Errno:95 unable to create link on mounted server disc

Install, Configure and Update
1

I am trying to process data files from a synology server, which is mounted on ubuntu as /mnt/cryoEM. While cryosparc is able to see the data, it is unable to produce a link. The permissions are all there as 777 for any file and/or directory, but still returns the error. Is there a workaround this, or are there specific permissions we need to set on Cryosparc to get this running?

@cdeivanayagam Please can you post the output of the command

grep '/mnt/cryoEM' /proc/mounts
3

Unfortunately, it does not give me any outputs when I process this command.

What about the commands

grep -i '/mnt/cryoEM' /proc/mounts
df -h

Here’s the output: there was a mistake on the CryoEM, where C being capital. Now it shows this.

A google search suggested that symbolic link support may be possible on cifs.

No idea on my side on how to execute this possibility. Do you have any?

added ‘mfsymlinks’ to the mount command and it is now working. Thank you for pointing me in the right direction.
