Console DELETE command ???

[bombz]

Hello,

I have a folder on my disk2 drive (which has 2 empty sub folders) which I can not delete. I have tried deleting just via Windows (over the LAN). It will not delete the folders. I can re name the folders, but I would like it gone since they are not being used.

 

Is there a command from UnRAID console, to which I can perform this command / task, and finally be rid of these annoying folders/directories that are useless to me.

 

If I can not do it through console, would I physically have to pull the hard disk out, and boot it with unbuntu ? That was my next thought.

 

Thank you.

rm (Linux man page)

or

rmdir (Linux man page)

 

edit: I should add that rmdir directory will only work if the directory is empty.

 

You can go into the directory and check:

 

/disk2/directory >  ls -a

 

If there is a file that starts with a . such as ".cshrc" it may not show up without the -a switch.

 

The alternate method is

 

/disk2/ rm -r *

 

that should delete everything recursively from the current folder (in this example disk2)

I understand the command part, I was trying to mount the disk from UnRaid console, but it was not working, is there specifics to mount / delete ?

 

mount /disk2/ ??

 

what would be the process ?

 

i want to delete

 

disk2/-----/ 

 

(which has 2 sub directories in that folder that are empty)

You're not trying to delete disk2 are you? That is the drive itself which obviously can't be deleted. Taking a drive out of the array is not done by deleting it.

 

The disks are already mounted when the array is started. You will find disk2 by going cd /mnt/disk2

 

Try rm -r <dir_name>

Alternatively, cd into the directory and do rm -r * to delete all the contents of the directory first.

 

You do not want to mount a stopped disk and mess with it. That will break the parity protection.

 

You might need to do a file system check if you can't delete the files from the command line.

Ok, i did that command, and it thinks there is a .pdf file in one of the directories, but there is not. I am still trying to figure out why I can not remove it

 

cd /mnt/disk2/

 

disk2#: rm -r app

 

cannot delete app/pii/game_manuals/filename.pdf

no such file or directory

 

very strange :-s

 

I was going to do a clean power down of the server via GUI --- but it is stuck on trying to unmount disk2 now

 

 

Since the unmount was unsuccessful, I was forced to to a hard power down. The directories were not deleted, and now I have to let it complete its parity-sync ... I guess my next method is to pull the drive and boot with ubuntu, and try to delete the directory that way, then pop it back into my server, and do a new parity check, so it stays deleted.

How about rm -rf?

 

Be careful using this, it will forcibly remove what you tell it to do without confirmation, so make sure you've entered the folder you want to delete correctly.

 

ie:

 

cd /mnt/disk2

rm -rf app/

 

(this will remove EVERYTHING from the app/ folder).

It is stuck because you "cd'd" to it. It cannot unmount until you "cd" off of the disk you are trying to unmount.

 

All you needed to do is type

cd /

Since the unmount was unsuccessful, I was forced to to a hard power down. The directories were not deleted, and now I have to let it complete its parity-sync ... I guess my next method is to pull the drive and boot with ubuntu, and try to delete the directory that way, then it back into my server, and do a new parity check, so it stays deleted.

The other possibility is that corruption of the file system has caused the disk to be mounted as read-only.  It would then be impossibly to delete anything until it is corrected and mounted as read/write.

[lionelhutz]

You can do the same things with the disk in unRAID as you can in Ubuntu. unRAID is actually even better because you don't break parity.

 

There are a few possibilities for the failure to delete the directory;

The pdf file was open on a computer on your network - you need to close it.

The disk has corruption - test and repair as described here ->  http://lime-technology.com/wiki/index.php?title=Check_Disk_Filesystems

 

As Joe already posted, disk2 can not be unmounted when you are logged on and are cd'd to disk 2. You needed to log off or just go cd / to get away from that directory.
