OSS Versions

See Third-Party Components for Storage 15.2.0 for the complete listing of packages and versions for this release.

Fixed in 15.2

  • Restarting

    behavior —

    Behavior: Improved the behavior of restarting internal processes on failure, reducing the need for manual node restarts. (SWAR-9670)

  • Cluster

    performance —

    Performance: Reduced disk utilization when feeds are in use, possibly improving cluster performance. (SWAR-9659)

  • Skylake

    perf vulnerability detection —

    Perf Vulnerability Detection: Improved the detection of CPUs that might be impacted by a kernel-level performance vulnerability. (SWAR-9485)

  • Multi-

    version deletion —

    Version Deletion: Fixed an issue where rapid deletes of multiple versions of the same object sometimes leave an Elasticsearch record for the removed object. (SWAR-9625)

  • Performance

    : Improved the GET performance; it is 10% better than the previous release (15.1.0). (SWAR-9660)

Watch Items and Known Issues

The following watch items are known:

...

  • The Storage UI shows no NFS config if the Elasticsearch cluster is wiped. Contact DataCore Support for help in repopulating the SwarmFS config information. (SWAR-8007)

  • Any incomplete multipart upload into a bucket leaves the parts (unnamed streams) in the domain if a bucket is deleted. To find and delete those parts, use the s3cmd utility (search the Support site for "s3cmd" guidance). (SWAR-7690)

  • The chassis shuts down but does not come back up when restarting a cluster of virtual machines that are UEFI-booted (versus legacy BIOS). (SWAR-8054)

  • Invalid config parameters that prevent the unassigned nodes from booting are created if subcluster assignments are removed in the CSN UI. (SWAR-7675)

  • On node reboots, some feed statistics that are not persisted across boots may show up incorrectly. It will fix itself eventually. Currently, there is no workaround for this. (SWAR-9720)

To upgrade Swarm 9 or higher, proceed to How to Upgrade Swarm. For migration from Swarm 8.x or earlier, contact DataCore Support for guidance.

Instructions for rpm v15.2 and above on CSN

The user must follow the below steps if using rpm version 15.2 or above on the CSN:

  1. Edit /etc/caringo/netboot/netboot.cfg file on the CSN.

  2. Verify that KernelOptions parameter includes the new max size for the ramdisk.

    Code Block
    kernelOptions = castor_net=active-backup: ramdisk_size=190000

    Use space separater separator between “active-backup:” and ramdisk_size=190000 as used in above command.

  3. restart netboot.
    service netboot restart
