 Posted: Tue Feb 05, 2008 6:54 pm Post subject: stuck on USB drives [SOLVED] |
 |
|
This problem has kept me googl'ing for a solution for a long time 
- can mount any USB drive
- can umount
- can do some basic file operations
But:
- after a lot of data traffic, USB drive will simply not respond anymore
- at that point, I cannot umount it anymore
- umount will be stuck and cannot stop it (ctrl+c) anymore
- any application trying to access it will freeze
- in the end, I have to reboot my systeem (reboot linux ?? NOOOOOO)
Can anyone point me in the right direction ?

I have no idea, and will probably continue to have no idea, but you should post an "emerge --info".
...then some name-taking, ass-kicking l33t might wander by fix it by blinking hard.

Is it a hard-disk USB drive?
Some hard-disk USB drives auto spin-down after a period of idle time and the kernel doesn't know to spin it back up. The Seagate Freeagent series seems especially troublesome in this regard.
Creating the following udev rule seems to have helped me, at least with the Freeagents. Tweak it as needed for your own device.
In /etc/udev/rules.d/99-freeagent.rules | Code: | ACTION=="add", SUBSYSTEM=="scsi_device", ATTRS{vendor}=="Seagate*", ATTRS{model}=="FreeAgent*", \
RUN+="/bin/sh -c 'echo 1 > /sys/class/scsi_disk/%k/allow_restart'" |
(Addendum: if this does not solve your problem, please post the output of dmesg | tail -50 ) |

It happens with pen-drives also.
I found that it must have something to do with the cache/buffer. If I unmount and remount each minute, I can keep using the thing. As you know, umount flushes the drive.
Maybe I should try some mount options, like :
| Code: |
async All I/O to the file system should be done asynchronously.
atime Update inode access time for each access. This is the default.

This is what dmesg says after I plugged in my USB stick :

a simple 'sync' would do the same

I always see those messages, but I never experienced the problem you mention.

I've had the same thing happen with USB hard drives since upgrading to gentoo-sources-2.6.24, with the additional problem that my USB keyboard stops working when a write operation gets stuck. Yesterday I booted into a gentoo-sources-2.6.23-r6 kernel, and everything worked fine.
Interestingly, I was able to copy large files successfully to my thumb drive. I don't know if that's because it's slower, or because it's formatted with FAT32 while my hard drives are formatted with NTFS (and accessed via ntfs-3g).
When I get a chance, I'll try a vanilla 2.6.24 kernel. |

Lawrence thanks for the info.
I'll try another kernel in the weekend. I tend to make a mess of my kernel configs 
Currently using 2.6.18-gentoo-r4 x86_64

This might be related:
My swap almost filled up last night, and if that happens I usually run "swapoff -a" (followed by swapon -a) to clear the swap. Usually it takes about 10 seconds to clear swap. Now I'm using 2.6.24, and when I ran "swapoff -a" it took about 15min to clear the swap.
Now, I have no idea why this happens, but it could be that if you (ug) what long enough (i.e. 15 to 45min), your usb might finish whatever operation it's stuck in and allow you to unmount it gracefully.
I'll try messing around with a key on my home machine tonight and see if I get hit by the same thing as you have.

changing kernel from 2.6.18 to 2.6.23 did not help 
using sync in between each file however does do the trick, but is so awkward.

I can't reproduce the prob on my machine in 2.6.24, and zebrapad isn't running it anyway, so it's probably not related.
Do you have a different brand of USB key you can try? I'm stumped.
If it helps, here's what mine looks like when I plug in a USB:
| Code: | usb 1-4.2: new high speed USB device using ehci_hcd and address 11
usb 1-4.2: configuration #1 chosen from 1 choice
scsi 14 : SCSI emulation for USB Mass Storage devices
scsi 14:0:0:0: Direct-Access Kingston DataTraveler 2.0 6.16 PQ: 0 ANSI: 0 CCS
sd 14:0:0:0: [sde] 2004991 512-byte hardware sectors (1027 MB)
sd 14:0:0:0: [sde] Write Protect is off
sd 14:0:0:0: [sde] 2004991 512-byte hardware sectors (1027 MB)
sd 14:0:0:0: [sde] Write Protect is off
sde: sde1
sd 14:0:0:0: [sde] Attached SCSI removable disk
sd 14:0:0:0: Attached scsi generic sg6 type 0 |

[SOLVED]
JeliJami gave me the idea to use the command sync,
and it appears that it also is a mount option.
So I added an entry to my fstab and so far, I can transfer data without worries!
| Code: | | /dev/sdb1 /mnt/xsdrive vfat noauto,sync,exec,user 0 0 |
Many thanks rlittle, JeliJami and Lawrence for helping me fix this!
I LOVE GENTOO

I'm glad to hear you've solved your problem. I still have a similar problem with 2.6.24.1. I tried various 2.6.24-rc kernels to try to narrow it down, but it never occurs during testing. I can even switch back to 2.6.24 or 2.6.24.1 while I'm trying to reproduce it, and suddenly the problem won't occur. |

Just to tie up my part of this thread, I'll quote this portion of the announcement for the latest NTFS-3G:
| Quote: | Thanks to our Gentoo users and Miklos Szeredi, it was found out recently
that the FUSE kernel module used from the FUSE software packages (Gentoo
default) with the 2.6.24 Linux kernels can lockup the system.
Solution: use the FUSE kernel module included in the 2.6.24 Linux kernel
(drawback: NTFS can't be NFS exported). |
I swear I tried this and it didn't work, but I probably just screwed something up. Now a gentoo-sources-2.6.24-r2 kernel with the built-in FUSE module works perfectly for me. |
