vgcreate error

amir syafiq — Fri, 20 Mar 2009 01:44:55 GMT

Im using RP3410 with HPUX 11.11.

Command that I used to create VG:-

#ioscan –fnC disk

#vgdisplay –v vg01
vgdisplay: Volume group "/dev/vg01" does not exist in the "/etc/lvmtab" file.

ALL look ok

Then I used pvcreate with option f (force)

# pvcreate -f /dev/rdsk/c3t2d0
Physical volume "/dev/rdsk/c3t2d0" has been successfully created.

#mkdir /dev/vg01
#mknod /dev/vg01/group c 64 0x010000

# vgcreate /dev/vg01 /dev/dsk/c3t2d0
Warning: Max_PE_per_PV for the volume group (65535) too small for this PV (71525).

Increased the number of physical extents per physical volume to 65535.
vgcreate: Volume group "/dev/vg01" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the
extent size or decrease max_PVs/max_LVs and try again.

# vgcreate -s 32 /dev/vg01 /dev/dsk/c3t2d0
Increased the number of physical extents per physical volume to 8940.
vgcreate: Volume group "/dev/vg01" could not be created:
The path does not specify a valid physical volume.

That the error, try remove the device file using command rmsf , delete the vg01 folder, rename lvmtab file to lvmtab.bak, vgscan –v and etc. the error still same.

Hi

Please repeat pvcreate -f /dev/rdsk/c3t2d0 again
mkdir /dev/vg01
ll /dev/*/group
if you found group file for vg02 remove that
mknod /dev/vg01/group c 64 0x010000
vgcreate -s 32 /dev/vg01 /dev/dsk/c3t2d0

Hi,

Where is group file for vg01?

After creating the /dev/vg01 directory create group file before create the vg

#mknod /dev/vg01/group c 64 0x010000

hi amir

>>Warning: Max_PE_per_PV for the volume group (65535) too small for this PV (71525).
Using only 65535 PEs from this physical volume.

here is your problem. Because of your max pe parameter is set to low, it can't be expecting more than its setting value.

try to create another vg and create the file systems.

Re: vgcreate error

amir syafiq — Fri, 20 Mar 2009 08:03:02 GMT

now creating new volume group no problem. but after create the VG:-

# vgcreate -s 16 /dev/vg01 /dev/dsk/c3t2d0
Increased the number of physical extents per physical volume to 17881.
Volume group "/dev/vg01" has been successfully created.
VGRA appears corrupted

when i try to deactivate or reboot the VG01 can't start.

# pvcreate -f /dev/rdsk/c3t2d0
Physical volume "/dev/rdsk/c3t2d0" has been successfully created.

#vgcreate â s 16 /dev/vg01 /dev/dsk/c3t2d0
Volume group /dev/vg01 succerfully created
VGRA corrupted

# vgchange -a n vg01
Volume group "vg01" has been successfully changed.

# vgchange -a y vg01
vgchange: Couldn't activate volume group "vg01":
Quorum not present, or some physical volume(s) are missing.

Sharma Sanjeev — Fri, 20 Mar 2009 08:12:52 GMT

Hi Amir

Activate your VG with no quoram

vgchange -a y -q n /dev/vgname....

than check vgdisplay -v vgname and look for the disks in this VG.

Ganesan R — Fri, 20 Mar 2009 08:28:23 GMT

Hi,

Better remove the VG and recreate it to get out of the mess.

Just export the VG to remove the configuration entirely from the system

#vgexport -v vgname

Now create freshly.

Re: vgcreate error

amir syafiq — Fri, 20 Mar 2009 09:00:23 GMT

i remove all vg01 config, device file c3t2d0,rename /etc/lvmtab file and create vg again.

# pvcreate -f /dev/rdsk/c3t2d0
Physical volume "/dev/rdsk/c3t2d0" has been successfully created.

#mkdir /dev/vg01

#mknod /dev/vg01 /dev/dsk/c3t2d0

#vgcreate â s 16 â p 126 â e 65535 /dev/vg01 /dev/dsk/c3t2d0
Volume group /dev/vg01 succerfully created
VGRA corrupted

# vgchange -a n vg01
Volume group "vg01" has been successfully changed.

# vgchange -a y vg01
vgchange: Couldn't activate volume group "vg01":
Quorum not present, or some physical volume(s) are missing.

# vgchange -a y -q n vg01

Duncan Edmonstone — Fri, 20 Mar 2009 09:25:19 GMT

at this stage I would be thinking:

a) patches - do you have all the latest LVM patches installed?
b) bad disk? do you have another disk you can try the operation on?

Hi Amir

Just looked at you previous reply

#vgcreate Ã¢Â Â s 16 Ã¢Â Â p 126 Ã¢Â Â e 65535 /dev/vg01 /dev/dsk/c3t2d0
Volume group /dev/vg01 succerfully created
VGRA corrupted

Here it created VG but error is there
VGRA Corrupted

Re: vgcreate error

Jeeshan — Fri, 20 Mar 2009 12:46:53 GMT

did you check the latest patch?

Re: vgcreate error

amir syafiq — Fri, 20 Mar 2009 13:13:34 GMT

that the issues, before this i try to create vg but unsuccesful. Then download new LVM cumulative patch and install to the system with no error, after taht try to create the VG. succesfull but come with error VGRA corrupted.

same error if I create new LV, after reboot or vgchange system unable to activate the VG and mount the LV.

New patch:- PHKL_35970 - s700_800 11.11 LVM Cumulative Patch

Hi Amir

U can give One try for below

vgexport vg01
delete group file
dd if=/dev/null of=/dev/dsk/c3t2d0
pvcreate -f /dev/rdsk/c3t2d0
mkdir /dev/vg01
mknod /dev/group/vg01 c 64 0x20000
vgcreate -s 32 /dev/vg01 /dev/dsk/c3t2d0

Torsten. — Fri, 20 Mar 2009 13:24:42 GMT

Do you have any external devices connected to this servers built-in SCSI port?

Please post a full "ioscan -fn".

Re: vgcreate error

Duncan Edmonstone — Fri, 20 Mar 2009 13:26:47 GMT

I always worry when people indicate they installed just a single patch... Did you installl all the patch dependencies that go with the patch you mentioned?

amir syafiq — Fri, 20 Mar 2009 13:28:25 GMT

Thanks all for the guide.
I Already do that step 3 times, at last same thing happen VGRA corrupted. Is they a way to fix VGRA?

Re: vgcreate error

Torsten. — Fri, 20 Mar 2009 13:32:06 GMT

Please keep this in mind:

On this server the built-in SCSI port and the upper internal disk slot is the same bus.

It is recommended to have devices only on 1 side - internal or external.

Otherwise you will have very unpredictable behavior, I have seen very similar symptoms on a server with an "open" scsi cable connected to the external port - no devices, no termination - just an open bus.

Please check this.

Re: vgcreate error

amir syafiq — Fri, 20 Mar 2009 13:34:23 GMT

Hi Torsten
I will find the scsi device and connect to built-in scsi port, after that i'll post the ioscan -fn output.

Hi Duncan
Yes, I download with all dependency and install with default option. Patch installed with no error.
