a hint on how to validate that this is really set for an osd...

As

Ceph daemon osd.3 config get bluestore_rocksdb_options

Still shows the default line without my modifications via the ...annex option

Best regards

For the records i have tried/done this like:

Ceph config set osd bluestore_rocksdb_options_annex option1=8,option2=4

But i am not sure if it is necessary to restart the osds... cause

Ceph config dump

Shows

... .. .
Osd advanced option1=8,option2=4 *
... .. .

The "*" is shown in the "RO" field..

Any Suggestions?

Thanks Mehmet

Hello Anthony,

it was introduced in octopus 15.2.10
See:  https://docs.ceph.com/en/latest/releases/octopus/

Do you know how you would set it in pacific? :)
Guess, there shouldnt be much difference...

Thank you
Mehmet

I think that’s new with Pacific.

Hello,

I have an octopus cluster and want to change some values - but i
cannot find any documentation on how to set values(multiple) with
bluestore_rocksdb_options_annex

Could someone give me some examples.
I would like to do this like ceph config set ...

Thanks in advice
Mehmet
