Re: size of journal partitions pretty small

[Paul Emmerich <paul.emmerich@xxxxxxxx>]

1) yes, 5 GB is the default. You can control this with the 'osd journal size' option during creation. (Or partition the disk manually)

2) no, well, maybe a little bit in weird edge cases with tuned configs but that's rarely advisable.

But using Bluestore instead of Filestore might help with the performance.

 I installed my OSDs using ceph-disk.  The journals are SSDs and are 1TB.  I notice that Ceph has only dedicated 5GB each to the four OSDs that use the journal.

 1) Is this normal

 2) Would performance increase if I made the partitions bigger?

 Thank you
