lvsplit

Angelo Collazo — Tue, 22 Jul 2003 14:16:51 GMT

When executing the following:
#
# SPLIT mirror's for vg01
#
for i in $(ls /dev/vg01/*)
do
lvsplit $i >> /dbms/tmp/backupmirror.msg
done

I get this error:
"lvsplit: Logical volume "/dev/vg01/rdbms" is not a block special file."
Question:
1-) Why?
2-) What's the solution

TIA,
Angelo

Angelo,

It looks like it's a raw device file. Post an "ll /dev/vg01" so we can see what the corresponding cooked file might be.

lvsplit is done on logical volumes that are mirrored and part of volume groups.

lvsplit /dev/vg01/lvol1

The split off mirror needs to be part of vg01 or the original volume group and won't write to a /tmp file.

Hi Angelo:

You want to skip the raw devices so :

for i in $(ls in /dev/vg01/[!r]*)

...

Does ioscan show raw and "cooked" device files?

ioscan -fun -C disk

disk 0 10/0/14/0.0.0 sdisk CLAIMED DEVICE TEAC CD-532E-B
/dev/dsk/c0t0d0 /dev/rdsk/c0t0d0

If not reboot or use /sbin/insf
to install special (device) files

Hi,
you need to use block device with the lvsplit command.
Try

for i in $(vgdisplay -v /dev/vg01 |grep /dev/vg00/|awk '{print $3}')

Here is the option I will use on my noon backup scrip. This was suggested by James Ferguson(You want to skip the raw devices so : ). This should take care of my issue.

Solution: for i in $(ls in /dev/vg01/[!r]*)

Hi Angelo:

Sorry, there is a typographical error in my last post. This correct that error *and* skips the volume group's 'group' file and all *raw* devices:

#!/usr/bin/sh
for i in $(ls /dev/vg02/[!r]*)
do
[ $(basename ${i}) = group ] && continue
echo $i
done
exit 0

Regards!

Hi (again) Angelo

Yes, but per my second post:

...
for i in $(ls in /dev/vg01/[!r]*)

...should be:

for i in $(ls /dev/vg01/[!r]*)

...that is, drop the word "in"!!!

Regards!

for i in $(ls /dev/vg01/[!r]*)
do
[ $(basename ${i}) = group ] && continue

lvsplit $i >> /dbms/tmp/backupmirror.msg
done
