 |
|
Hi
Im experimenting with LVM2 and its Logic Volumes. Whenever i make some partitions with parted or cfdisk in a LV, i cant see the device node that should be created because of this. Like:
/dev/mapper/vg-test <-- LV block device
/dev/mapper/vg-testp1 <-- partition 1
/dev/mapper/vg-testp2 <-- partition 2
I've tried the same on some other distributions. On some distributions both parted and cfdisk tells me to reboot the kernel, because it cant signal it to update the nodes.
Is there a tool / feature / command that forces the kernel or a userspaceprogram to update these nodes? |

I don't know if LVM uses a special command, but this works on regular devices.
| Code: | # blockdev --rereadpt /dev/mapper/vg-test
# dmesg | tail |

hmm doesn't seem to work. If i run:
| Code: | | blockdev -v --rereadpt /dev/mapper/vg-test |
i get:
| Code: |
BLKRRPART: Invalid argument
reread partition table failed.
|
there is no errors/warning entries in dmesg after i run this command. |
