Mounting from an Amazon Elastic Compute Cloud instance
You can mount your file system from an Amazon EC2 instance.
To mount your file system from Amazon EC2
-
Connect to your Amazon EC2 instance.
-
Make a directory on your FSx for Lustre file system for the mount point with the following command.
$ sudo mkdir -p /fsx
-
Mount the Amazon FSx for Lustre file system to the directory that you created. Use the following command and replace the following items:
Replace
with the actual file system's DNS name.file_system_dns_name
Replace
with the file system's mount name. This mount name is returned in themountname
CreateFileSystem
API operation response. It's also returned in the response of the describe-file-systems Amazon CLI command, and the DescribeFileSystems API operation.
sudo mount -t lustre -o relatime,flock
file_system_dns_name
@tcp:/mountname
/fsxThis command mounts your file system with two options,
-o relatime
andflock
:-
relatime
– While theatime
option maintainsatime
(inode access times) data for each time a file is accessed, therelatime
option also maintainsatime
data, but not for each time that a file is accessed. With therelatime
option enabled,atime
data is written to disk only if the file has been modified since theatime
data was last updated (mtime
), or if the file was last accessed more than a certain amount of time ago (6 hours by default). Using either therelatime
oratime
option will optimize the file release processes.Note
If your workload requires precise access time accuracy, you can mount with the
atime
mount option. However, doing so can impact workload performance by increasing the network traffic required to maintain precise access time values.If your workload does not require metadata access time, using the
noatime
mount option to disable updates to access time can provide a performance gain. Be aware thatatime
focused processes like file release or releasing data validity will be inaccurate in their release. -
flock
– Enables file locking for your file system. If you don't want file locking enabled, use themount
command withoutflock
.
-
Verify that the mount command was successful by listing the contents of the directory to which you mounted the file system, /mnt/fsx by using the following command.
$
ls /fsx
import-path lustre $You can also use the
df
command, following.$
