Topic: Can't mount USB disk

[alext]

I've just installed and configured a fresh copy of SME 9.0 on to a secondary server.

Prior to the installation the server had SME 8.1 and I backed up a bunch of files onto a USB disk.

When I plugged in the USB disk to the new server it did not appear to auto-mount so, following the advice in the "USBDisks - How-to", (as I had also done on the 8.1 installation), I executed the mount command to see if I could see reference to the USB drive.

I could see nothing related to USB so then I used the following suggested command to search the message file:
   egrep "(kernel|fstab|scsi).*(usb|USB)" /var/log/messages

I scanned through the output but couldn't find any reference such as:
   ...added mount point /media/usbdisk1 for /dev/sdd1

Have I missed something out on my installation or is this "How-to" only related to pre-9.0 installations?

Thanks in advance for any help.

connect as root

Code: [Select]

tail -f /var/log/messages

plug in the usb disk and see if something appears.. if so, report here, thank you
btw, what kind of usb disk are we talking about? some external enclosures (3.3") sometimes are problematic

Hi Stefano,
I ran the "tail" command, connected the USB disk as requested and watched: nothing changed.

Output is as follows:

Code: [Select]

[root@gandalf ~]# tail -f /var/log/messages
tail: inotify cannot be used, reverting to polling

I then ran the "tail" command again, (after I had plugged in the USB disk), but the output was the same.

The physical disk is an ExcelStor J240, (not a very big disk as it only needs to bakup my ibays).

The USB connection is a temporary unit that I use to connect any IDE or SATA device via USB for inspection/maintenance/recovery etc. The unit is a USB 2.0 to SATA/IDE Cable manufactured by Maxxtro.
I use this device on many systems, (Linux and Windows), including this SME box.
In fact I used exactly the same setup on the V8.1 system that was installed previously on this server in order to create the backup on the ExelStor disk.

Thanks for your help and I hope you can spread some more light on the problem.

Cheers

IMO your sata to usb cable has a problem.. repeat what I suggested you using, for example, an usb key..

if it works, the issue is with your adapter, if not, the problem is with your (server) HW

Thanks Stefano.
I was coming to the same conclusion so I plugged in another external HDD, (Maxtor OneTouch), which has partitions formatted in NTFS and FAT32.

This time I got a result on the "tail" command:

If I am correct, this USB disk now shows up as sdb1

I just have to find a new way to attach my physical backup disk.

Many thanks for your help.
