[Gluster-users] gluster-volgen - syntax for mirroring/distributing across 6 nodes

[Lakshmipathi]

Hi Phil,
1)Yes,your glusterfs-volgen command should  provide the required volume files for your setup ,but you can also use this,

glusterfs-volgen --name repstore1 --raid 1 clustr-01:/mnt/data01 clustr-02:/mnt/data01 clustr-03:/mnt/data01 clustr-04:/mnt/data01 
clustr-05:/mnt/data01 clustr-06:/mnt/data01 -c ~/files/ 

will create volume files under your home , make sure you have ~/files directory already exists.


2)No currently glusterfs-volgen won't support shorthand methods for export directories  - they need to be exact strings.

For more details on volgen - please check

Cheers,

Subject: [Gluster-users] gluster-volgen - syntax for mirroring/distributing	across 6 nodes

NOTE: posted this to gluster-devel when I meant to post it to gluster-users

01 | 02 mirrored --|
03 | 04 mirrored --| distributed
05 | 06 mirrored --|

1) Would this command work for that?
glusterfs-volgen --name repstore1 --raid 1 clustr-01:/mnt/data01
clustr-02:/mnt/data01 --raid 1 clustr-03:/mnt/data01
clustr-04:/mnt/data01 --raid 1 clustr-05:/mnt/data01
clustr-06:/mnt/data01

So the 'repstore1' is the distributed part, and within that are 3 sets
of mirrored nodes.

2) Then, since we're running 24 drives in JBOD mode, so we've got
mounts from /mnt/data01 - /mnt/data24.  Is there a way to write this
in shorthand, because the last time I generated a config across 3 of
these hosts, the command looked like this:

glusterfs-volgen --name store123 clustr-01:/mnt/data01
clustr-02:/mnt/data01 clustr-03:/mnt/data01 clustr-01:/mnt/data02
clustr-02:/mnt/data02 clustr-03:/mnt/data02 clustr-01:/mnt/data03
clustr-02:/mnt/data03 clustr-03:/mnt/data03 clustr-01:/mnt/data04
clustr-02:/mnt/data04 clustr-03:/mnt/data04 clustr-01:/mnt/data05
clustr-02:/mnt/data05 clustr-03:/mnt/data05 clustr-01:/mnt/data06
clustr-02:/mnt/data06 clustr-03:/mnt/data06 clustr-01:/mnt/data07
clustr-02:/mnt/data07 clustr-03:/mnt/data07 clustr-01:/mnt/data08
clustr-02:/mnt/data08 clustr-03:/mnt/data08 clustr-01:/mnt/data09
clustr-02:/mnt/data09 clustr-03:/mnt/data09 clustr-01:/mnt/data10
clustr-02:/mnt/data10 clustr-03:/mnt/data10 clustr-01:/mnt/data11
clustr-02:/mnt/data11 clustr-03:/mnt/data11 clustr-01:/mnt/data12
clustr-02:/mnt/data12 clustr-03:/mnt/data12 clustr-01:/mnt/data13
clustr-02:/mnt/data13 clustr-03:/mnt/data13 clustr-01:/mnt/data14
clustr-02:/mnt/data14 clustr-03:/mnt/data14 clustr-01:/mnt/data15
clustr-02:/mnt/data15 clustr-03:/mnt/data15 clustr-01:/mnt/data16
clustr-02:/mnt/data16 clustr-03:/mnt/data16 clustr-01:/mnt/data17
clustr-02:/mnt/data17 clustr-03:/mnt/data17 clustr-01:/mnt/data18
clustr-02:/mnt/data18 clustr-03:/mnt/data18 clustr-01:/mnt/data19
clustr-02:/mnt/data19 clustr-03:/mnt/data19 clustr-01:/mnt/data20
clustr-02:/mnt/data20 clustr-03:/mnt/data20 clustr-01:/mnt/data21
clustr-02:/mnt/data21 clustr-03:/mnt/data21 clustr-01:/mnt/data22
clustr-02:/mnt/data22 clustr-03:/mnt/data22 clustr-01:/mnt/data23
clustr-02:/mnt/data23 clustr-03:/mnt/data23 clustr-01:/mnt/data24
clustr-02:/mnt/data24 clustr-03:/mnt/data24

Thanks
