Mounting Second Ext3 HDD

metallica1973 · 02-22-2008, 11:04 AM

I pulled another hdd from another cpu with a LVM Volume. It has a lot of data on it that I need. my current system has is using ext3 file system. How can I mount an LVM volume from an old hdd to my new machine that has a ext3 file system on it? It is being seen as hdb:hdb1,hdb2,hdb3. I tried

PHP Code:



mount  /dev/VolGroup00/LogVol00 /media/oldhdd/

neither worked. help

Here is a snippet of dmeg:

PHP Code:



   ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:DMA

Wow I made a mistake. It is a LVM:

PHP Code:



Disk /dev/hdb: 120.0 GB, 120034123776 bytes 
255 heads, 63 sectors/track, 14593 cylinders 
Units = cylinders of 16065 * 512 = 8225280 bytes 
 
   Device Boot      Start         End      Blocks   Id  System 
/dev/hdb1   *           1          25      200781   83  Linux

/dev/hdb3             153       14593   115997332+  8e  Linux LVM

I ran pvs:

PHP Code:



 PV         VG         Fmt  Attr PSize   PFree  
  /dev/hdb3  VolGroup00 lvm2 a-   110.59G 32.00M

and lvdisplay

PHP Code:

and then tried:

PHP Code:



mount  /dev/VolGroup00/LogVol00 /media/oldhdd/

to get:

PHP Code:



mount: special device /dev/VolGroup00/LogVol00 does not exist

what next?

I was able to figure out how to mount a secondary hdd that has a LVM volume to an existing system that is running ext3. Here we go: I used several utilities for LVM such as pvscan,vgdisplay,lvdisplay,pvs,vgchange:

I used pvscan to give me my volume name:

PHP Code:



  PV /dev/hdb3   VG VolGroup00   lvm2 [110.59 GB / 32.00 MB free]
  Total: 1 [110.59 GB] / in use: 1 [110.59 GB] / in no VG: 0 [0   ]

for more info I used vgdisplay

PHP Code:



  --- Volume group ---
  VG Name               VolGroup00
  System ID             
  Format                lvm2
  Metadata Areas        1
  Metadata Sequence No  6
  VG Access             read/write
  VG Status             resizable
  MAX LV                0
  Cur LV                5
  Open LV               1
  Max PV                0
  Cur PV                1
  Act PV                1
  VG Size               110.59 GB
  PE Size               32.00 MB
  Total PE              3539
  Alloc PE / Size       3538 / 110.56 GB
  Free  PE / Size       1 / 32.00 MB
  VG UUID               p6PTty-7HUX-tJFD-ucRX-rxkZ-TEo3-D98mom

more info pvs

PHP Code:



  PV         VG         Fmt  Attr PSize   PFree 
  /dev/hdb3  VolGroup00 lvm2 a-   110.59G 32.00M

but the most handy was the lgdisplay which give me all the volume information that I need.

PHP Code:



    --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol00
  VG Name                VolGroup00
  LV UUID                5rgQoX-V80q-oPc0-OHdi-Sm94-xAqI-GoFA3B
  LV Write Access        read/write
  LV Status              available
  # open                 0
  LV Size                9.75 GB
  Current LE             312
  Segments               1
  Allocation             inherit
  Read ahead sectors     0
  Block device           253:0

  Block device           253:1
   
  --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol03

  LV Write Access        read/write

  # open                 0
  LV Size                19.53 GB
  Current LE             625
  Segments               1
  Allocation             inherit
  Read ahead sectors     0
  Block device           253:2
   
  --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol02
  VG Name                VolGroup00
  LV UUID                F4tZw4-6Bvw-DOto-cgDL-ylMO-30hh-S1ndms
  LV Write Access        read/write
  LV Status              available
  # open                 0
  LV Size                29.28 GB
  Current LE             937
  Segments               1
  Allocation             inherit
  Read ahead sectors     0
  Block device           253:3
   
  --- Logical volume ---
  LV Name                /dev/VolGroup00/LogVol01
  VG Name                VolGroup00
  LV UUID                NQ6ewo-5Nj3-q2YK-Ttr6-FaTK-oWKY-KzOlv1
  LV Write Access        read/write
  LV Status              available
  # open                 0
  LV Size                29.28 GB
  Current LE             937
  Segments               1
  Allocation             inherit
  Read ahead sectors     0
  Block device           253:4

and finally vgchange which changes the attributes of a volume:

PHP Code:



vgchange -ay

and then you have to mount the volume that you need and in my case it was
/dev/VolGroup00/LogVol04

PHP Code:



 mount /dev/VolGroup00/LogVol04 /media/oldhdd/

I used this reference link:

I hope this help.
