Problem with creating new file systems

[Vipin Singhal]

hi,
I have created new PV,VG,LV...
when I was creating file systems...
this is the error after creating two file systems:

# newfs -F vxfs -o largefiles /dev/vg75/rASPL_db_ORASPLD_data_dat01

Please suggest what to do?
Thanks

Please post a vgdisplay -v /dev/vg75

Looks like you may have a bad disk...

Do lvdisplay -v /dev/vg75/rASPL_db_ORASPLD_data_rbs01 |more
to see which disks are in that lvol...and the others...then do a dd:

dd if=/dev/dsk/cXtXdX of=/dev/null

where cXtXdX is the device of the disk...

If that is okay - then the disk should be fine - if it fails - then the disk should be replaced...

Rgds...Geoff

I tried with this one but still same problem:

# newfs -o largefiles /dev/vg75/rASPL_db_ORASPLD_data_rbs01
newfs: /etc/default/fs is used for determining the file system type

Okay - test those disks:

diskinfo /dev/rdsk/c23t4d1

diskinfo /dev/rdsk/c26t4d3

diskinfo /dev/rdsk/c29t4d3

Then dd:

dd if=/dev/dsk/c23t4d1 of=/dev/null

dd if=/dev/dsk/c26t4d3 of=/dev/null

dd if=/dev/dsk/c29t4d3 of=/dev/null

when i am giving this command:
# dd if=/dev/dsk/c29t4d3 of=/dev/null
it is taking too much time...still in process..

[Pete Randall]

When you do your dd command, add a block size to it or it will take forever. It can still take quite a long time but without a blocksize it probably won't finish until tomorrow sometime.

# dd if=/dev/dsk/c29t4d3 of=/dev/null bs=1024k

Should i run these commands again now:

vgchange -a n vg75
vgexport vg75
mkdir /dev/vg75
mknod /dev/vg75/group c 64 0x2f0000
pvcreate -f /dev/rdsk/c23t4d1
pvcreate -f /dev/rdsk/c26t4d3
pvcreate -f /dev/rdsk/c29t4d3
vgcreate /dev/vg75 /dev/dsk/c23t4d1
vgextend /dev/vg75 /dev/dsk/c26t4d3 /dev/dsk/c29t4d3

then lvcreate and newfs......
