Old approach:
This is based on the path. So, the config file stored as limit-set key value
pair in the volfile was the source of truth for any directory to be enforced
the quota limit. So, we were storing it in a list and everypath is compared
with the list. This hinders scaling with the order of kilos of quota
directories. This approach is different from the XFS where the below method of
inode based limit is employed this adds the admins to learn new stuff.
New approach:
This is based on the inode. After the path is set with the quota limit. The
limit sticks with the inode. So, we need not to store the paths in the xlator
context/options, instead get the xattrs in the lookup. Set the hard and soft
limits of context from there.
The additional change in the glusterd to set the xattrs when limit-usage
command issued will be submitted as a separate patch.
This patch also does:
* Move the logging from the quotad to quota-enforcer.
* Save the soft limit in the context.
* Some clean up in quota-enforcer

Old implementation
* Client side implementation of quota
- Not secure
- Increased traffic in updating the ctx
New Implementation
* 2 stages of quota implementation is done: Soft and hard quota
Upon reaching soft quota limit on the directory it logs/alerts in the quota
daemon log (ie DEFAULT_LOG_DIR/quotad.log) and no more writes allowed after
hard quota limit. After reaching the soft-limit the daemon alerts the
user/admin repeatively for every 'alert-time', which is configurable.
* Quota is moved to server-side.
There will be 2 quota xlators
i. Quota Server
It takes care of the enforcing the quota and maintains the context
specific to the brick. Since this doesn't have the complete picture of
the cluster, cluster wide usage is updated from the quota daemon. This
updated context is saved and used for the enforcement.
It updates its context by searching the QUOTA_UPDATE_KEY from the dict
in the setxattr call, and is updated from nowhere else.
The quota is always loaded in the server graph and is by passed if the
feature is not enabled.
Options specific to quota-server:
server-quota - Specifies whether the features is on/off. It is used
to by pass the quota if turned off.
deem-statfs - If set to on, it takes quota limits into
consideration while estimating fs size. (df command)
ii. Quota Daemon
This is the new xlator introduced with this patch. Its the
*gluster client* process with no mount point, started upon enabling
quota or restarting the volume. This is a single process for all the
volumes in the cluster. Its volfile stored in
GLUSTERD_DEFAULT_WORKI_DIR/quotad/quotad.vol.
It queries for the sizes on all the bricks, aggregates the size and
sends back the updated size, periodically. The timeout between
successive updation is configurable and typically/by default more for
below-soft-quota usage and less for above-soft-quota usage. It
maintains the timeout inside the limit structure based on the usage;
below soft limit and above soft limit.
There will be thread running per volume which iterates through the list
and decides whether the size to be queried in the current iteration
based on its timeout. It takes the next iteration time taking the least
of the timeouts in the list of entries.
Maintains a separate inode table for each volume in the quotad. In the
first iteration it builds the table for quota-dirs (dirs on which limit
is set) and its components.
Options specific to quotad:
hard-timeout - Timeout for updation of usage to the quota-server
when the usage is crosses the soft-limit.
soft-timeout - Timeout for the updation of usage to the
quota-server when the usage is below soft-limit.
alert-time - Frequency of logging after the usage reached
soft limit.
Options common to both:
default-soft-limit - This is used when individual paths are not
configured with soft-limit and default value of
this option is 90% of the hard-limit.
limit-set - String containing all the limits.
Thus in the current implementation we'll have 2 quota xlators: one in server
graph and one in trusted client (quota daemon) of which the sole
purpose will be to aggregate the quota size xattrs from all the bricks and
send the same to server quota xlator.
* Changes in glusterd and CLI
A single volfile is created for all the volumes, similar to nfs volfile.
All files related to quota client (volfile, pid etc) are stored in
GLUSTERD_DEFAULT_WORK_DIR/quotad/.
The new pattern of the quota limit stores in
limit-set = <single-dir-limit>[,<single-dir-limit>]
single-dir-limit = <abs-path>:<hard-limit>[:<soft-limit-in-percent>]
It also introduces new options:
volume quota <VOLNAME> {enable|disable|list [<path> ...]|remove <path>| default-soft-limit <percent>} |
volume quota <VOLNAME> {limit-usage <path> <size> |soft-limit <path> <percent>} |
volume quota <VOLNAME> {alert-time|soft-timeout|hard-timeout} {<time>}

Volume op-versions calculations now take into account if an option,
a. enables/disables an xlator, or
b. is a boolean option.
This prevents op-versions from being updated when a feature is disabled.
Also, correctly close the dynamically loaded xlators in
xlator_volopt_dynload() and prevent leaks.

Integer volume options which specified only the min value as 0, would not be
validated during "volume set".
The range check for an option happened only if both min and max were not 0. In
the above case, even though a minium was specified, the range check did not
happen as both min and max were 0.
To allow forced validation in such cases, a new member, "validate", has been
added to volume_options_t. This member takes the values GF_OPT_VALIDATE_BOTH,
GF_OPT_VALIDATE_MIN and GF_OPT_VALIDATE_MAX (GF_OPT_VALIDATE_BOTH is the
default).

- Upon init/reconf, if an option is not in the opt dict,
and a default value is neither specified, null it out.
With this, the xlator config data that comes
out of init/reconf becomes deterministic in terms
of the xlator option declarations and the incoming
option value dictionary. (Needed for correct operation
of volume reset.)
- We can rely bravely on the guarantee given by init/reconf
as of which no NULL value is passed to the converter
functions. Drop the spurious null check of not_null(),
and rebaptize it to pass().

makes more important messages harder to find, so they're down to

This is the new version of the patch by Kaushik at review.gluster.com/699
The following new option types have been introduced:
* GF_OPTION_TYPE_INTERNET_ADDRESS_LIST
* GF_OPTION_TYPE_PRIORITY_LIST
* GF_OPTION_TYPE_SIZE_LIST
and option types of several options in translators have been updated to use the
new types.
valid_internet_address(), valid_ipv4_address() & valid_ipv6_address() functions
has been updated for * wildcard matching. Previously used standalone wildcard
address checking functions have been removed.
Changes have been done to stripe translator to correctly set, update and use
stripe-blocksize. Also minimum value for block-size has been set to 16KB.
