| * quota-enforcer: initialize enforcer rpc iff quota is enabledKrishnan Parthasarathi2013-09-242-8/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | Details: -------- In init, we should create an rpc only when quota is enabled on the volume. In reconfigure, we should reuse the enforcer rpc, if any, on enable. On disable, we should disable the enforcer rpc, if present.

|/ | | | | | | | | | | | | | | Commit makes the following changes to the source. i. Updating hard link count for parent dir should be configurable. Starts working only when the quota is enabled. ii. Heal nlinks of pgfid xattr in lookup. iii. Start quota crawler without readdirp optimization. iv. Rename: Handle the internal fops properly. Use GLUSTERFS_INTERNAL_FOP_KEY for representing the internal fops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code adjusts the statvfs values if the quota-deem-statfs option is enabled. i. Adjust statvfs based on limit configured on root. ii. If limit is set on the inode passed, use size/limits on that inode to populate statvfs. Otherwise, use size/limits configured on root. iii. Upon statvfs, update the ctx->size on the inode. iv. Don't let DHT aggregate, instead take the maximum of the usages from the subvols of the DHT, since each of it contains the complete information.

* | features/quota: Pass correct delta during quota_updationRaghavendra G2013-09-031-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to calculate delta as, delta = (postbuf->ia_blocks - prebuf->ia_blocks) * 512; However this can result in some blocks getting accounted twice in a multithreaded environment. This is because at storage/posix, we dont do, * stat (file, &prebuf) * write () * stat (file, &postbuf) as a single atomic operation. So, stat in step 3, can account for some blocks which are allocated as part of a parallel write. One of the possible fixes is to make these three operations by holding a lock. However, this is too costly operation and hence quota relies on size of the vector being written (with the check that if post and pre block count are same, entire write was accomodated in existing blocks). This seems to be acceptable since we don't solely rely on size_updation by quota-enforcer (we do fetch aggregated size from quotad after a timeout).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A getxattr on key GET_ANCESTRY_DENTRY_KEY to storage/posix would return a list of direntries which can be used to construct inode contexts of individual translators. The result of getxattr on this key can be viewed as similar to readdirp_cbk with the difference that the dentries returned here represent various paths from that inode till root rather than the children of a directory. This patch also modifies marker/quota and enforcer to utilize this key. Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Change-Id: I7132e7d56f2fac0f8749f51227d9f2ef27f9d354 BUG: 969461
