MOGADM(1) User Contributed Perl Documentation MOGADM(1)NAMEmogadm - MogileFS admin tool
SYNOPSIS
$ mogadm [config options] <argument(s)> [argument options]
$ mogadm
....
(prints contextual help, if missing command/arguments)
...
OPTIONS
--lib=/path/to/lib
Set this option to a path to include this directory in the
module search path.
--trackers=10.0.0.117:7001,10.0.0.118:7001,...
Use these MogileFS trackers for status information.
ARGUMENTS
check Check to ensure that all of the MogileFS system components are
functioning and that we can contact everybody. The quickest
way of ensuring that the entire MogileFS system is functional
from the current machine's point of view.
host add <host> [host options]
host modify <host> [host options]
host mark <host> <status>
host delete <host>
host list
Functions for manipulating hosts. For add and modify, host
options is in the format of normal command line options and can
include anything in the "HOST OPTIONS" section.
device add <host> <device id>
device mark <host> <device id> <status>
device modify <host> <device> [device options]
device delete <host> <device>
device list
device next
Functions for manipulating devices. For add and modify, device
options are in the format of normal command line options and
can include anything in the "DEVICE OPTIONS" section.
domain add <domain>
domain delete <domain>
domain list
Simple commands for managing MogileFS domains. Note that you
cannot delete a domain unless it has no classes and is devoid
of files.
class add <domain> <class> [class options]
class modify <domain> <class> [class options]
class delete <domain> <class>
class list
Commands for working with classes. Please see the "CLASS
OPTIONS" section for the options to use with add/modify. Also,
delete requires that the class have no files in it before it
will allow the deletion.
slave ...
Add/remove slaves replicating from MogileFS master database.
TODO: detail this
Run mogadm slave by itself for contextual help.
fsck printlog
fsck taillog
fsck clearlog
Display or clear the log of fsck events.
fsck reset [fsck options]
Reset fsck position back to the beginning. Please see the
"FSCK OPTIONS" section for options to use with fsck.
fsck start
Start (or resume) background fsck from the last checked fid. If
you want to check every fid, you must call fsck reset before
calling start.
fsck status
Show the status of the presently active (or last if none
active) fsck. This includes what FIDs are being checked, time
statistics, check type as well as a summary of problems
encountered so far.
fsck stop
Stop (pause) background fsck
settings list
Display all present MogileFS settings.
settings set <key> <value>
Set the server setting for 'key' to 'value'.
The current settings are <enable_rebalance> (set to 1 to start
rebalance mode to move files to under-used devices) and
<memcache_servers> (enable memcached caching in the tracker).
HOST OPTIONS
--ip=<ip of host>
--port=<port of mogstored on host>
Contact information for the host. This is the minimum set of
information needed to setup a host.
--getport=<alternate retrieval part on host>
If provided, causes the tracker to use this port for retrieving
files. Uploads are still processed at the standard port.
--altip=<alternate IP>
--altmask=<mask to activate alternate IP>
If a client request comes in from an IP that matches the
alternate mask, then the host IP is treated as the alternate IP
instead of the standard IP. This can be used, for example, if
you have two networks and you need to return one IP to reach
the node on one network, but a second IP to reach it on the
alternate network.
--status=<host status>
Valid host statuses are one of: alive, down, dead.
DEVICE OPTIONS
--status=<device status>
Valid device statuses are one of: alive, dead, down, drain,
readonly.
--weight=<device weight<gt>
The weight used in calculation of preferred paths. It must be a
positive integer.
CLASS OPTIONS
--mindevcount=<value>
Number of devices the files in this class should be replicated
across. Can be set to anything >= 1.
--replpolicy=<value>
Stringified replication policy. ie "MultipleHosts(3)" is
equivalent to a --mindevcount=3. See documentation or plugins
on alternative policies.
--hashtype=<value>
Name of the hash algorithm used for checksumming. "MD5" or
"NONE" for no checksumming.
FSCK OPTIONS--policy-only
Check replication policy (assumed locations) only; don't stat
storage nodes for actual file presence.
EXAMPLES
Host manipulation:
$ mogadm host list
$ mogadm host add foo.local
$ mogadm host add foo.local --status=down --ip=10.0.0.34 --port=7900
$ mogadm host mark foo.local down
$ mogadm host modify foo.local --port=7500
$ mogadm host delete foo.local
Device manipulation:
$ mogadm device list
$ mogadm device summary
$ mogadm device summary --status=dead,down
$ mogadm device next
$ mogadm device add foo.local 16
$ mogadm device add foo.local 17 --status=alive
$ mogadm device mark foo.local 17 down
$ mogadm device modify foo.local 17 --status=alive --weight=10
$ mogadm device delete foo.local 17
Domain manipulation:
$ mogadm domain list
$ mogadm domain add first.domain
$ mogadm domain delete first.domain
Class manipulation
$ mogadm class list
$ mogadm class add first.domain my.class
$ mogadm class add first.domain my.class --mindevcount=3
$ mogadm class add first.domain my.class --replpolicy="MultipleHosts(3)"
$ mogadm class modify first.domain my.class --mindevcount=2
$ mogadm class modify first.domain my.class --replpolicy="MultipleHosts(3)"
$ mogadm class delete first.domain my.class
Check the status of your entire MogileFS system:
$ mogadm check
Check every file in the entire MogileFS system:
$ mogadm fsck reset
$ mogadm fsck start
$ mogadm fsck status
$ mogadm fsck printlog
See all the things mogadm can do:
$ mogadm
Get help on a sub-command:
$ mogadm device
CONFIGURATION
It is recommended that you create a configuration file such as
"/etc/mogilefs/mogilefs.conf" (or at "~/.mogilefs.conf") to be used for
configuration information. Basically all you need is something like:
trackers = 10.0.0.23:7001, 10.0.0.15:7001
# if MogileFS::Admin files aren't installed in standard places:
lib = /home/mogilefs/cgi-bin
Note that these can also be specified on the command line, as per
above.
