Minor number

[Yuri Fomin]

Hello.
I have 2 group files:
#root@xxxx:/> ll /dev/va_*/group
crw-rw-rw- 1 root sys 64 0x015000 Jan 27 21:22
/dev/va_aiv/group
crw-rw-rw- 1 root sys 64 0x010000 Jan 16 22:01
/dev/va_uos/group

Is it error? Is minor number 0x015000 = 0x010000 in such case?

Yuri,

Yes, you've got duplicate minor numbers. The minor number is the first two digits after the "x", so you've got two "01" minors.

Hi,

It is a duplicated minor number, check the example below.

# ll /dev/*/group
crw-r----- 1 root sys 64 0x000000 May 18 2000 /dev/vg00/group
crw-r----- 1 root sys 64 0x010000 May 18 2000 /dev/vg01/group

Yes you have two VGs with the same group ID.
The first two digits after x is the group ID. The rest should be zero.
You can probaly fix this by exporting the VG (with a map file). Create a new VG with a unique group ID and import it.

Regards,
Trond
