Doc Text: |
The POSIX translator is now enhanced with an option that allows user to reserve disk space on the bricks. Some administrative operations, like expanding storage or rebalancing data across nodes, require spare working space on the disk. The storage.reserve option lets users expand disk or cluster when backend bricks are full preventing ENOSPC errors on mount points.

Patch is posted on upstream https://review.gluster.org/#/c/17780/ Verified this RFE on glusterfs version: 3.12.2-5.el7rhgs.x86_64 1) Able to set/reset storage.reserve volume set option. 2) Reserved the space to 50% and created files using dd created files. Once the backend bricks reached the reserved space, file creation is failing with ENOSPC errors. I have filed below BZs while testing this RFE, https://bugzilla.redhat.com/show_bug.cgi?id=1554291 https://bugzilla.redhat.com/show_bug.cgi?id=1550991 https://bugzilla.redhat.com/show_bug.cgi?id=1550982 https://bugzilla.redhat.com/show_bug.cgi?id=1554298 Moving this BZ to Verified considering the basic functional is working and have bugs filed for the seen issues. Will file new BZs on this feature if seen during our regression testing.
