Release Notes

v0.7.1

• Correction: one “orphaned” device-mapper device without a disk no longer stops BlockDevice detection on the entire node - previously, because of it, the agent did not create a single BlockDevice on the node, including healthy disks
• Correction: LVMVolumeGroup with a single PV whose name could not be determined immediately no longer hangs in Pending forever - empty status.nodes post and no retry in the absence of udev events have been fixed
• Correction: the agent substitutes the serial number inherited from the parent device if direct reading of the serial number fails (multipath participants, crypt/dm devices) - previously such devices were skipped when detecting BlockDevice
• Optional resources (VerticalPodAutoscaler, PodMonitor/ServiceMonitor) are now enabled based on the presence of a CRD in the API, and not based on the enabledModules list
• Documentation: fixed duplication of the description key in the Russian CRD LVMVolumeGroup, which broke docs-builder, added the missing status.extentSize description and restored the blockDevice description

v0.7.0

• Correction: the agent no longer accepts LVM structures inside block devices given to virtual machines as its own - the /dev/loop exception was returned in the LVM global_filter. Fixed the resulting LVMVolumeGroup failures with CacheEmpty and ScanFailed causes - the VG name is no longer considered an identifier, and the LVM warning about a duplicate of someone else’s name is not attributed to our group
• Added support for LVM on files: spec.fileDevices field of LVMVolumeGroup and LVMVolumeGroupSet. The agent creates a file, connects it as a loop device and uses it as a PV, which gives LVM storage on a node without a free disk; the blockDeviceSelector field has become optional
• The scheduler (scheduler-extender) takes into account the PVCs listed in the extra-pvcs pod annotation
• LVMLogicalVolume, LVMLogicalVolumeSnapshot and LVMVolumeGroupSet publish status.conditions; BlockDevice now has a Consumable condition, explaining why the device cannot be used; processing of LVMVolumeGroup conditions has been brought to a general form
• Correction: a volume created from a snapshot or clone is expanded to the requested size - previously the PVC remained in Pending waiting for a size that never appeared
• Correction: thin pool set by percentage of VG size no longer gets stuck at VGConfigurationApplied=False due to LVM rounding by one extent
• Correction: an idle call to lvextend is recognized as harmless on LVM 2.03.16 - otherwise LVMVolumeGroup remained in NotReady
• Correction: when taking control of an existing VG, blockDeviceSelector no longer remains empty
• Correction: after pvcreate and vgcreate the agent calls udevadm to update the udev database
• Correction: when storage-foundation is enabled, the agent loads the dm_snapshot kernel module
• Removed outdated CRD LvmVolumeGroupBackup, left over from a one-time migration: the new hook removes finalizers from leftovers and removes the CRD itself
• Added an experimental mode for detecting block devices via netlink, enabled by the ENABLE_NETLINK_BLOCK_DEVICE_DISCOVERY flag
• Updating base images to v1.3.25, Go 1.26.5 and lib-helm to 1.72.13
• Fixed vulnerabilities in golang.org/x/net, golang.org/x/sys and golang.org/x/crypto
• Internal changes in module assembly and CI, the set of e2e tests has been significantly expanded

v0.6.10

• The general accept rule was removed from LVM global_filter, which led to scanning of non-standard paths (/dev/disk/by-diskseq/*) and duplication of VG names

v0.6.9

• The agent now ignores “foreign” block devices (rbd, drbd, nbd, loop) when scanning LVM
• Fixed handling of duplicate VG names: LVMVolumeGroup status is no longer corrupted
• The blocking of the agent pod launch has been eliminated; added timeouts for LVM commands
• Improved stability of legacy block device names: matching by serial number or WWN prevents re-creation when name changes
• Fixed BlockDevice selector validation: the In operator is now the only valid one

v0.6.8

• Fixed race in scheduler-extender when PVC.Status.Phase is empty: PVC binding decision is now made based on Spec.VolumeName, nodes without a suitable LVMVolumeGroup are always rejected
• Agent is now also scheduled on sds-elastic data nodes
• Updating base images and lib-helm to 1.72.0
