While I was experimenting with the quotas I changed the following line in the /etc/fstab :
LABEL=/ / ext3 defaults 1 1 (BEFORE)
LABEL=/ / ext3 defaults,userquotas 1 1 (AFTER)
Now, I cannot write anything to the /, nor I cannot change any of the files including /etc/fstab
I am using RedHat 7.3. When I look at the file permissions I see that I have read and write permissions. I cannot change the file permissions either.
Any help is greatly appreciated.
