Bug#440444: lvm2: lvrename fails: ioctl failed

[Bas Zoetekouw]

Package: lvm2
Version: 2.02.26-1+b1
Severity: important

When trying to rename an lv on my sid system, I get the following:

[root at cordelia]~# lvrename -d -v raid/mp3 raid/mp3old
    Checking for existing volume group "raid"
    Archiving volume group "raid" metadata (seqno 32).
    Writing out updated volume group
    Creating volume group backup "/etc/lvm/backup/raid" (seqno 33).
    Found volume group "raid"
    Found volume group "raid"
    Loading raid-mp3 table
    Suppressed raid-mp3 identical table reload.
    Suspending raid-mp3 (254:5) without device flush
    Found volume group "raid"
    Loading raid-mp3 table
    Suppressed raid-mp3 identical table reload.
    Renaming raid-mp3 (254:5) to raid-mp3old
  device-mapper: rename ioctl failed: Invalid argument
  Failed to rename raid-mp3 (254:5) to raid-mp3old
  Renamed "mp3" to "mp3old" in volume group "raid"
  WARNING: dev_open(/etc/lvm/cache/.cache) called while suspended

After this I get my prompt back, but any further lvm-related commands
hang in some kind of ininterruptable sleep (D+ state).  After a reboot
(hard reset, because proper shutdown of lvm in init 6 also hangs), the
renmae turns out to have succeeded after all, and everything works
fine.
