Doc Text:	Previously, Heketi created a 32GB volume to store the heketi db file, which was much more than the average requirement. With this release, the size of the volume is been reduced to 2GB. This does not change the volume size of existing setups and is applicable only for new setups.	Story Points:	---

Description Prasanth 2016-12-21 06:47:48 UTC

Description of problem:

Reduce the default size of "heketidbstorage" volume from 32GB to a more reasonable lower size. At present when heketi is deployed, it automatically creates a volume of 32GB for storing it's database. This can't be changed by the users based on their setup as it's not a configurable value. See below:

#######
Name: heketidbstorage
Size: 32
Volume Id: cd26a3b5462c8f689c74797571864a0c
Cluster Id: c5584c85e7b96a5895842a1dd4712c23
Mount: 10.70.46.3:heketidbstorage
Mount Options: backup-volfile-servers=10.70.46.54,10.70.46.6
Durability Type: replicate
Distributed+Replica: 3
#######

Since the min required size is 32GB, it cannot be even tested in certain automated test environments which has lower disk size as the setup itself will fail. Moreover, in most of the test setups the size of the heketidb was mostly seen as around 10/20MB or even lower. So I strongly believe that we should either lower the default size to a more appropriate value or provide a configurable option for the user instead of hard-coding it.

Version-Release number of selected component (if applicable):
heketi-cli 3.1.0

How reproducible: 100%

Hi Humble,

I have made minor edits to the doc text to be included in the errata. Let me know if it looks ok and sign off if you have no review comments.

Thanks
