[Bug 581566] Re: udevd inotify_add_watch no such directory error for physical volumes

[mchk0123]

Some *possibly* better way to fix this error message :

* What I have done :

  - boot from the latest linux kernel version installed on my system
(2.6.32-32)

* The highly probable reason why this fix the error boot message :

  - I, previously, upgraded both dmsetup + dmraid + libdmraid and linux kernel (to the latest version
    available for my original lucid 10.04 ubuntu install)

  - *BUT* I switched back grub to booting, by default, with original
kernel version 2.6.32-21

  => So, my conclusion, is that there was a conflict between linux kernel (mainly dm-raid45 module ?)
        and dmraid tools / libs, leading to unpredictable situation

* Possible fix :

  - insure to have linux kernel and dmraid tools in compatible versions
    - eg. either original fresh installed versions
    - or all ones upgrade to latest possible version suitable for your ubuntu distribution

* Anyway, in my situation :

  - both have fixed all error message of type "inotify_add_watch ... no such directory"
  - *AND* the extra boot delay (traced by dmesg / syslogd)

* My software config :

  - Ubuntu 10.04 x64
  - Linux kernel 2.6.32-21 + 2.6.32-32
  - dmraid 1.0.0-rc16-4.1
  - libdmraid 1.0.0-rc16
  - dmsetup 2:1.02.39-1ubuntu4.1

* My hardware config :

  - AMD64 opteron
  - 1 internal PATA hdd
  - 1 faked RAID-0 of 2 SATA hdds with nvidia driver
  - 1 faked RAID-0 of 2 SATA hdds with jmicron driver

* Note :

  - I don't know if those solutions and my situation are exactly matching this bug report,
    but, if not, I'm sure my message will be redirected to a more suitable others bug report.
  - I hope not, because this was the top ranked bug report when I looked for
    "inotify_add_watch ... no such directory"

Title:
  udevd inotify_add_watch no such directory error for physical volumes

Status in dmraid:
  Confirmed
Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: udev

  udevd-work [91]: inotify_add_watch(6, /dev/sda1, 10) no such directory
  udevd-work [94]: inotify_add_watch(6, /dev/sdb4, 10) no such directory
  udevd-work [95]: inotify_add_watch(6, /dev/sdb5, 10) no such directory

  These are the partitions that are used as physical volumes in one
  physical volume  group that again is being used in one logical volume

  Sometimes the last error does not appear, but the other two are
  consistent with each boot.

  I ran ubuntu-bug udev, which information should be added to this
  message automatically
