Limitations of Flexible Storage Sharing

Following are the limitations for using FSS:

  • You cannot grow or shrink the file system unless all of the nodes in the cluster are online. Similarly, you cannot create a new file system, destroy a file system, or create a volume-level snapshot unless all of the nodes in the cluster are online.

  • File systems with local disks support only full-sized rollbacks, not space-optimized rollbacks.

Table: Commands not supported for FSS

Commands not supported for FSS

Description

Storage> fs addcolumn

Storage> fs addmirror

You cannot change the layout for file systems that have DAS disks by adding columns or mirrors.

Storage> fs rmcolumn

Storage> fs rmmirror

You cannot change the layout for file systems that have DAS disks by removing columns or mirrors.

Storage> fs setfastresync

Storage> fs unsetfastresync

FastResync is always enabled for file systems that have DAS disks.

Storage> rollback create space-optimized

File systems with DAS disks support only full-sized rollbacks.
