Change Summary

Replicated Storage (Mayastor)

Allow labels containing slashes (e.g. Kubernetes-style domain/key labels) in the delete, cordon and drain REST routes (https://github.com/openebs/mayastor-control-plane/pull/1183)
Fix Loki auto-discovery timeout during support bundle collection and raise the default --timeout (https://github.com/openebs/mayastor-extensions/pull/1010)
kubectl mayastor plugin output now includes an ID column and spurious error strings have been silenced (https://github.com/openebs/mayastor-extensions/pull/1036)

Refer to the Mayastor v2.12.1 release notes for detailed changes.

Local Storage

LVM

Add a --default-format-options node agent argument (lvmNode.defaultFormatOptions in the Helm chart) to set node-level default mkfs options per filesystem, used when a StorageClass does not set formatOptions (https://github.com/openebs/lvm-localpv/pull/506)

Note for users on older kernels: mkfs.xfs 6.5+ enables the nrext64 feature by default, which only kernel 5.19+ can mount. On clusters with older kernels, set lvmNode.defaultFormatOptions.xfs: "-i nrext64=0" (or the per-StorageClass formatOptions) to keep XFS volumes mountable.

ZFS

Add a formatOptions StorageClass parameter for extra mkfs options on first format, and a --default-format-options node agent flag (zfsNode.defaultFormatOptions in the Helm chart) for per-filesystem defaults; ignored when fstype is zfs (https://github.com/openebs/zfs-localpv/pull/760)
Go module path moved to github.com/openebs/zfs-localpv/v2 for semantic import versioning; affects only Go library consumers (https://github.com/openebs/zfs-localpv/pull/756)

The same older-kernel note as LVM above applies; set zfsNode.defaultFormatOptions.xfs: "-i nrext64=0" if any node runs a kernel older than 5.19.

Rawfile

Add support for setting compute resources on the API Server (https://github.com/openebs/rawfile-localpv/pull/399)
Fix StorageClass copyOnWrite with value "" to correctly default to auto-detected instead of false (https://github.com/openebs/rawfile-localpv/pull/404)
Fix controller deployment not being disableable due to an incorrect Helm variable (https://github.com/openebs/rawfile-localpv/pull/409)
StorageClass and VolumeSnapshotClass are now updatable via helm upgrade
Add documentation for async volume replication with VolSync
