I can't make my file system, Ubuntu says it is "read-only"?

Need some help choosing hardware? Having trouble getting some hardware working? Just want to talk about hardware?

I can't make my file system, Ubuntu says it is "read-only"?

Postby GoingCrazy » April 23rd, 2014, 2:10 pm

Hi I'm pretty new at this, but love the how-to guide you've put together. Thanks so much.

I'm running Precise Pangolin on a 500GB drive (using only 50GB for the OS) and attempting to set-up the "userData" LVM to utilize the rest of the drive. I can create the new LVM just fine, but when I go to create the file system, I get the following response from Webmin:

"Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.
Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.
Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.
Error: Error informing the kernel about modifications to partition /dev/sr0p1 -- Invalid argument. This means Linux won't know about any changes you made to /dev/sr0p1 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.
Error: Failed to add partition 1 (Invalid argument)"

I tried logging in to Webmin as "root", as well as the username I use with Putty, and I get the same response.

I've also got 4 other drives (3@1TB, 1@2TB) that i've attempted to add to the LVM and I still get the same response. I'm sure I'm doing something wrong, do you have any suggestions?

Thanks so much for your help!

Well, I found a work-around!

I stole the command string that Webmin was trying to use and getting errors with, and pasted it into Putty. The first try I got an error so I added a "sudo" to the beginning and after typing in my PW, voila... took a few minutes but it configured it!

here is the commanc I used "sudo mkfs -t ext3 -q /dev/Media1-vg/UserData"

It is now mounted!

I'm moving on to partitioning the rest of my 5 TB. WHOO HOO!

Even though I found the answer on my own, I wouldn't have had a clue if it hadn't been for the HTKH site, so that for all great info.
