My server is an 8.04 system which started it's sordid life as a 7.04 install from the base installer images.
The setup is rather customized at this point but here are the basics:
/dev/sda (generally) Internal Raid-5 Storage array: 3ware raid controller (mounted by uuid)
/dev/sdb (generally) Internal boot volume: SATA 80gb HDD (mounted by uuid)
/dev/sdc (generally) External semi-perminent USB storage: LaCie 1tb USB2 drive (mounted by uuid)
/dev/sdd (generally) External swapped-weekly USB storage: LaCie 1tb USB drive (same model) (mounted by device ID = /dev/sdd)
This system has a samba share setup pointing to an autofs mount point to mount the first 1tb drive (by uuid) whenever another server across the network accesses the samba share, and will disconnect / unmount the first disk after 60-120 seconds of the last file being closed by the client machines accessing the samba share. This works flawlessly so long as the second drive is not attached to the system. (I'm fond of this setup.) This is to make emergency grab-n-run possible in case of fire or such.
The second drive is configured to auto-mount by device name (/dev/sdd1) since there is a pool of these 1tb drives which will be rotated in and out. This device is the drive by which the first external USB drive is supposed to be copied for off-site storage on a weekly basis. (removed frequently, never the same UUID except when recycling the pool after some weeks).
Upon attaching the second drive to the system the ehci-hcd driver appears to freak out and "lose" one of the drives (sometimes both become unusable). I'm stumped as to whether this is because both the semi-permanent drive and the swapped drives are the exact same model (and lot) or not.
I have tried both drives individually (one at a time). Works fine.
I have tried both drives plugged into my laptop at the same time (started as 8.04 natively). Works fine.
I have tried two USB drives of different capacity (both LaCie units) at the same time. - Not working.
I have tried both drives plugged in, but in different areas (1 by keyboard connector, 1 on USB ports off of a different connector set in the expansion bays). Same issue.
I have tried both drives plugged into the same root hub on the back of the chassis. Same issue.
I have tried swapping cables around and out for different ones. Same problem.
Unloading the EHCI driver causes both drives to become visible and usable however, their bus numbers differ.
Basic Stats:
With both drives attached and EHCI loaded:
After unloading EHCI (modprobe -r ehci_hcd):
Once EHCI is unloaded both disks are perfectly accessible to the OS as sdc and sdd respectively.
Re-enabling EHCI goes like so:
It looks like it is attempting to detect the second disk and assign an address. However the lines for:
and the like seem to go on for some time.
Unloading all drivers for USB support and only loading the ehci_hcd driver (not the UHCI) provides the exact same setup (others had suggested that load-order for the hardware drivers may be to blame).
Also, I have attempted to turn off port standby using the information found here:
Any help or direction on how to get this working would be appreciated.
Thanks,
Robert
