From 6f389fbb812b384bdd9bf4a20e86930505531996 Mon Sep 17 00:00:00 2001 From: Krutika Dhananjay Date: Fri, 21 Nov 2014 11:47:23 +0530 Subject: features/shard: Introducing sharding translator Based on the high-level design by Anand V. Avati which can be found @ https://gist.github.com/avati/af04f1030dcf52e16535#sharding-xlator-stripe-20 Still to-do: * complete implementation of inode write fops - [f]truncate, zerofill, fallocate, discard * introduce transaction mechanism in inode write fops * complete readv * Handle open with O_TRUNC * Handle unlinking of all shards during unlink/rename * Compute total ia_size and ia_blocks in lookup, readdirp, etc * wind fsync/flush on all shards Note: Most of the items above are related. Once we come up with a clean way to determine the last shard/shard count for a file/file size and the mgmt of sparse regions of the file, implementing them becomes trivial.
