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

[SteveRiley]

Each of those drives has a single partition. And none of them are in your fstab -- thats why they aren't mounting. Let's create some mount points, and then mount those drives to the points and take a look.

First the mount points:

sudo mkdir /mnt/sdb /mnt/sdc /mnt/sdd

Now mount them:

sudo mount /dev/sdb /mnt/sdb

sudo mount /dev/sdc /mnt/sdc

sudo mount /dev/sdd /mnt/sdd

Now, you should be able to open Dolphin and explore these drives. Can you?

[kdeuser]

reel@ReelBox:~$ sudo mkdir /mnt/sdb /mnt/sdc /mnt/sdd
[sudo] password for reel: 
reel@ReelBox:~$ sudo mount /dev/sdb /mnt/sdb
mount: /dev/sdb already mounted or /mnt/sdb busy
reel@ReelBox:~$ sudo mount /dev/sdc /mnt/sdc
mount: you must specify the filesystem type
reel@ReelBox:~$ sudo mount /dev/sdd /mnt/sdd
mount: /dev/sdd already mounted or /mnt/sdd busy
reel@ReelBox:~$

Drives sdb and sdd are fine just can not write to them and sdc still gives error.

[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

[kdeuser]

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.

[kdeuser]

I get the no file error :



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

[Teunis]

Try:

tail -f /var/log/syslog

[SteveRiley]

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.

[kdeuser]

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 ?

[Teunis]

I understand you want to work with a GUI but why use some app to change the ownership of drives when Dolphin is already available?

As root you open Dolphin,

kdesude dolphin

Find the drive and right click it, select properties and select Access.
Change (or add) access to the regular user (you I hope), done.
Oh yes, make sure you select Recursive (For all folders).

[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.

[Teunis]

Be careful when using Dolphin (and other editing facilities) as root because this will often change ownership from the regular user to root, is this possibly the reason behind your problem?

[kdeuser]

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.
