Inode size is not configurable

[Tytus Kurek]

It looks like at the moment the XFS inode size is not configurable, as it's hard-coded in charmhelpers:

https://github.com/juju/charm-helpers/blob/master/charmhelpers/contrib/storage/linux/utils.py#L113

As a result it is not possible to set the desired inode size when initializing the block devices for Swift.

It has been observed that with the default inode size of 1024 it is not possible to store 20M of containers on a cluster consisting of 6 storage nodes, each with 2 * 200 GB SSDs. The replication factor used was 4.

Tytus, there is a field which is indicating who is working on an issue "Assigned to". That one is used to avoid any waste of time by having several people working on it.

If in the future you want to report a bug and in addition work on it (which is great) please consider to mark yourself on it, or if you find somebody who has already indicated that is is going to work on it, don't compete with him, please communicate to him that you also plan to work on it or just avoid that, there are plenty of bugs not addressed :-)

Thanks,
s.

Sahid,

Thank you very much for your work on that. Apologies for not marking myself as an assignee.

Regards

Tytus
