Failure in Mounting a Parallel File System

This section described some typical reasons a parallel file system may not mount and what actions you can take to resolve the issue.

Symptom 1: "The specified bucket does not exist" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

The parallel file system to be mounted does not exist.

Solution

Create a parallel file system and mount it again. For details about how to create a parallel file system, see Creating a Parallel File System.

Symptom 2: "file system not support this request: this bucket not support filesystem" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

The mounted bucket is not a parallel file system.

Solution

Create a parallel file system and mount it again. For details about how to create a parallel file system, see Creating a Parallel File System.

Symptom 3: "The request signature we calculated does not match the signature you provided. Check your key and signing method." or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

Authentication failed. The access keys (AK and SK) are incorrect.

Solution

Check whether the AK and SK information in the key file is correctly configured. For details about the check method, see 3 in the section "Initializing obsfs."

Symptom 4: "specified passwd_file is not readable" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

The key file path configured in the passwd_file file is incorrect.

Solution

Check whether the key file path configured in the passwd_file file is correct. For details about the check method, see 3 in the section "Initializing obsfs."

Symptom 5: "Access Denied" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

Authentication failed. The IAM user does not have OBS operation permissions.

Solution

Authorize the user with required OBS operation permissions. For details, see Resource Preparation.

Symptom 6: "unable to access MOUNTPOINT /obsfs: Transport endpoint is not connected" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

The mount point is occupied by another obsfs mount process.

Solution

Run the df command to query the partitions and points that have been mounted to. Then select an unoccupied mount point and mount the bucket again.

Symptom 7: "unknown option" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

One or more parameters in the mount command are incorrectly set and therefore failed to be identified by obsfs.

Solution

Check the mount parameters by referring to Table 1 in the section "Mounting the Parallel File System".

Symptom 8: "unable to access MOUNTPOINT /mnt/obsfs: No such file or directory" or Similar Errors Occur When Mounting a Parallel File System

Fault Locating

The mount directory does not exist.

Solution

Use the mkdir command to create a directory or mount the bucket to an existing directory.
