Release 19.3, more details here.

19.3 revision 19.01.2592.cf99471bd

Released 25 Dec 2021

    • modules tainted state from /proc

    • free space on all filesystems

    • lshw json output

    • lspci with kernel modules output

  • storpool_ctl:

    • just warns when the storpool_bd module could not be reloaded

    • the status option now shows all alerts for kernel module versions

  • storpool_server:

    • resets wbt_lat_usec parameter in /sys to 0 for all StorPool data disks

19.3 revision 19.01.2401.48d842f1d

Released 29 Sep 2021

  • Improved handling of large volume and volume/snapshot chains

    The internal metadata structure is updated for more efficient metadata operations. The upgrade will provide:

    • Significantly improved flexibility for clusters with a large number of volumes/snapshots and chains of volumes or snapshots with sizes larger than 1TiB.

    • Better overall relocator performance.

    • More efficient object use for large snapshots.

    • Improved overall snapshot delete cycle.

    StorPool support team handles the upgrade to meta V2. The upgrade is in the internal data structures, and will be enabled once all services in the cluster are running the latest version.

    Once upgraded, the size of the disks sets table can be updated for each volume (or snapshot) to up to 32K. For example, a very large volume filled with data can be updated to a larger disk sets table size, providing more granularity when re-balancing its data. This set of features will be very helpful when a cluster has a small set of disks (the usual for a backup only cluster) or disks with different sizes, typical for clusters in process of expansion or hardware being upgraded/replaced.

    Note

    Note that expansions of the volume/snapshot disk table with a larger size will require a re-balancing operation, though shrinking will be applied immediately by the relocator.

    There are few small changes in the output for some commands after the upgrade to meta V2 is completed, for example, the storpool task list command output will now flag all operations related to a change in the volume or snapshot policy with balancer (example output in 12.19.  Tasks).

  • Adds fix for storpool_stat service to properly cleanup processes after data collection (no leftover zombie processes).

  • Adds support for up to 16 server instances per node for high-performance use cases.

  • Fix for extending active maintenance.
