mkdir: cannot create directory: Read-only file system (Tried sudo and chmod)


Greetings!

Whenever I tried to create directory it give me this error,"mkdir: cannot create directory: Read-only file system".

Some folders are shared between two servers so I created folder from one and want to use the other server for computation but it is unable to store any of the files or to write any file on the computational server.

I have tried sudo command as
sudo mkdir try

and chmod command as
sudo chmod -R 775 try

but no use. I have found the threads related to it but none of it helped me.

Looking forward for your support in this regard.

Thanks in advance!

As the error message says, you try to write on a file system that is mounted as read-only (for whatever reason). This simply won't work.
Please post the output of
Code:
mount
and the exact location where you try to create the directory.

Thanks for such a quick reply!

The output of mount is

proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/mapper/VolGroup_ID_11645-LogVol2 on /tmp type ext3 (rw)
/dev/mapper/VolGroup_ID_11645-LogVol4 on /usr type ext3 (rw)
/dev/sdb3 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
/dev/mapper/VolGroup_ID_11645-LogVolHome on /home type ext3 (rw)

linux1:/imgdata on /imgdata type nfs (rw,bg,addr=10.248.0.163)

The exact location is /extdata1/soft/Cufflinks on the server linux2 (computational server)

Hope it helps!

It is probably a problem on the server computer, not the one you are typing the command from.

Check the permissions on the server.

Thank you so much for the reply!

I am checking the server permission on the servers and will provide you feedback afterwards
