vgcreate error

[amir syafiq]

Im using RP3410 with HPUX 11.11.

Command that I used to create VG:-

#ioscan –fnC disk

/dev/dsk/c2t1d0

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

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).
Using only 65535 PEs from this physical volume.
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.

I try dd and diskinfo command and look ok to me:-

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.

[amir syafiq]

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.

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.

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.

[amir syafiq]

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