 Posted: Sat Dec 03, 2005 8:15 pm Post subject: USB Hard disk very slow |
 |
|
I have a Freecom external USB hard disk. Under Mandriva, it gives good performance (hdparm -tT buffered disk read speed ~22MB/s), while under Gentoo (my main and preferred OS) I only get:
/dev/sda:
Timing cached reads: 1688 MB in 2.00 seconds = 842.02 MB/sec
Timing buffered disk reads: 4 MB in 4.35 seconds = 942.62 kB/sec
This is using exactly the same system (laptop and connected devices).
From /proc/bus/usb/devices:
| Quote: | T: Bus=02 Lev=02 Prnt=03 Port=00 Cnt=01 Dev#= 4 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=07ab ProdID=fc05 Rev= 2.40
S: Manufacturer=Freecom Technologies
S: Product=Classic SL Hard Drive
S: SerialNumber=DEF10A8FCD5E
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 2mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=86(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=81(I) Atr=03(Int.) MxPS= 2 Ivl=12ms
|
There are some worrying looking lines in the dmesg output, such as:
| Quote: | usb 2-3.1: new full speed USB device using ohci_hcd and address 4
usb 2-3.1: not running at top speed; connect to a high speed hub
|
(There are a few entries like this, not sure which, if any, applies to this device)
So it looks like Gentoo is not running it at maximum speed - even though Mandriva does (exactly the same hardware configuration, literally just rebooted).
Any ideas, please?

Sorry - I should have mentioned drivers in my initial post, according to lsmod, the following are currently loaded (among others):
| Quote: | ehci_hcd 31816 0
ohci_hcd 21284 0
uhci_hcd 32144 0
usb_storage 70752 0
usbcore 115996 7 sl811_hcd,ohci_hcd,uhci_hcd,usb_storage,usbhid,ehci_hcd
usbhid 43040 0

Thanks

Similar problem:
| Code: | Dec 13 16:45:47 wideload usb 3-1: new full speed USB device using uhci_hcd and address 3
Dec 13 16:45:48 wideload ub(3.3): GetMaxLUN returned 0, using 1 LUNs
Dec 13 16:45:49 wideload uba: uba1
Dec 13 16:45:56 wideload fstab-sync[11016]: added mount point /media/usbdisk for /dev/uba1
|
and
| Code: |
/dev/uba1:
Timing buffered disk reads: 2 MB in 81.78 seconds = 25.04 kB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
|
The same device in another Gentoo computer gets orders of magnitude faster performance... |

Has anyone got any ideas? I've just bought an iPod and exactly the same thing happens - it seems to be running only at USB 1.1 speed.
I'd really appreciate any help anyone can give

Just a thought,
What mount options are the devices being mounted with?
Seem to recall to problems on USB devices (esp. with newer kernel) if the 'sync' option is set for the mount, can't remember if it needs an 'async' option passing, or just not passing 'sync' - something to do with sync-ing writes - I've only experienced it on smaller USB flash sticks, but it certainly has sorted out the problem for me.
Also what are the other drive settings (hdparm -iI <disknode> - if memory serves), don't really have much experience with USB drives though.
Regards,
Ryan |

I thought | Code: | ohci_hcd 21284 0
uhci_hcd 32144 0
|
were two different usb 1.1 drivers and you probably only need one.
Don't know why both are loaded, could be causing a conflict or using wrong one? |

I collected info from the "good" system.
| Code: | spooky ~ # lsmod | grep hci
ohci_hcd 21764 0
ehci_hcd 35272 0
uhci_hcd 34000 0
ohci1394 36148 0
ieee1394 103544 2 eth1394,ohci1394
usbcore 125696 9 snd_usb_audio,snd_usb_lib,ohci_hcd,ehci_hcd,usb_storage,usbmouse,usbhid,uhci_hcd |
Since both uhci and ohci are loaded I don't think it causes a conflict.
I get: | Code: | /dev/sde1:
Timing cached reads: 1376 MB in 2.00 seconds = 686.58 MB/sec
Timing buffered disk reads: 2 MB in 4.12 seconds = 496.57 kB/sec |

I'll edit this with the same data from the "bad" system (my laptop). The above (my desktop) is quite different than the laptop, for reasons I haven't yet been able to research. |

Looking at your Spd value below ("Spd=12" should be "Spd=480"), and the ("MxPS=64" should be "MxPS=512") values, it really does look like your drive's not taking advantage of the ehci_hcd module:

I'd try to play around with rmmod'ing uhci_hcd (I think you said it was there?). I just fixed the same problem by building and loading ehci_hcd.
Good Luck,

I tried rmmoding uhci_hcd, but on my system it doesn't recognize anything then because the bridge uses that driver. Rmmoding ehci_hcd had no effect.
It seems like there is a bug in uhci_hcd for this chipset, maybe? I say that because same kernel and everything and same camera in another computer works fine...
Btw, why does this computer get uba1 and the other one get sde1? |

Now I can't even get the disk to mount, after a major update. Using kernel:2.6.16-gentoo-r6.
| Code: | May 9 02:56:47 wideload usb 5-5: new high speed USB device using ehci_hcd and address 2

May 9 02:56:48 wideload uba: uba1

May 9 02:56:48 wideload usbcore: registered new driver usb-storage
May 9 02:56:48 wideload USB Mass Storage support registered. |
But gnome-volume-manager can't mount it because it says uba1 isn't in fstab/mtab. Huh? Do I have the kernel misconfigured? |

You probably have the Low Performance USB driver in your new kernel.
| Code: |
Device Drivers --->
Block Devices --->
< > Low Performance USB Block driver
|
That's also why the devices are now showing up as /dev/ubx instead of /dev/sdax.

Probably your fstab points to /dev/ubX which doesn't exist anymore. Check your /dev/ for sdX and see if that solves your problem.
PS: The info troymc gave is very helpful I had similar problems with a usb pen, showing up as /dev/uba1 and getting slower speeds.

Yes, it turns out that disabling the CONFIG_BLK_DEV_UB option fixed the UBA thing. (The help for that option should have clued me in!). But I still can't get it to automount. Now I get: | Code: | May 9 05:34:55 wideload usb 5-1: new high speed USB device using ehci_hcd and address 5

Show us your /etc/fstab file.
Do you not have an entry for sda1?

No, because GVM (gnome-volume-manager) is supposed to add it for me.
EDIT: DOH!!! Never mind. I just discovered that I need to be in the plugdev group for this to work..... It works now. |

Somebody solved the problem?
I've an external 400gb hd connected with USB2.0
I get about 1MB/s with hdparm on that HD.
When I tranfer big files (about 600MB) I see a strange thing: after the first 50-100mb it stop for about 30-40 seconds (The kernel is in IOWait state) and then resume the trasfer of other 50-100mb and so on.
I don't see any error/warning in the kernel log during the transfer.

No, it seems like your drive is connected to USB1.1 bus, which has maxium speed about that 1MB/s

I had the same problem with only getting usb1 speeds on my usb2 drives and flash disk.
Fixed it by removing the sync option in my /etc/fstab file. It has something to do with the new kernel, not exactly sure from which kernel onwards. but pretty recent I would say. drjones69 did mention removing the sync option too. Try removing sync options al together instead on async?
Hope this helps |

I've an external 400gb hd connected with USB2.0
I get about 1MB/s with hdparm on that HD. |
No, it seems like your drive is connected to USB1.1 bus, which has maxium speed about that 1MB/s |
Yes, I discovered it some minutes after posting the message.
I'll try to buy an UBS 2.0 hub |
