    5757== Q6/ Does mondorescue handle LVM2 ? ==
    5858  ''Answer reported by Klaus Ade Johnstad <klaus_at_skolelinux.no>.''
    59   Short answer is Yes.
    60   Now if you encounter a problem with it, it might be due to the fact that older versions of mondorescue didn't support correctly the usage of
     59  '''Short answer is Yes'''.
     60  * Now if you encounter a problem with it, it might be due to the fact that older versions of mondorescue didn't support correctly the usage of
    6161  /dev/mapper/vg*. So you needed to adapt your /etc/fstab in order to make mondorescue happy, as here:
    6262
     
    7070  /dev/vg_system/lv_usr /usr ext3 defaults 0 2
    7171  /dev/vg_system/lv_var /var ext3 defaults 0 2
     72  }}}
     73
     74
     75  * Another problem, LVM pvcreate can't be done and exit with an error about filter.
     76  This is the same issue as reperted here : ''http://ubuntuforums.org/showthread.php?t=540752''
     77
     78  /etc/lvm/lvm.conf by default in Ubuntu and RHEL 4.0 (maybe others distro) contains the following line:
     79
     80  {{{
     81  filter = [ "a|/dev/hd[ab]|", "r/.*/" ]
     82  }}}
     83
     84  This either needs to be changed to:
     85
     86  {{{
     87  filter = [ "a|/dev/[hs]d[ab]|", "r/.*/" ]
     88  }}}
     89
     90  or
     91
     92  {{{
     93  # filter = [ "a|/dev/hd[ab]|", "r/.*/" ] (i.e. commented out)
    7294  }}}
    7395
     
    349371  You may be using a default minimum blocksize for RAM disks of 4k (Fedora kernel 2.6.18* and higher, e.g., RHEL5, ...) so try to add ramdisk_blocksize=1024 to your boot command at boot prompt of isolinux when booting your mondorescue media.
