Using Multipath Storage
Last updated
Last updated
To enable multipath storage (iSCSI, Fibre Channel) and configure multipathd daemon in Catalogic vStor:
Attention! Configuring and enabling multipathd
on the Catalogic vStor server is critical. Without it, a single disk might appear with multiple labels (like /dev/sda
and /dev/sdb
), leading to pool management and reporting issues.
Log In: Access the vStor server shell using the admin account, typically via an SSH client.
Create Configuration: Execute sudo mpathconf --enable
to generate a multipath configuration file at /etc/multipath.conf
.
Start Multipath Daemon: Run sudo systemctl enable --now multipathd
to start and enable the daemon.
Verify Daemon Status: Ensure that the multipathd service is active and running by executing systemctl status multipathd
.
Mapping Devices: Starting the multipathd daemon also generates new device paths in /dev/mapper
, identified as mpath<x>
. To view the mapping layout, use sudo multipath -ll
.
Usage in Volume and File System Management: When creating volumes, partitions, or mounting file systems, refer to these mpath<x>
names within /dev/mapper
for accurate device identification and management.
