Updating a volume configuration

Open the Amazon FSx console at https://console.amazonaws.cn/fsx/.

Navigate to File systems and choose the FSx for OpenZFS file system that you want to update a volume for.

Choose the Volumes tab.

Choose the volume that you want to update.

For Actions, choose Update volume.

The Update volume dialog box displays with the volume's current settings.

For Storage capacity quota - optional, you can set a quota that will be the maximum storage size for the volume. This quota cannot be larger than the parent volume quota. To set no quota and allow this volume to consume any available capacity in your file system, set this property to -1.

For Storage capacity reservation - optional, you can enter the reservation for the volume. This reserves dedicated space on the file system storage pool, meaning the space available to all other volumes is reduced by the amount specified. It cannot be set to a value that's greater than the parent volume quota or the remaining reservation space on the file system storage. To set no reservation and allow this volume to consume any available capacity in your file system, set this property to 0 or -1.

For Data compression type, choose the type of compression to use for your volume—either Zstandard, LZ4, or No compression. Zstandard compression provides more data compression and higher read throughput than LZ4 compression. LZ4 compression provides less compression and higher write throughput performance than Zstandard compression. Changing this property affects only newly-written data. For more information about the storage and performance benefits of volume data compression options, see Data compression.

For NFS exports, you can modify or remove the existing client configurations that define which clients can access the volume and what permissions they have.

You can provide additional client configurations for the volume:

1. In the Client addresses field, specify which clients can access the volume. Enter an asterisk (*) for any client, a specific IP address, or a CIDR range of IP addresses.

2. In the NFS options field, enter a comma-delimited set of exports options. For example, enter rw to allow read and write permissions to the volume.

3. Choose Add client configuration.

4. Repeat the procedure to add another client configuration.

For more information, see NFS exports.

For Record size, choose whether to use the default suggested record size of 128 KiB, or to set a User-configured suggested record size for the volume. Generally, workloads that write in fixed small or large record sizes may benefit from setting a custom record size, like database workloads (small record size) or media streaming workloads (large record size). We recommend the default setting for the majority of use cases. For more information about the record size setting, see Volume properties.

For User and group quotas, you can change or set a storage quota for a user or group:

1. For Quota type, choose USER or GROUP.

2. For User or group ID, enter a number that is the ID of the user or group.

3. For Usage quota, enter a number that is the storage quota in GiB of the user or group.

4. To create additional user or group quotas, choose Add quota and repeat the procedure to change or add a quota for another user or group.

For Record size, enter the desired maximum size of a logical block in a ZFS dataset. Valid values are 4, 8, 16, 32, 64, 128, 256, 512, or 1024 KiB. The default is 128 KiB. Most file systems will use the default value. Database workflows can benefit from a smaller record size, while streaming workflows can benefit from a larger record size. For more information about Record size and file system performance, see ZFS record size.
