FAQ
Are there any restrictions on the use of file storage?
The file storage has certain restrictions on file system capacity, maximum file length, protocol version, etc. Please refer to the Product Restrictions section for detailed information.
What access protocols does file storage support?
UPFS only supports the POSIX protocol during the public beta period, and the NFSv3 protocol is under development.
Does file storage allow cross-region access?
UPFS does not support cross-region access.
Does file storage allow cross-project group access?
UPFS does not support cross-project group access during the public beta period.
Is there a limit on the number of host clients that can access a single file system?
Client hosts access through the mount point corresponding to the file system, and there is no limit to the number of cloud hosts in the same project that the file system can be mounted to.
Are there any special operations required before deleting a file system?
Yes, before deleting a file system, please first ensure that the data in the file system will no longer be used. Currently, during the public beta period, file storage does not provide data recovery functionality, so please be cautious with deletion operations. Before deleting the file system, ensure that all hosts using the file system have unmounted it; otherwise, residual instances of the deleted file system on the host will affect the host’s operation.
How to check the current running client version?
Check the binary file of the currently running upfs client process:
ls -l /proc/pidof upfs_client/exe CopyErrorSuccess
If there are multiple UPFS mounts, filter the processes by the file system name with the upfs-* prefix.
How to upgrade the client version?
Please refer to the Client Installation chapter to download and install the latest version. If there are existing mounts, you need to unmount the file system first and then remount it.
Please confirm that the version information output after successful mounting is consistent with the latest version.
