I have installed emacs with yum and now I'm trying to create a .emacs file and put some commands in it, but I can't type anything in the emacs buffer. It says the buffer is read-only. I exited emacs and did touch .emacs and I get a message that it can't do that on a read-only file system. I googled around to see why this might be, but I can't see any links on this. Any tips why this might be doing this? I've heard that centos is strict on changes, but I don't know the extent it restricts changes. I followed a page where I did echo 0 >/selinux/enforce . But this is only good until reboot. But shouldn't I be now able to make changes in ~*
Thanks,

usually a disk failure when that happens out of the blue. try writing to /dev/shm/ if you have to save a file. (That's a virtual fs in memory, so be advised it will disappear on reboot.) check dmesg for errors.

That was it. This is an old mac pro that I put centos on yesterday. It had 4 disks in it and this is the 3rd that has died. A faculty member had it for 5-6 years and it was on 24/7. It's been in the junk pile for several months. I guess long enough for the disks to go south from sitting on so long then going off for a period... maybe.... Anyone heard of this?
Thanks,
Wes

It is hard to predict hard disk failure. I have had "sealed" Seagate enterprise grade disks DoA.
Install smartd (smartctl) and watch the logs for impending failures and take corrective actions when you start noticing failures in the smart report; even this is not full proof. RAID gives some comfort level but do keep backup of important data in multiple places.

Your home directory must belong to you and have write permission as shown by the "w" in the drwx at the beginning of the line above.
You can open up your permissions if you feel so inclined but I wouldn't suggest it.

As you found, SELinux was not at fault,
echo 0 > /selinux/enforce
Is immediate, it will put the machine into permissive mode. setenforce 0, is a better command to do this.
On reboot SELinux would be back to the original state. If you want to alter the default state of SELinux, you do this through /etc/selinux/config.
