During a software update, a system that has volumes near 128 TB of used physical space
alerts you to take certain measures to prevent them from becoming read only.
Compressed volumes near their size limits are monitored at specified thresholds to preserve data
integrity. If a volume can be shrunk to fit below the recommended new limit, you are advised to do
so. If volume capacity cannot be reduced to meet the recommended limit, you are advised to create a
non-compressed mirror of the data (if one does not exist) and delete the primary copy.
Note: Size limits for compressed volumes in data reduction
pools are not monitored.
Size limits
If
you are using compressed volumes in standard pools, these volumes
have the following size limits. If a new or existing compressed
volume in a standard pool approaches the maximum size, the system
issues an alert. Compressed volumes in data reduction pools do
not monitor size of the volumes.
- 96 TB
- Maximum virtual size of a new, individual
compressed volume. You cannot create a new compressed volume
that exceeds this size. In addition, you cannot increase the size
of an existing compressed volume beyond this value. If one or
more compressed volumes in a system exceed this limit, you
receive an alert. To reduce the risk of losing or corrupting
data, you must take action soon to remove data from the compressed
volume.
- 120 TB
- Maximum virtual size of an existing compressed
volume in a system. If any compressed volumes in the system
approach or exceed this value, the system issues an alert.
Important: Immediate action is required to remove all data from
the compressed volume and prevent the loss of data.
- 128 TB
- Maximum physical size of a compressed
volume.
