Drive has no mount point and other drives are read only.

[SteveRiley]

Yes, I see now that sdb and sdd are already mounted. I didn't look closely enough at your earlier screenshot and /proc/mounts. As to why they're mounting read-only, you'll need to look for diagnostic information. Do you see clues in /var/log/syslog and /var/log/syslog.1?

For sdc, let's see what happens if you tell it the file system type. According to your second screen shot, it's JFS. So the command is:

sudo mount -t jfs /dev/sdc /mnt/sdc

I was about to post when pc screen blacked out and `pc no signal` came up. Had n`t touched anything on keyboard , only typing this post.

There`s alot of reading there in those syslog files and went past the 100000 character mark. Do you still want those syslogs ?

The sdc disc failed again.

[SteveRiley]

Open two console windows. In the first, run

tail -f /var/syslog

It will display the last 10 lines of the file, and then simply wait. As new lines are recorded, they will appear on the screen. (tail -f is a very handy utility for watching files.)

In the second, try that mount command again. Did any new lines appear in the first window? If so, paste them here.

I get the no file error :



Edit : Just checked the syslog output on entering that mount command and no change in log file.

Thanks, Teunis. I have no idea why I was up so late last night answering questions!

[kdeuser]

Had some time yesterday , so i reinstalled - just one drive with the os.

Drives all mounted , fstab print below :



Still , it`s a half measure, as i can`t write to them.

[SteveRiley]

That's so weird. However, unless we can see some logs or other diagnostic information, there's no way for us to try to understand why they're mouning read-only.

I don`t want to lose my hard drives content but did try to reconfigure the drives this morning with a gui app named, pysdm.

Researching, it seems you could choose the drive , go to assistant, change privileges from read-only to read-write checking root and entering password.

I checked the root user box but no password box ? Course, nothing is that simple , damn - came close though.

So was thinking ( dangerous ) that maybe changing :

UUID=......................etc.................... ..default,nofail 0 3

In fstab to -

UUID=......................etc.................... ...rw 0 1

Would this work on all drives ?

[kdeuser]

Using sudo dolphin now for 4 out of 5 years since owning Reelbox htpc .

The only method i could find to write to the drives.

Tried sudo nautilus which gave me a menu of drives , clicked on a drive , properties, changed read to rw but could not find recursive mode ?

Bottom line , went to save but still read only.

Lets call this one , at least i can ( write to ) with kdesudo dolphin.

I would like to mark this post as solved but in reality this is a workaround i guess.

Thanks to everyone who helped though.

Hi , hope you all had a great festive season.

Back again with this funny 3t drive and it´s unmounted .

Exactly the same problem as before.

Did n´t use the ´tail´ command as the drive mounted. Here are the 2 terminal readouts.

Console 1 :



Console 2 :



There´s also this error :



Hope this helps.

You can't mount a drive, you have to mount the filesystem. In this case, your filesystem is on sdc1 not sdc.

Try mounting /dev/sdc1 instead.

[kdeuser]

Tried that new format but the drive´s not mounting.

[SteveRiley]

You're missing a space in the command. You typed

sudo mount -t jfs /dev/sdc1/mnt/sdc1

when it should be

sudo mount -t jfs /dev/sdc1 /mnt/sdc1

Also, the directory sdc1 needs to already exist in /mnt. You can't mount a file system to a nonexistent directory.

[kdeuser]

Thanks a small error there but still not mounting :



Drives sdb and sda are fine it´s only sdc which does not want to mount.

Just refuses to make a mount point ?

[oshunluvr]

No it's not "refusing" to make a mount point, you've typed it wrong again.

This time you created (or had) a mount point - /mnt/sdc - and then attempted to mount to - /mnt/sdc1 - which doesn't exist because that's not the mount point you created.

Either create the mount point as /mnt/sdc1 as Steve said in his last post, or use one that already exists - /mnt/sdc. For some reason, you've assumed the mount point label (folder name) must match the partition label. The system does not care what you mount or where you mount it, but it can't mount devices that don't have filesystems (/dev/sdc) or mount to locations that don't exist (/mnt/sdc1).

Your computer isn't going to read your mind or guess at what you want. It's going to do (or try to do) EXACTLY what you type. Therefore you must type EXACTLY what you want it to do.

As Steve and I have said; Use /dev/sdc1 as the mounting device because /dev/sdc does not have a filesystem on it and either create /mnt/sdc1 or use /mnt/sdc - doesn't matter which. Either of these commands should work;

sudo mount -t jfs /dev/sdc1 /mnt/sdc

or

sudo mkdir /mnt/sdc1; sudo mount -t jfs /dev/sdc1 /mnt/sdc1
