The number of supported file systems on a NAS server depends on the model.
By default, a server can support up to 128 filesystems at a time.
The maximum number of supported file systems for each model is:
Model | Maximum number of supported file systems |
4040 | 128 |
4060 / 4080 | 500 |
4100 / NAS module | 500 |
5200 / 5300 | 500 |
To increase the number of supported file systems from the default to the maximum, contact customer support.
For further information, see the CLI command filesystem-enable-max-count man page.
Per-span limits
By default, there is a limit of 32 filesystems per span. If you require a greater number of filesystems per span, it is possible to increase this number using the filesystem-create CLI command with the --exceed-safe-count option. This option must not be used when creating up to 32 filesystems. It must only be used when creating filesystems beyond the 32nd one.
Creating too many filesystems fills up the filesystem catalogue. The filesystem catalogue usage is dependent on the filesystem name lengths; the longer the name of the filesystem, the more space it consumes in the catalogue. Use the span-dump command to check the remaining space in the FS catalogue.
For example:
If the filesystem catalogue is full, this will cause the recycle bin to become unavailable. In this case, in order to delete a filesystem, it is necessary to use the filesystem-delete --no-undeletion-information option to bypass the recycle bin.
