NFS mkdir cannot create directory read only file system

Have trouble with the “NFS mkdir cannot create directory read-only file system” error?

According to our experts, this error often occurs when we try to create a directory on an NFS that is mounted as read-only. NFS is a protocol that allows remote file systems to be mounted over a network.

When mounting an NFS share, it can be mounted in one of two modes:

• Read-write (RW):
  This mode allows both reading from and writing to the file system.
• Read-only (RO):
  This mode only permits reading from the file system. If we try to write to it will result in an error.

How to Resolve the Error

• If you have the necessary permissions and access to the NFS server, we can remount the NFS share with read-write permissions. Also, update the mount options in the /etc/fstab file or use the mount command.
• Then, make sure the NFS server is configured to allow write access to the directory you’re trying to create.
• Verify the NFS client’s configuration to make sure it is not mounting the NFS share as read-only.
• Furthermore, check if you have permission to create directories on the NFS share. Even if the share is mounted as read-write, we may run into if the user does not have the needed permissions.
• Also, make sure the NFS server is functioning correctly.

With the above troubleshooting tips, we can resolve the NFS mkdir read-only file system error with ease.
