From b054985d2f7db9ab72759c988db11feb855a1b5e Mon Sep 17 00:00:00 2001 From: vmallika Date: Thu, 30 Apr 2015 16:50:47 +0530 Subject: quota/marker: turn off inode quotas by default inode quota is a new feature implemented in glusterfs-3.7 if quota is enabled in the older version and is upgraded to a new version, we can hit setxattr spike during self-heal of inode quotas. So, when a quota is enabled, turn off inode-quotas with a xlator option. With this patch, we still account for inode quotas but only when a write operation is performed for a particular file. User will be able to query inode quotas once the Inode-quota xlator option is enabled.
