GlusterFSに取り組んでみて

I like ...

!  Module architecture
 Clean, beautiful and pluggable
!  Elastic Hashing Algorithm
 The best way at present
!  Performance translators
 Ingenious attempt as an userspace filesystem
!  The community!
 Many tough developers and cool hackers!


But we also need ...

!  Thin-provisioning feature
 For capital spending cuts
!  Cleaning 0 byte sparse files
 For inode shortage avoidance
!  Controlling silent data corruption
 For long term service providing
!  REST API for operation and monitoring
 Can oVirt do it?
! libglusterfsclient again!
 Be lost to the history (available until 3.0.x)


Some kind of!
ULTIMATE GlusterFS!
which I devise

ぼくのかんがえたさいきょうのGlusterFS

Some kind of ULTIMATE GlusterFS which I devise

GlusterFS’ front-end is enough cool. But rather back-end
can be expanded. Simply mix cloud and on premise
storages to provide services in a good balance.

cluster/dht
Distributing data
Between local file
system and Amazon S3
cluster/afr cluster/afr

storage/posix storage/posix storage/s3 storage/s3
cluster/afr

One of paired
replicas is saved in
storage/posix storage/s3 S3


Some kind of ULTIMATE GlusterFS which I devise

File storage and object storage are both achieved.
To become truly unified storage,
block storage interface should be implemented.

FUSE NFS swift iSCSI target

cluster/dht


Focus!
on the!
Community

コミュニティについて

Focus on the community

!  High interests in Japan, not only English-
speaking countries
 About 30 cutting-edge engineers had a discussion
in GlusterFS round-table talk.
 Engaging in a heated Qs and As in front of 100
people in Cloud Storage Conference.
 Regardless of professions or places of employment,
about 6 of 45 already had experiences with
GlusterFS in InfiniBand DAY 05.
 A few companies ask us consult as to GlusterFS.
!  But Japanese are ...
 Not good at English (especially speaking and listening)
 Shy
 GMT+9 (a long time distance on the earth far, far away ....)
Japanese localized community is important.
Let’s get it started! 19
