LVM extend volume problem

Hello,

I'm wondering if anyone here might have time to help me out with a problem I'm having. This weekend, while trying to extend a logical volume on a RedHat Enterprise server (ES release 4 Nahant update 3), I get the following error:

[root@sawara ~]# lvextend -L+10G /dev/VolGroupFiles/public
Extending logical volume public to 20.00 GB
device-mapper: deps ioctl failed: Invalid argument
_deps: task run failed for (253:5)
Failed to add device (253:5) to dtree
Failed to suspend public

The same error occurs with all logical volumes. As well, I get a similar error when trying to remove a volume:

[root@sawara ~]# lvremove /dev/VolGroupFiles/test
Do you really want to remove active logical volume "test"? [y/n]: y
device-mapper: deps ioctl failed: Invalid argument
_deps: task run failed for (253:9)
Failed to add device (253:9) to dtree
Unable to deactivate logical volume "test"


Any insight as to how I might be able to resolve this would be very, very much appreciated.

Thanks in advance.

Regards,

Greg

 

Are there any errors in your logs?

Maybe it's a broken hard drive?

 

Hi,

Thanks for responding.

Looking in /var/log/messages all I'm seeing that may pertain to this is:

messages.2:Nov 22 13:06:30 localhost kernel: device-mapper: one of name or uuid must be supplied, cmd(11)

All hard drives seem to be working fine in this server.

Any ideas?

Thanks again.

how about

Code:

lvextend -L +10G /dev/VolGroupFiles/public

?

 

Hi sjau,

Thanks for posting. I've actually tried that, and also:

lvextend -L30G /dev/VolGroupFiles/public

and receive the same error in all cases.

Another thing that I noticed today - when creating a new lv, the file /dev/mapper/VolGroupFiles-test is created but the link /dev/VolGroupFiles/test is not.

Any further suggestions would be very much appreciated.

how about:

Code:

lvextend -l +23445 /dev/.../....
lvextend -l +243 /dev/.../....

that should expand it to full size.
