| deletion.gcInterval |
The interval of cleaning failed volumes or snapshots that fail to
be deleted from a Shared Block primary storage. Default: 3600. Unit:
second. |

[1,+∞) |
| qcow2.allocation |
The policy used to allocate space for volumes in Shared Block
primary storages. Default: metadata. Valid values: none and
metadata. |

| qcow2.cluster.size |
The cluster size of QCOW files in a Shared Block primary storage.
Default: 2097152. Unit: byte. Valid values: 512 to 2097152. |
2097152 |
[512,2097152] |
| fail.if.multipath.no.path |
Specifies whether to disable the queue_if_no_path feature for
multipath devices. Default: true. This value indicates that if no
path of the multi-path devices used by SharedBlock primary storages
is active, I/O requests fail. If set to false, the heartbeat
detection and recovery mechanisms may not work as expected. Please
proceed with caution. |
true |
|
| thin.provisioning.initialize.size |
The initial size of thin-provisioned volumes. Default:
5368709120. Unit: byte. The initial size cannot be lower than
1073741824 bytes. |
5 GB |
[1073741824,+∞) |
| thin.provisioning.volume.utilization.percent |
The maximum usage ratio of thin-provisioned volumes. Default: 85.
Unit: %. If the actual usage ratio of a thin-provisioned volume is
higher than the maximum usage ratio, the volume will automatically
scale up based on the Auto Scaleup Size of Thin-Provisioned Volume
setting. |
85 |
[1,+∞) |
| thin.provisioning.volume.freespace |
The minimum space that must be available for thin-provisioned
volumes. Default: 5368709120. Unit: byte. If the difference between
the actual size of a thin-provisioned volume and the used storage
space is lower than the minimum available space, the volume will
automatically scale up based on the Auto Scaleup Size of
Thin-Provisioned Volume setting. |
5 GB |
[1073741824,+∞) |
| thin.provisioning.volume.increment |
The auto scaleup size of thin-provisioned volumes. Default:
5368709120. Unit: byte. |
5 GB |
[1073741824,+∞) |
| enable.lvmetad |
Specifies whether to enable the lvmetad service. Default: false.
If set to true, operations on Shared Block primary storages will be
accelerated. Please note that you need to enable the service in a
proper way. Otherwise, metadata may be damaged. |
false |
|
| heartbeat.io.timeout |
The timeout period of inspecting the heartbeats of Shared Block
primary storages. Default: 20. Unit: second. If the inspection times
out for ten consecutive times, heartbeat inspection fails. |
20 |
[1,+∞) |
| snapshot.shrink |
Specifies whether to enable the snapshot shrinking feature.
Default: true. This value indicates that you can shrink the used
storage space of snapshots in thick-provisioned root volumes and
data volumes in a Shared Block primary storage. |
true |
|
| max.actual.size.factor |
The maximum rate between the actual size and virtual size of
thin-provisioned volumes. Default: 3. Please proceed with
caution. |
3 |

| device.allocate.strategy |
- The policy used to distribute a SharedBlock LUN to a volume
and snapshot. Valid values: none (default), minLvCounts, and
maxFreeSize.
- If you select maxFreeSize, when you create a volume or
snapshot, the SharedBlock LUN that has the the most
available space is distributed to the volume or
snapshot.
- If you select minLvCounts, when you create a volume or
snapshot, the SharedBlock LUN that has the smallest total
number of volumes and snapshots and has sufficient available
space is distributed to the volume or snapshot.
- If you select none, when you create a volume or snapshot,
when you create a volume or snapshot, a SharedBlock LUN that
has sufficient spaceis is distributed to the volume or
snapshot based on the system scheduling.
- If you have already set the LUN distribution policy
specifically for a SharedBlock primary storage, this global
setting does not take effect on the primary storage.
