-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I'll take a stab at this. I don't think it will be a feature that you will find in Ceph due to the fact that Ceph doesn't really understand what is going on inside the RBD. There are too many technologies that can use RBD that it is not feasible to try and support something like this. You can however have a service that runs in your VM which monitors free space. Then the free space gets too low, it can call to a service you write which will then expand the RBD on the fly and then the VM itself and resize the partitions and the file system after the RBD is expanded. I'm not sure how CephFS fits into all of this as it is different than RBD. CephFS is to NFS as RBD is to SAN block storage. If I misunderstood the question, please clarify. -----BEGIN PGP SIGNATURE----- Version: Mailvelope v0.13.1 Comment: https://www.mailvelope.com wsFcBAEBCAAQBQJVunUCCRDmVDuy+mK58QAAwGcP/0Y5gz4flZ0XuaXdKlez iogX9QsAoPk9s8fd0vpc3Prlhx/YODgkqqm35iJh5PaDEqb6njZwe3CR0WBh mba6xAjSGe9D8dzkLP5cCvRSlkVexddAfj5K/M+JkjWyQhlq4TQcu3CSBo8Q 1pyI6dDwWNl8ScCu4/PN4Bl2OD9favEs8tXjNJ5/mhZWFjSN7t8/LLqsUNu6 AlMp2hFFfb1f0ky7EI/Hg3uw0+BbGDn/N0oxDyZqH7Wqnp/5L4kRAkZkXsGh T7a4KxReNu/5eg2Tef83h7AAeRTSDTEw+38ToGnOIGpXYCxKdWF878Xs7tVa +jPUds7aSNazaRB9nSPYiIxXBcTRKN2VFqhFNyQ/6CrEvsjkZQKkQfjJgNtL eg0hmjS1X0QryapX7xhfz+Apx369Pkitm8UosyPIwEPnMuVqwVN5VwDTDkub FlGNHX+b1/NDgZDpWF+b5gOErHMW8kWRNt/+2i5pXj0ZjDADmrQn+Hd9G0Hx g1dot64vLogcvcyt0C+fLicF9xlddU/Zuz7VZLyIOH1KSVhABK1RaI8+Zws6 ZWriDFal0ztd0BNEQlCqtlo4hyY/AVies9qB6V4sUL0UuEL/+iTj71/VNh09 RJIURK6KySwxtW97pMGGafw5xPOjpxnm75D6AmovZ6WV68GSxlNpTY/V7CPH dW/U =h5n5 -----END PGP SIGNATURE----- ---------------- Robert LeBlanc PGP Fingerprint 79A2 9CA4 6CC4 45DD A904 C70E E654 3BB2 FA62 B9F1 On Wed, Jul 29, 2015 at 11:32 PM, Shneur Zalman Mattern <shzama@xxxxxxxxxxxx> wrote: > Hi to all! > > > Perhaps, somebody already thought about, but my Googling had no results. > > > How can I do RBD that will grow on demand of VM/client disk space. > > Are there in Ceph some options for this? > > Is it planned to do? > > Is it utopic idea? > > Is this client need CephFS already? > > > Thanks, > > Shneur > > > > > > ************************************************************************************ > This footnote confirms that this email message has been scanned by > PineApp Mail-SeCure for the presence of malicious code, vandals & computer > viruses. > ************************************************************************************ > > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
