Synchronizing RAID
All 26000/28000 appliances support two storage devices (excluding 28600HS).
In appliances that use two storage devices, RAID1 mirroring across both storage devices is used. This lets
the appliance continue to work if there is a storage device failure.
The mirror rebuild is automatic. Both storage devices must be the same type.
First Boot Up
At first boot up, wait for up to six hours to let the storage devices fully synchronize. If you reboot the
appliance before the storage devices are synchronized, the synchronization starts again from scratch at
the next boot.
To monitor the RAID status of the storage devices from the CLI:
1.
Connect to the command line on the appliance.
2.
Log in to
Gaia Clish
or the
Expert mode
.
3.
Run this command to monitor the RAID status of the storage devices:
raid_diagnostic
This command shows data about the RAID and storage devices, with the percent of synchronization
done.
DiskID 0
is the left storage device.
DiskID 1
is the right storage device.
After the first boot and after you replace a second storage device, the RAID state (in the VolumeID
line) shows
DEGRADED
(this indicates that the drives are not synchronized). The DiskID:0 state
shows
ONLINE
and the DiskID:1 state shows
INITIALIZING
.
After the RAID is synchronized, the RAID state (in the VolumeID line) shows
OPTIMAL
(this
indicates that the drives are synchronized). The DiskID:0 and DiskID:1 states show
ONLINE
.
For example:
MyAppliance> raid_diagnostic
This example shows that the storage devices are fully synchronized (disk sizes and vendor may
vary).
To monitor the RAID status of the storage devices from the
Gaia Portal
:
1.
Log in to the
Gaia Portal
.
2.
From the left tree, click
Maintenance
>
RAID Monitoring
