Description Anoop 2016-06-15 13:23:34 UTC
Need to put a check in heketi to ensure that only 14 snapshots are allowed on a volume.

Comment 2 Luis Pabón 2016-06-15 21:03:56 UTC
This cannot be done in Heketi. It does not have a snapshot API.

Comment 3 Luis Pabón 2016-06-15 21:07:47 UTC
I think this is instead going to be done with Documentation.  But are you asking for Heketi not to check, but instead send the following command:

gluster snapshot config [vol-name] [<snap-max-limit> <count>] [<snap-max-soft-limit> <percentage>] [force] 

Which sets the limit?

Comment 8 Luis Pabón 2016-07-07 02:45:41 UTC

Comment 11 Bala Konda Reddy M 2016-07-22 09:32:51 UTC
Restricted the snapshots limit to 14 on a particular volume using the following command

gluster snapshot config [vol-name] [<snap-max-limit> <count>] [<snap-max-soft-limit> <percentage>] [force] 

[root@dhcp37-163 ~]# heketi-cli --version
heketi-cli 2.0.6

Once the soft limit reached throws the warning message like in the below

sh-4.2# gluster snapshot create snaplimit_13 vol_e7d26963ac1d4ecaa02f76b2c13ae>
snapshot create: success: Snap snaplimit_13_GMT-2016.07.22-00.41.07 created successfully
Warning: Soft-limit of volume (vol_e7d26963ac1d4ecaa02f76b2c13ae23a) is reached. Snapshot creation is not possible once hard-limit is reached.

sh-4.2# gluster snapshot create snaplimit_14 vol_e7d26963ac1d4ecaa02f76b2c13ae>
snapshot create: success: Snap snaplimit_14_GMT-2016.07.22-00.41.27 created successfully
Warning: Soft-limit of volume (vol_e7d26963ac1d4ecaa02f76b2c13ae23a) is reached. Snapshot creation is not possible once hard-limit is reached.

After 14 snapshots, tried to create another snapshot then it throws the following error

sh-4.2# gluster snapshot create snaplimit_15 vol_e7d26963ac1d4ecaa02f76b2c13ae>

snapshot create: failed: The number of existing snaps has reached the effective maximum limit of 14, for the volume (vol_e7d26963ac1d4ecaa02f76b2c13ae23a). Please delete few snapshots before taking further snapshots.
Snapshot command failed

Hence Marking it as Verfied

How to set the snapshot limit from heketi

Comment 13 Luis Pabón 2016-07-24 05:42:15 UTC
It is set by Heketi automatically.  Issue is that the deploy-heketi template does not have the environment variable setting as the heketi template.

Heketi template:

Deploy-heketi needs this setting also because it will allow the initial nodes added to the system to have 14 max snapshots.

Comment 14 Bala Konda Reddy M 2016-07-24 06:28:24 UTC
1.heketi-cli topology load --json=topology.json
2.Created a volume
3.To check the snapshot limit 
[root@dhcp37-163 ~]# oc rsh 
sh-4.2# gluster snapshot config

Snapshot System Configuration:
snap-max-hard-limit : 256
snap-max-soft-limit : 90%
auto-delete : disable
activate-on-create : disable

Snapshot Volume Configuration:

Volume : heketidbstorage
snap-max-hard-limit : 256
Effective snap-max-hard-limit : 256
Effective snap-max-soft-limit : 230 (90%)

Volume : vol_8ee1cf4949dee37252dd9e88e99fa2a8
snap-max-hard-limit : 256
Effective snap-max-hard-limit : 256
Effective snap-max-soft-limit : 230 (90%)
sh-4.2# exit

Actual :
SNAPSHOT LIMIT is set in heketi template but it is not taking the configuration while loading the topology and still able to take more than 14 snapshots for a particular volume . In deploy-heketi template No snapshot limit is not set to 14.

Expected : Snapshots limit should 14 per volume in aplo. After 14 snapshot it should throw error like the limit is 14 only.
