[SOLVED] Question about LVM

circus78 · 03-20-2014, 10:13 AM

Hi,
few days ago, I followed this tutorial to increase the size of the virtual disk of one of my VM (Vmware) with CentOS

http://kb.vmware.com/selfservice/mic...rnalId=1006371

now I realized that I have missed step g, h and i.
So, fdisk -l shows:

# fdisk -l

Quote:

Disk /dev/sda: 214.7 GB, 214748364800 bytes
255 heads, 63 sectors/track, 26108 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 13054 104751832+ 8e Linux LVM
/dev/sda3 13055 26108 104856255 83 Linux

Instead of:

# fdisk -l

Disk /dev/sda: 214.7 GB, 214748364800 bytes
255 heads, 63 sectors/track, 26108 cylinders

Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 13054 104751832+ 8e Linux LVM
/dev/sda3 13055 26108 104856255 83 Linux LVM

However, I successfully increased the partition and everything seems to work properly. There could be problems?
Thank you

Nope. The OS does not use the partition ID.

Nothing much cares about the partition types. LVM certainly doesn't; it runs on top of dm so the actual disk is hidden.

Hmmmm .... dunno about that. Last time I tried a pvcreate on a swap partition if refused to proceed. It specifically responded that swap (x'82') was unacceptable - regardless of whether it had been mkswap'd or not.

Was a year or two ago tho' ... (and yes, I was just curious to see what might work, and what might not)
