Automounting in userspace with ivman

-spirit- · Posted: Thu Dec 30, 2004 3:19 pm Post subject: need help with ivman

hi, i need help with ivman, i can't get it working

hal & dbus works correctly, i had tried hal-device-manager, it's works perfectly.

my version :

sys-apps/dbus-0.22-r2
sys-apps/hal-0.4.2-r1

sys-apps/ivman-0.4_rc1

i have put ivman in debug, here the output for cdrom :

spirit: please try ivman-0.4_rc2 (it was added to portage very recently). Also, you have to be careful that, if you have an 'exec' command with '%m' in it, or an 'execdvd' command with or without '%m', they should always be within a 'Match' option. This is because, due to delays with HAL, it can take a few seconds for the mount point to appear for Ivman, and so Ivman will always wait a few seconds for these rules. Adding a USB stick actually adds several devices to the system (the stick itself, the emulated SCSI disk, the volumes on the emulated SCSI disk...) and if you have an execdvd or an exec with %m rule which is applied on each of these devices, it could cause significant delays.

Also, just so you are aware, with 0.4_rc2, you want to run one instance of Ivman as root to handle mounting volumes, and another as non-root to handle video DVD / audio CD autoplay etc. Everything tends to work much better this way.

If problems persist, please post your entire IvmConfigActions.xml file.

i had tried ivman-0.4_rc2, same problem

my IvmConfigActions.xml is the default config file.

i can't see where is the problem

Can you please post it anyway, just to be sure? From those log messages, it definitely looks like Ivman is trying to determine the mount point of every device, and with the default config file, this shouldn't be happening. Could you also please show the output of lshal for your usb pen and for your CD drive (with a CD in it)?

Alright, I guess I'll come for a bit of help as well. As has been said there's still some mehness to ejecting. However, I seem to have a problem with umounting itself.

For dvd's I can put a dvd in and eject it without playing it...however after playing it, it won't unmount and eject.

bash-2.05b# ivman
Ikke's Volume Manager, http://ivman.sf.net
hal_interface.c:41 (hal_device_added) New Device: /org/freedesktop/Hal/devices/block_DVDVolume

hal_interface.c:207 (hal_device_condition) /org/freedesktop/Hal/devices/block_DVDVolume received VolumeMount but no action taken

obiviously it gets mounted properly, however i have to manually umount it after watching and then ivman can't and or won't mount anything after that point. Even if its restarted.

Versioning info
sys-apps/hal Latest version installed: 0.4.2-r1
sys-apps/dbus Latest version installed: 0.22-r1
sys-apps/ivman Latest version installed: 0.4_rc1

Yes i'm currently upgrading to rc2 however I've noticed this since upgrading beyond the .2 version. So not sure whats going on but if you want more output please let me know.

tsunam: The problem with ejecting video DVDs after playing them seems to be entirely the fault of the DVD player software. They seem to lock the drive when they start playing, but not unlock it when done. Incredibly annoying, wouldn't you say? I've experienced the same problem...

I'm surprised that manually unmounting a device screws Ivman up. Have you tried just using the 'eject' command without unmounting first? This is what I've been doing, and Ivman seems to handle this fine (you might need to eject as root though, it's good to set it up to be sudo'ed). I actually bound this to a keyboard shortcut (using KHotKeys) because it annoys me so much.

Of course, even if this work-around does work, Ivman still shouldn't be screwed up by manually unmounting things, so I'll check it out :-)

The fact that Ivman won't mount stuff even after being restarted suggests that the bug is at a lower level (although it may still be triggered by Ivman doing something weird). Anyway, I'll try to get to the bottom of it. (by the way, you're almost certainly right and this bug will not be fixed in 0.4_rc2...)

Rohan28: thanks for the help. Using eject does allow ivman to continue to run afterwords...so thank you for that fix. Hopefully its not something caused by ivman. If you need help testing anything else since I've managed to find something strange once

let me know. P.S. as thought r2 still has the same issue if i do the former process to eject dvds.

rohan, here my IvmConfigActions.xml

rohan28 · Posted: Tue Jan 04, 2005 1:43 am Post subject:

spirit: OK, so it's definitely just the default. No problems there. And you are able to mount a CD manually with no trouble?

Well, try inserting a CD without Ivman running, do not mount it, then run 'lshal' and post the relevant output. There should be two relevant device entries, each with block.device = '/dev/hdc'.

Hello all,
thanks for this great utility! It already works fine for mounting my CDs. But I have this problem with my usb stick:

I'm using the default ivmconfigactions.xml, ivman-0.4-rc2, dbus 0.22-r3, hal 0.4.2-r1, udev 046 (050 didn't work too).
It seems to me that I need to tell hal/ivman that my usbstick is mountable? Btw, it's the same with my usb cardreader...

Perhaps someone around here can help me?
Thanks,

Joost

jwc: Please post the output of the command 'lshal' when your USB device is plugged in. When you plug in a USB stick, there are actually many devices which get added to the system; there's the raw USB device, a virtual SCSI interface (because USB drives use SCSI emulation), and then the emulated SCSI drive and the volumes on it, which is what you actually want to mount. The 'not mountable' messages you are seeing are directed towards the raw USB device and the SCSI interface, which is correct, because they are not mountable. (OK, so I'm putting it on my TODO list to change the code a bit to get rid of all these redundant warnings...)

If the volume on the USB stick appears as, eg, /dev/sda1, then look for a device entry in the output of 'lshal' where block.device='dev/sda1'. It should be named something like /org/freedesktop/Hal/devices/block_41D0-3F34 (where 41D0-3F34 is the volume's uuid). If there is no such entry, something is wrong with HAL or an underlying system (on a related note, I have actually only tested Ivman with udev 045); otherwise, something is wrong with Ivman and we'll have to investigate more :-(

Also, just to be sure... you're running Ivman as root, right? The default config when running as non-root is to not mount anything. Hey, maybe a man page for Ivman would be a good idea :-)

Hi,
thanks for your help!

Perhaps first of all relevant parts of my dmesg:

usb 3-1: new full speed USB device using uhci_hcd and address 2
usb 3-1: not running at top speed; connect to a high speed hub
Initializing USB Mass Storage driver...

Now the lshal stuff in fact doesnt't give me an entry for /dev/sda(1). If you wan't, hve a look for your self: http://www.wfeld.de/kde/hal.txt . I'll probably donwgrade udev to 045 and remove all old config stuff from /etc/udev/*.

Will probably be away all day,
bye,

Allright, sorry for wasting your time. Looks like my problem lies somewhere else. The note in dmesg on my usb stick only running full speed (and not high speed (USB 2.0)) made me suspicious and I rebooted without any usb-devices connected and tada! LEXAR_MEDIA got mounted. I suspect it's an issue with either my usb controller getting overloaded or the kernel usb-driver. I'll probably try some externally powered hubs if I get any somewhere.

Next problem is I plugged the stick and it didn't get umounted, but I'll have a look into it on my own first...

Bye, Joost

-spirit-: you might want to make that, "i thinks i 'll use submount until the next version of hal...." :-)

If your CD drive is /dev/hdc and you're only getting one HAL entry with block.device='/dev/hdc' when a CD is in the drive, it's a problem with HAL (or something below HAL). Actually, it'd be really nice to get a stable, working version of HAL, the current version seems to have quite a few bugs and inconsistencies across platforms :-(

Are there any plans to support MMC readers ?

As of version 2.6.10 the linux kernel supports MMC readers ( SD support being on the way ), device is /dev/mmcblk3p1 and I have such a card-reader in my Notebook and would like to have ivman automount inserted cards.

I hope, I'm right in this thread.

I just got ivman working, but my problem is that hald is spamming my kernel ring buffer (aka dmesg) with this message:
