Quick query about LVM in 4.5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



        Howdy,

Does anyone know if anything has changed with the LVM system from CentOS 4.4 to CentOS 4.5?

I'm having kind of a funky issue.

I've mounted LVM partitions manually quite a few times and I've never had this issue before:

  --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol00
  VG Name                VolGroup00
  LV UUID                d6ksUI-Gha1-vC62-6eQS-2YtX-iQVJ-aMNkQC
  LV Write Access        read/write
  LV Status              available
  # open                 0
  LV Size                146.97 GB
  Current LE             4703
  Segments               1
  Allocation             inherit
  Read ahead sectors     0
  Block device           253:2

[root@localhost /]# mount /dev/VolGroup00/LogVol00 /old
mount: special device /dev/VolGroup00/LogVol00 does not exist
[root@localhost /]#

I'm not sure why, but when I do fdisk -l I get:

Disk /dev/dm-0: 160.0 GB, 160038912000 bytes
255 heads, 63 sectors/track, 19456 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

     Device Boot      Start         End      Blocks   Id  System
/dev/dm-0p1   *           1          13      104391   83  Linux
/dev/dm-0p2              14       19457   156183930   8e  Linux LVM

Now, /dev/VolGroup00/LogVol00 should be /dev/dm-0p2. Is there a new way to 'address' these partitions in 4.5?

Thanks,
-Drew
