Shyamsundar 2020-09-11 12:04:15 UTC Doc Text Cause: Creating large number (greater than 400) of subvolume snapshots, across subvolumes

Consequence: Slows down filesystem operations

Fix: Setup subvolumes to only support snapshots at subvolume root directory and preventing cross subvolume links and renames, thus improving performance at snapshot scale

Result: Creating higher count of subvolume snapshots across subvolumes, does not degrade filesystem operations performance as in previous releases

Aron Gunn 2020-09-11 18:15:31 UTC Doc Text Cause: Creating large number (greater than 400) of subvolume snapshots, across subvolumes

Consequence: Slows down filesystem operations

Fix: Setup subvolumes to only support snapshots at subvolume root directory and preventing cross subvolume links and renames, thus improving performance at snapshot scale

Result: Creating higher count of subvolume snapshots across subvolumes, does not degrade filesystem operations performance as in previous releases
.Improved Ceph File System performance as the number of subvolume snapshots increases

Previously, creating more than 400 subvolume snapshots was degrading the Ceph File System performance by slowing down file system operations. With this release, you can configure subvolumes to only support subvolume snapshots at the subvolume root directory, and you can prevent cross-subvolume links and renames. Doing this allows for the creation of higher numbers of subvolume snapshots, and does not degrade the Ceph File System performance.
