to see integrated monitoring of (thin) LVs and some form of acting on
crucial events. One idea would be to make the Gluster Volume read-only
when it detects that a brick is almost out-of-space. This is close to
what local filesystems do when their block-device is having issues.
For the oVirt-Gluster integration, where gluster volumes are managed and consumed as VM image store by oVirt - a feature was added to monitor and report guaranteed capacity for bricks as opposed to the reported size when created on thin-provisioned LVs/vdo devices. The feature page provide some details - https://ovirt.org/develop/release-management/features/gluster/gluster-multiple-bricks-per-storage/. Also, adding Denis, the feature owner.
Sorry for the necroposting, but i would like to inform you, that monitoring of physically available (guaranteed) free space is implemented.
