Re: How to enable shared_storage?

[Alexandr Porunov <alexandr.porunov@xxxxxxxxx>]

I have disabled shared_storage then removed that folder (/var/run/gluster/shared_storage). Then I have enabled shared_storage again.

Here is the execution of the commands after that:

# gluster volume info

Volume Name: gv0

Type: Replicate

Volume ID: ddff3200-ff93-429f-990f-648b6d9ec237

Status: Started

Snapshot Count: 0

Number of Bricks: 1 x 3 = 3

Transport-type: tcp

Bricks:

Brick1: 192.168.0.124:/data/brick1/gv0

Brick2: 192.168.0.125:/data/brick1/gv0

Brick3: 192.168.0.126:/data/brick1/gv0

Options Reconfigured:

nfs.disable: on

performance.readdir-ahead: on

transport.address-family: inet

cluster.enable-shared-storage: enable

# gluster peer status

# ls /var/run/gluster/

If I manually create a folder /var/run/gluster/shared_storage to all nodes it still doesn't work. What I am doing wrong?

I have created that dir:

# mkdir -p /var/run/gluster/shared_storage

and then:

# mount -t glusterfs 127.0.0.1:gluster_shared_storage /var/run/gluster/shared_storage

Mount failed. Please check the log file for more details.

Where to find a proper file to read logs? Because "/var/log/glusterfs/" has a lot of log files.

Sincerely,

Alexandr

Hello,

I try to enable shared storage for Geo-Replication but I am not sure that I do it properly.

Here is what I do:
# gluster volume set all cluster.enable-shared-storage enable
volume set: success

# mount -t glusterfs 127.0.0.1:gluster_shared_storage /var/run/gluster/shared_storage
ERROR: Mount point does not exist
Please specify a mount point
Usage:
man 8 /sbin/mount.glusterfs

This error means /var/run/gluster/shared_storage directory does NOT exists.

But, running the  command (gluster volume set all cluster.enable-shared-storage enable)
should carry out the mounting automatically. (so, there is no need to manually mount).

Check after running "gluster volume set all cluster.enable-shared-storage enable"
    1. gluster volume info
     2. glusterfs process started with volfile-id as gluster_shared_storage.

Thanks,
Saravana
