PetaSAN 2.3 released !

Happy to  announce the release of PetaSAN 2.3 with following features:
  • Async Replication across different clusters. Snapshot diffs are replicated according to user defined schedules. Please refer to Replication Guide.
  • Adjust Backfill/Recovery Speed.
  • Include Journal disks in Cluster Benchmark.
  • Check empty partition space on Journals before selection.
  • Ceph Luminous version 12.2.12.

Take a look at our new cool screenshots

Note: Memory requirements are now 4 GB per OSD based on new Ceph recommendations. For upgrades, this value will be lowered to 2 GB so not to impact existing systems, it can be increased manually later via the osd_memory_target config parameter on systems that have enough memory. New installs will be configured to use 4 GB per OSD with the exception of choosing the "Entry Level Hardware" profile which will use 1 GB.

Great news!

Thanks for the new Release.

One question, please, can you provide a procedure to increase manually "osd_memory_target" on updated systems?

I suppose that we need to change value on /etc/ceph/[CLUSTERNAME]-petasan.conf and run systemctl restart ceph, is that correct way?

Regards

Andoni

Yes you need to edit it in the config file.

you can then restart or do a

ceph tell osd.* injectargs '--osd_memory_target=4294967296' --cluster XX

you can check the current settings on an OSD via:

ceph daemon osd.XX config get osd_memory_target --cluster XX
