[sisyphus] Сломался LVM2?

[Eugene Prokopiev]

Здравствуйте!

На сегодняшнем Сизифе:

# lvscan
   ACTIVE            '/dev/system/root' [2.00 GB] inherit
   ACTIVE            '/dev/system/home' [1.00 GB] inherit
   ACTIVE            '/dev/system/var' [1.00 GB] inherit
   ACTIVE            '/dev/system/data' [65.00 GB] inherit
# /sbin/lvcreate -L1000 -s -nhomebackup /dev/system/home
   Symbolic link /dev/mapper/system-home not created: file exists
   Failed to create symlinks for home.
   Failed to suspend origin home
# lvscan
   ACTIVE            '/dev/system/root' [2.00 GB] inherit
   ACTIVE            '/dev/system/home' [1.00 GB] inherit
   ACTIVE            '/dev/system/var' [1.00 GB] inherit
   ACTIVE            '/dev/system/data' [65.00 GB] inherit
   ACTIVE            '/dev/system/homebackup' [1000.00 MB] inherit
# mount /dev/system/homebackup /mnt/backup
/dev/system/homebackup: Invalid argument
mount: /dev/system/homebackup: can't read superblock
# lvremove /dev/system/homebackup
Do you really want to remove active logical volume "homebackup"? [y/n]: y
   Logical volume "homebackup" successfully removed

Отчего lvcreate приводит к таким странным результатам?
