R -
This indicates the volume in the Name column is mounted on
another client workstation with Read-Only access.
- (dash) -
This indicates the volume in the Name column has not been
mounted by any workstation or the TerraBlock Server on the network.
State –
The state of a volume is related to the physical drives that comprise the
volume. The possible states are “OK”; “DEGRADED”; “DAMAGED”; “RECOVERING”.
OK -
The physical drives installed in the TerraBlock Server that
comprise the volume are all present and working. This state will exist
under normal operation, or after a drive recovery is complete.
DEGRADED
-
A physical drive in the group that comprises the volume
has failed or incurred an error, and data has been written to the volume
since the drive failure occurred. If the volume is protected, the state will
return to ‘OK’ once the volume recovery is complete.
DAMAGED
–
Multiple physical drive failures have occurred affecting
individual volumes (this will occur on a volume by volume basis). This
state can also occur if a volume is using the DynaRAID setting
‘Unprotected’ (no raid) and an individual physical drive is replaced. This
condition is very rare, and drives may be re-activated and data salvaged,
only in cases where a drive replacement has not occurred. Contact Facilis
Customer Support
if a volume shows ‘Damaged.’
RECOVERING
-
A physical drive in the group had failed and was
reactivated or replaced. A protected volume will show ‘Recovering’ while
the recovery process is active and the drive set is being repaired. Use the
SMDriveMonitor application (yellow icon), located on the TerraBlock
Server, for real-time updates on the recovery process.
Size –
The size of the volume given at the time of creation by the administrator.
When using Auto-format, the volume size will match the partition size in the client
OS. If formatting volumes manually, the volume must be formatted the same size
set in the TerraBlock Manager, and not partitioned into smaller sections at the client
station. The size of a volume can be increased after creation.
Group –
The group column is related to the group of physical drives used to create
the volume on the server. The graphic below lists some common drive group number
examples:
1 (group 1 only)
2 (group 2 only)
1,2 (group 1 and 2 (tandem))
The numbers apply to either each group of 12 drives in a 24D unit (24 drives total),
or one group of 12 drives in a 24EX (12 drives total) or 8 drives on the 8XS (8 drives
total).
