CentOS 6 GUI login loop.

I think turning the NAS back on will have fixed the disk space issue cause I haven’t done but a couple images since I got it going. Here is the df output.

@ManofValor Your root partition is 100% full. That’s the problem.

@Wayne-Workman
So I can’t login cause it’s full? -
@Wayne-Workman
I don’t understand, I haven’t put anything on there to fill it up? -
@ManofValor because your /home is at the same place at your / and when you try to login, some files maybe touched and this prevent you to enter.

How did it fill up when I didn’t do anything? -
@ManofValor Seeing as /images (or whatever your relevant storage point is) is expected to be on the NAS, I’d recommend cleaning out the current storage location as it’s located on your main disk. You could just do something like:
Unmount the current NAS if it is already mounted with:
umount /imagesThen check the /images directory and remove any files in there. This is entirely up to you at this point, I’m giving you how to fix, make sure you don’t delete all your current NAS images.
rm -rf /images/*Then try to mount the nas.

@Tom-Elliott Very good thinking, Tom. If the NAS was off, mounting failed, and any images you captured would have gone straight onto the root partition. ESPECIALLY since I remember ManOfValor running the installer so many times before having the NAS correctly configured, the needed .mntcheck files and dev folder would absolutely be present, so any upload would go until space ran out.
@ManofValor Try Tom’s advice - but you must be careful, you MUST successfully unmount the /images directory for the NAS, and you SHOULD confirm and reconfirm that it unmounted correctly. Being new to linux, after this command I’d even suggest you turn the NAS off after unmounting. Then run the delete commands that Tom posted. Then run
df -hto check free space. If the root partition is substantially free’d up, then hook everything back up, turn it on, give the server a reboot, and see if things work.Tom’s commands would also ensure that uploading will never work without the NAS being properly mounted - unless of course you run the installer without the NAS being mounted, as the installer would re-create those needed files/folders for image capture on the root partition.
Let us know how it goes.

Also, the problem was found, but it’s not solved yet, so I marked the thread unsolved. I don’t want others to not bother reading & helping because they think it’s solved.

@Wayne-Workman
Good morning,
Everything on the NAS is just tests, so if I don’t care what’s deleted then I don’t need to unmount, right? -
@ManofValor You would still need to unmount, because the space is used by your main system. Simply removing all the data in the mounted partition will only free up space on the mount point.

@Tom-Elliott
Ok, this thread is solved. After I deleted everything I was able to login. Thanks again guys.
