Cannot access 5big network 2

I remember that some usb disks are not detected if the usb.ids database is not updated.

First, can you check if you have the file /usr/share/usb.ids ?

Nope. Nothing in /usr/share.

Code: Select all

root@fvdw-sta-kirkwood:/lib # cd /usr
root@fvdw-sta-kirkwood:/usr # cd share
root@fvdw-sta-kirkwood:/usr/share # ls
root@fvdw-sta-kirkwood:/usr/share #

I don't think the usb.ids file is the problem. There is no trace of an unknown usb device in the kernel log.

Are you sure about your USB cable? It's not a 'power only' cable?

How about eSata?

[Jocko]

so upload this file after unzipping it in this folder.
(the file doesn't require special permission)

Then try to unplug and plug again the udb drive. Post the dmesg content and see if new devices are available in /proc/partitions.

I am sure the cable is ok. Connected it first to my laptop. Had a NTFS partition of 2TB. Deleted the partition and connected it to the Lacie.

Sorry, no eSata available.

I did notice one thing. When I rebooted the Lacie whilst the usb disk connected I couldn't start the RAID. I rebooted again without the usb disk, mounted the RAID and then connected the usb disk.

Indeed I forgot this point.

No change in dmesg and no change in /proc/partitions :-(

I rebooted, uploaded mdadm, started the array, connected the usb disk and started udevstart.
Previously I uploaded mdadm, udevstart while the usb disk was connected and the array couldn't start.

I think that the right sequence is:
1/ upload mdadm, udevstart
2/ run udevstart
3/ plug the usb disk
4/ restore the raid

I think that you can also switch the steps 3 or 4

OK. Maybe somehow the USB disk is only detected on boot. In that case it can shift the disk devices, which means the raid array has to be assembled from other devices.
Can you redo that, and post the output of

Code: Select all

cat /proc/partitions

OK, give me a second.
