Description krishnaram Karthick 2018-03-07 16:09:32 UTC

Description of problem:

With blockhosting volume of size 100 GB, blockvolume create of size >100Gb fails with a vague error message.

# heketi-cli blockvolume create --size=120 Error: Unable to execute command on glusterfs-storage-pgbjn:
# oc rsh heketi-storage-1-xznlb
sh-4.2# rpm -qa | grep 'heketi'
heketi-client-6.0.0-5.el7rhgs.x86_64
python-heketi-6.0.0-5.el7rhgs.x86_64
heketi-6.0.0-5.el7rhgs.x86_64
sh-4.2# 



This was not the case in CNS 3.6,

# rpm -qa | grep 'heketi'
heketi-client-5.0.0-19.el7rhgs.x86_64
# heketi-cli blockvolume create --size=600
Error: Default Block Hosting Volume size is less than block volume requested.
# oc rsh heketi-1-dm835 
sh-4.2# rpm -qa | grep 'heketi'
heketi-client-5.0.0-19.el7rhgs.x86_64
python-heketi-5.0.0-19.el7rhgs.x86_64
heketi-5.0.0-19.el7rhgs.x86_64
sh-4.2# 

Hence, this is a regression

Version-Release number of selected component (if applicable):
Heketi 6.0.0

How reproducible:
Always

Steps to Reproduce:
1. create a blockhosting volume of size 100Gb
2. Try to create a block device of size > 100Gb


Actual results:
create request fails with error 'Error: Unable to execute command on glusterfs-storage-pgbjn:

Expected results:
proper error message as seen in CNS 3.6

Additional info:
heketi logs shall be attached.

Comment 13 krishnaram Karthick 2018-03-14 04:41:54 UTC

This issue is fixed in build - heketi-6.0.0-7.el7rhgs

A proper error message is now presented to the user.

[root@dhcp46-101 ~]# heketi-cli blockvolume create --size=400
Error: Failed to allocate new block volume: The size configured for automatic creation of block hosting volumes (100) is too small to host the requested block volume of size 400. Please create a sufficiently large block hosting volume manually.
