Failure in Mounting a Parallel File System
This topic describes the possible causes of and solutions to common failures in mounting parallel file systems.
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 has been 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.
