mogile database:
|
|
|
|
* add UUID to device table
|
|
|
|
mogilefsd:
|
|
|
|
* when storing files, also store 00003443.meta with info about file
|
|
- this is so we can restore the database if it totally crashes
|
|
- can also store checksumming info in the .meta file?
|
|
* other jobs (replicator & delete, etc) can connect to frontend and do spud-like variable setting
|
|
* fix request pipelining problem (make it an option, though?)
|
|
* host dead cache:
|
|
- when any jobs notices a mogstored state change, send to parent
|
|
- parent rebroadcasts to kids, so they share info
|
|
* UDP between peers for jobs to cross-communicate
|
|
- in conf file, "peers: 10.x.y.z:6001, 10.a.b.c:6001"
|
|
* running fs verifier that makes sure UUIDs from mogstored matches database
|
|
- if a host fails verification, mark it as down
|
|
- configurable "verify time" (default 300 seconds)
|
|
- over 300 seconds, verify another device every N seconds (300/X = N, X = number of devices)
|
|
* rebalancer job (future)
|
|
- moves files around to devices with less files
|
|
* free space weighting
|
|
- every N seconds, using usage file, update database free space columns
|
|
- jobs update their in memory space cache every 60 seconds or so
|
|
- new files go to devices depending on free space (weighted algorithm)
|
|
- new job to update mb_* columns
|
|
- new column, mb_asof for date last updated
|
|
- email alerts when mb_asof is old
|
|
* checksum files (future)
|
|
* FUSE interface (future)
|
|
* require InnoDB backend
|
|
|
|
mogstored:
|
|
|
|
* support configuration files
|
|
* allow OPTIONS request
|
|
- include "Date: <gmt date>" header
|
|
* run usage file creator in different thread
|
|
* smartd dump just like usage file
|
|
* fsinfo dump
|
|
- include UUID of fs
|
|
- run in new thread (with usage?)
|
|
- mount -P to get fs types
|
|
|
|
mogadm:
|
|
|
|
* example commands:
|
|
- check
|
|
- <host> add disk <disk>
|
|
- <host> down disk <disk>
|
|
- <host> kill disk <disk>
|
|
- <host> down
|
|
- <host> up

moginit
|
|
|
|
* create new mogilefs database
|
|
* perform database upgrades
